Plane

rotated
(rotate=0, 0, 0)[source]¶ Returns a copy of this plane, rotated about the specified axes
Since the z axis is always normal the plane, rotating around Z will always produce a plane that is parallel to this one.
The origin of the workplane is unaffected by the rotation.
Rotations are done in order x, y, z. If you need a different order, manually chain together multiple rotate() commands.
 Parameters
rotate – Vector [xDegrees, yDegrees, zDegrees]
 Returns
a copy of this plane rotated as requested.

setOrigin2d
(x, y)[source]¶ Set a new origin in the plane itself
Set a new origin in the plane itself. The plane’s orientation and xDrection are unaffected.
 Parameters
x (float) – offset in the x direction
y (float) – offset in the y direction
 Returns
void
The new coordinates are specified in terms of the current 2d system. As an example:
p = Plane.XY() p.setOrigin2d(2, 2) p.setOrigin2d(2, 2)
results in a plane with its origin at (x, y) = (4, 4) in global coordinates. Both operations were relative to local coordinates of the plane.

toLocalCoords
(obj)[source]¶ Project the provided coordinates onto this plane
 Parameters
obj – an object or vector to convert
 Returns
an object of the same type, but converted to local coordinates
Most of the time, the zcoordinate returned will be zero, because most operations based on a plane are all 2d. Occasionally, though, 3d points outside of the current plane are transformed. One such example is
Workplane.box()
, where 3d corners of a box are transformed to orient the box in space correctly.

all wires must be closed
there cannot be any intersecting or selfintersecting wires
wires must be listed from outside in
more than one levels of nesting is not supported reliably

StringSyntaxSelector
(selectorString)[source]¶ Bases:

and its subclassesFiltering works differently depending on the type of object list being filtered.
 Parameters
selectorString – A twopart selector string, [selector][axis]
 Returns
objects that match the specified selector
*Modfiers* are

Logical AND, e.g. >X and >Y
 or
Logical OR, e.g. X or Y
 not
Logical NOT, e.g. not #XY
 exc(ept)
Set difference (equivalent to AND NOT): X exc >Z
Finally, it is also possible to use even more complex expressions with nesting and arbitrary number of terms, e.g.
(not >X[0] and #XY) or >XY[0]

add
(obj: Iterable[Union[cadquery.occ_impl.geom.Vector, cadquery.occ_impl.geom.Location, cadquery.occ_impl.shapes.Shape]]) → T Adds an object or a list of objects to the stack
 Parameters
obj (a Workplane, CAD primitive, or list of CAD primitives) – an object to add
 Returns
a Workplane with the requested operation performed
If an Workplane object, the values of that object’s stack are added. If a list of cad primitives, they are all added. If a single CAD primitive then it is added.
Used in rare cases when you need to combine the results of several CQ results into a single Workplane object. Shelling is one common example.

all
()[source]¶ Return a list of all CQ objects on the stack.
useful when you need to operate on the elements individually.
Contrast with vals, which returns the underlying objects for all of the items on the stack
 Parameters
self (~T) –
 Return type
List
[~T]

box
(length, width, height, centered=True, combine=True, clean=True)[source]¶ Return a 3d box with specified dimensions for each object on the stack.
 Parameters
length (float > 0) – box size in X direction
width (float > 0) – box size in Y direction
height (float > 0) – box size in Z direction
centered (
Union
[bool
,Tuple
[bool
,bool
,bool
]]) – If True, the box will be centered around the reference point. If False, the corner of the box will be on the reference point and it will extend in the positive x, y and z directions. Can also use a 3tuple to specify centering along each axis.combine (
bool
) – should the results be combined with other solids on the stack (and each other)?clean (
bool
) – callclean()
afterwards to have a clean shape
One box is created for each item on the current stack. If no items are on the stack, one box using the current workplane center is created.
If combine is true, the result will be a single object on the stack. If a solid was found in the chain, the result is that solid with all boxes produced fused onto it otherwise, the result is the combination of all the produced boxes.
If combine is false, the result will be a list of the boxes produced.
Most often boxes form the basis for a part:
# make a single box with lower left corner at origin s = Workplane().box(1, 2, 3, centered=False)
But sometimes it is useful to create an array of them:
# create 4 small square bumps on a larger base plate: s = ( Workplane(). box(4, 4, 0.5). faces(">Z"). workplane(). rect(3, 3, forConstruction=True) .vertices() .box(0.25, 0.25, 0.25, combine=True) )
 Parameters

cboreHole
(diameter, cboreDiameter, cboreDepth, depth=None, clean=True)[source]¶ Makes a counterbored hole for each item on the stack.
 Parameters
diameter (float > 0) – the diameter of the hole
cboreDiameter (float > 0 and > diameter) – the diameter of the cbore
cboreDepth (float > 0) – depth of the counterbore
depth (float > 0 or None to drill thru the entire part.) – the depth of the hole
clean (boolean) – call
clean()
afterwards to have a clean shape
The surface of the hole is at the current workplane plane.
One hole is created for each item on the stack. A very common use case is to use a construction rectangle to define the centers of a set of holes, like so:
s = Workplane(Plane.XY()).box(2,4,0.5).faces(">Z").workplane() .rect(1.5,3.5,forConstruction=True) .vertices().cboreHole(0.125, 0.25,0.125,depth=None)
This sample creates a plate with a set of holes at the corners.
Plugin Note: this is one example of the power of plugins. Counterbored holes are quite time consuming to create, but are quite easily defined by users.

center
(x, y)[source]¶ Shift local coordinates to the specified location.
The location is specified in terms of local coordinates.
 Parameters
x (float) – the new x location
y (float) – the new y location
 Return type
~T
 Returns
the workplane object, with the center adjusted.
The current point is set to the new center. This method is useful to adjust the center point after it has been created automatically on a face, but not where you’d like it to be.
In this example, we adjust the workplane center to be at the corner of a cube, instead of the center of a face, which is the default:
#this workplane is centered at x=0.5,y=0.5, the center of the upper face s = Workplane().box(1,1,1).faces(">Z").workplane() s = s.center(0.5,0.5) # move the center to the corner t = s.circle(0.25).extrude(0.2) assert ( t.faces().size() == 9 ) # a cube with a cylindrical nub at the top right corner
The result is a cube with a round boss on the corner
 Parameters
self (~T) –
x (
float
) –y (
float
) –

chamfer
(length, length2=None)[source]¶ Chamfers a solid on the selected edges.
The edges on the stack are chamfered. The solid to which the edges belong must be in the parent chain of the selected edges.
Optional parameter length2 can be supplied with a different value than length for a chamfer that is shorter on one side longer on the other side.
 Parameters
length (positive float) – the length of the chamfer, must be greater than zero
length2 (positive float) – optional parameter for asymmetrical chamfer
 Raises
ValueError – if at least one edge is not selected
ValueError – if the solid containing the edge is not in the chain
 Return type
~T
 Returns
cq object with the resulting solid selected.
This example will create a unit cube, with the top edges chamfered:
s = Workplane("XY").box(1,1,1).faces("+Z").chamfer(0.1)
This example will create chamfers longer on the sides:
s = Workplane("XY").box(1,1,1).faces("+Z").chamfer(0.2, 0.1)
 Parameters
self (~T) –

circle
(radius, forConstruction=False)[source]¶ Make a circle for each item on the stack.
 Parameters
radius (float > 0) – radius of the circle
forConstruction (true if the wires are for reference, false if they are creating part geometry) – should the new wires be reference geometry only?
 Return type
~T
 Returns
a new CQ object with the created wires on the stack
A common use case is to use a forconstruction rectangle to define the centers of a hole pattern:
s = Workplane().rect(4.0,4.0,forConstruction=True).vertices().circle(0.25)
Creates 4 circles at the corners of a square centered on the origin. Another common case is to use successive circle() calls to create concentric circles. This works because the center of a circle is its reference point:
s = Workplane().circle(2.0).circle(1.0)
Creates two concentric circles, which when extruded will form a ring.
 Future Enhancements:
better way to handle forConstruction project points not in the workplane plane onto the workplane plane
 Parameters
self (~T) –

clean
()[source]¶ Cleans the current solid by removing unwanted edges from the faces.
Normally you don’t have to call this function. It is automatically called after each related operation. You can disable this behavior with clean=False parameter if method has any. In some cases this can improve performance drastically but is generally disadvised since it may break some operations such as fillet.
Note that in some cases where lots of solid operations are chained, clean() may actually improve performance since the shape is ‘simplified’ at each step and thus next operation is easier.
Also note that, due to limitation of the underlying engine, clean may fail to produce a clean output in some cases such as spherical faces.
 Parameters
self (~T) –
 Return type
~T

close
()[source]¶ End 2d construction, and attempt to build a closed wire.
 Return type
~T
 Returns
a CQ object with a completed wire on the stack, if possible.
After 2d drafting with methods such as lineTo, threePointArc, tangentArcPoint and polyline, it is necessary to convert the edges produced by these into one or more wires.
When a set of edges is closed, cadQuery assumes it is safe to build the group of edges into a wire. This example builds a simple triangular prism:
s = Workplane().lineTo(1,0).lineTo(1,1).close().extrude(0.2)
 Parameters
self (~T) –

combine
(clean=True, glue=False, tol=None)[source]¶ Attempts to combine all of the items on the stack into a single item. WARNING: all of the items must be of the same type!
 Parameters

After the operation, the returned solid is also the context solid.
 Parameters
otherCQToCombine (
Optional
[Workplane
]) – another CadQuery to combine. Return type
Workplane
 Returns
a cQ object with the resulting combined solid on the stack.
Most of the time, both objects will contain a single solid, which is combined and returned on the stack of the new object.

compounds
(selector=None, tag=None)[source]¶ Select compounds on the stack, optionally filtering the selection. If there are multiple objects on the stack, they are collected and a list of all the distinct compounds is returned.
 Parameters
selector (None, a Selector object, or a string selector expression.) – A selector
tag (string) – if set, search the tagged CQ object instead of self
 Return type
~T
 Returns
a CQ object who’s stack contains all of the distinct solids of all objects on the current stack, filtered by the provided selector.
A compound contains multiple CAD primitives that resulted from a single operation, such as a union, cut, split, or fillet. Compounds can contain multiple edges, wires, or solids.

cskHole
(diameter, cskDiameter, cskAngle, depth=None, clean=True)[source]¶ Makes a countersunk hole for each item on the stack.
 Parameters

depth (float > 0 or None to drill thru the entire part.) – the depth of the hole
clean (boolean) – call
clean()
afterwards to have a clean shape
The surface of the hole is at the current workplane.
One hole is created for each item on the stack. A very common use case is to use a construction rectangle to define the centers of a set of holes, like so:
s = Workplane(Plane.XY()).box(2,4,0.5).faces(">Z").workplane() .rect(1.5,3.5,forConstruction=True) .vertices().cskHole(0.125, 0.25,82,depth=None)
This sample creates a plate with a set of holes at the corners.

each
(callback, useLocalCoordinates=False)[source]¶ Runs the provided function on each value in the stack, and collects the return values into a new CQ object.
Special note: a newly created workplane always has its center point as its only stack item
 Parameters
callBackFunction – the function to call for each item on the current stack.
useLocalCoordinates (boolean) – should values be converted from local coordinates first?
The callback function must accept one argument, which is the item on the stack, and return one object, which is collected. If the function returns None, nothing is added to the stack. The object passed into the callBackFunction is potentially transformed to local coordinates, if useLocalCoordinates is true
useLocalCoordinates is very useful for plugin developers.
If false, the callback function is assumed to be working in global coordinates. Objects created are added asis, and objects passed into the function are sent in using global coordinates
If true, the calling function is assumed to be working in local coordinates. Objects are transformed to local coordinates before they are passed into the callback method, and result objects are transformed to global coordinates after they are returned.
This allows plugin developers to create objects in local coordinates, without worrying about the fact that the working plane is different than the global coordinate system.
TODO: wrapper object for Wire will clean up forConstruction flag everywhere
 Parameters

callback (
Callable
[[Union
[Vector
,Location
,Shape

]) –
 Return type
~T

eachpoint
(callback, useLocalCoordinates=False)[source]¶ Same as each(), except each item on the stack is converted into a point before it is passed into the callback function.
 Return type
~T
 Returns
CadQuery object which contains a list of vectors (points ) on its stack.
 Parameters
useLocalCoordinates (boolean) – should points be in local or global coordinates
The resulting object has a point on the stack for each object on the original stack. Vertices and points remain a point. Faces, Wires, Solids, Edges, and Shells are converted to a point by using their center of mass.
If the stack has zero length, a single point is returned, which is the center of the current workplane/coordinate system
 Parameters
self (~T) –
callback (
Callable
[[Location

]) –

edges
(selector=None, tag=None)[source]¶ Select the edges of objects on the stack, optionally filtering the selection. If there are multiple objects on the stack, the edges of all objects are collected and a list of all the distinct edges is returned.
 Parameters
selector (None, a Selector object, or a string selector expression.) – A selector
tag (string) – if set, search the tagged CQ object instead of self
 Return type
~T
 Returns
a CQ object who’s stack contains all of the distinct edges of all objects on the current stack, filtered by the provided selector.
If there are no edges for any objects on the current stack, an empty CQ object is returned
The typical use is to select the edges of a single object on the stack. For example:
CQ(aCube).faces("+Z").edges().size()
returns 4, because a cube has one face with a normal in the +Z direction. Similarly:
CQ(aCube).edges().size()
returns 12, because a cube has a total of 12 edges, And:
CQ(aCube).edges("Z").size()
returns 4, because a cube has 4 edges parallel to the z direction
 Parameters
self (~T) –

ellipse
(x_radius, y_radius, rotation_angle=0.0, forConstruction=False)[source]¶ Make an ellipse for each item on the stack.
 Parameters

forConstruction (true if the wires are for reference, false if they are creating part geometry) – should the new wires be reference geometry only?
 Return type
~T
 Returns
a new CQ object with the created wires on the stack
NOTE Due to a bug in opencascade (https://tracker.dev.opencascade.org/view.php?id=31290) the center of mass (equals center for next shape) is shifted. To create concentric ellipses use Workplane(“XY”)
.center(10, 20).ellipse(100,10) .center(0, 0).ellipse(50, 5)
 Parameters

extrude
(distance, combine=True, clean=True, both=False, taper=None)[source]¶ Use all unextruded wires in the parent chain to create a prismatic solid.
 Parameters

clean()
afterwards to have a clean shapeboth (boolean) – extrude in both directions symmetrically
taper (float) – angle for optional tapered extrusion
 Return type
~T
 Returns
a CQ object with the resulting solid selected.
extrude always adds material to a part.
The returned object is always a CQ object, and depends on whether combine is True, and whether a context solid is already defined:
if combine is False, the new value is pushed onto the stack.
if combine is true, the value is combined with the context solid if it exists, and the resulting solid becomes the new context solid.
 FutureEnhancement:
Support for nonprismatic extrusion ( IE, sweeping along a profile, not just perpendicular to the plane extrude to surface. this is quite tricky since the surface selected may not be planar

 Parameters
selector (None, a Selector object, or a string selector expression.) – A selector
tag (string) – if set, search the tagged CQ object instead of self
 Return type
~T
 Returns
a CQ object who’s stack contains all of the distinct faces of all objects on the current stack, filtered by the provided selector.
If there are no vertices for any objects on the current stack, an empty CQ object is returned.
The typical use is to select the faces of a single object on the stack. For example:
CQ(aCube).faces("+Z").size()
returns 1, because a cube has one face with a normal in the +Z direction. Similarly:
CQ(aCube).faces().size()
returns 6, because a cube has a total of 6 faces, And:
CQ(aCube).faces("Z").size()
returns 2, because a cube has 2 faces having normals parallel to the z direction
 Parameters
self (~T) –

fillet
(radius)[source]¶ Fillets a solid on the selected edges.
The edges on the stack are filleted. The solid to which the edges belong must be in the parent chain of the selected edges.
 Parameters
radius (positive float) – the radius of the fillet, must be > zero
 Raises
ValueError – if at least one edge is not selected
ValueError – if the solid containing the edge is not in the chain
 Return type
~T
 Returns
cq object with the resulting solid selected.
This example will create a unit cube, with the top edges filleted:
s = Workplane().box(1,1,1).faces("+Z").edges().fillet(0.1)
 Parameters
self (~T) –

findFace
(searchStack=True, searchParents=True)[source]¶ Finds the first face object in the chain, searching from the current node backwards through parents until one is found.
 Parameters
searchStack (
bool
) – should objects on the stack be searched first.searchParents (

) – should parents be searched?
 Return type
Face
 Returns
A face or None if no face is found.

findSolid
(searchStack=True, searchParents=True)[source]¶ Finds the first solid object in the chain, searching from the current node backwards through parents until one is found.
 Parameters
searchStack (
bool
) – should objects on the stack be searched first?searchParents (
bool

ValueError – if no solid is found
This function is very important for chains that are modifying a single parent object, most often a solid.
Most of the time, a chain defines or selects a solid, and then modifies it using workplanes or other operations.
Plugin Developers should make use of this method to find the solid that should be modified, if the plugin implements a unary operation, or if the operation will automatically merge its results with an object already on the stack.

hole
(diameter, depth=None, clean=True)[source]¶ Makes a hole for each item on the stack.
 Parameters
diameter (float > 0) – the diameter of the hole
depth (float > 0 or None to drill thru the entire part.) – the depth of the hole
clean (boolean) – call
clean()
afterwards to have a clean shape
The surface of the hole is at the current workplane.
One hole is created for each item on the stack. A very common use case is to use a construction rectangle to define the centers of a set of holes, like so:
s = Workplane(Plane.XY()).box(2,4,0.5).faces(">Z").workplane() .rect(1.5,3.5,forConstruction=True) .vertices().hole(0.125, 0.25,82,depth=None)
This sample creates a plate with a set of holes at the corners.
Plugin Note: this is one example of the power of plugins. CounterSunk holes are quite time consuming to create, but are quite easily defined by users.

WARNING: This version returns the same cq object instead of a new one– the old object is not accessible.
 Future Enhancements:
A version of this method that returns a transformed copy, rather than modifying the originals
This method doesnt expose a very good interface, because the axis of rotation could be inconsistent between multiple objects. This is because the beginning of the axis is variable, while the end is fixed. This is fine when operating on one object, but is not cool for multiple.
 Parameters
self (~T) –

sagittaArc
(endPoint, sag, forConstruction=False)[source]¶ Draw an arc from the current point to endPoint with an arc defined by the sag (sagitta).

bool

section
(height=0.0)[source]¶ Slices current solid at the given height.

 Return type
~T
 Returns
a CQ object with the resulting face(s).

shell
(thickness, kind='arc')[source]¶ Remove the selected faces to create a shell of the specified thickness.
To shell, first create a solid, and in the same chain select the faces you wish to remove.
 Parameters
thickness (
float
) – a positive float, representing the thickness of the desired shell. Negative values shell inwards, positive values shell outwards.kind (
Literal
[‘arc’, ‘intersection’]) – kind of joints, intersetion or arc (default: arc).
 Raises
ValueError – if the current stack contains objects that are not faces of a solid further up in the chain.
 Return type
~T
 Returns
a CQ object with the resulting shelled solid selected.
This example will create a hollowed out unit cube, where the top most face is open, and all other walls are 0.2 units thick:
Workplane().box(1,1,1).faces("+Z").shell(0.2)
Shelling is one of the cases where you may need to use the add method to select several faces. For example, this example creates a 3walled corner, by removing three faces of a cube:
s = Workplane().box(1,1,1) s1 = s.faces("+Z") s1.add(s.faces("+Y")).add(s.faces("+X")) self.saveModel(s1.shell(0.2))
This fairly yucky syntax for selecting multiple faces is planned for improvement
Note: When sharp edges are shelled inwards, they remain sharp corners, but outward shells are automatically filleted, because an outward offset from a corner generates a radius.
 Future Enhancements:
Better selectors to make it easier to select multiple faces
 Parameters
self (~T) –

shells
(selector=None, tag=None)[source]¶ Select the shells of objects on the stack, optionally filtering the selection. If there are multiple objects on the stack, the shells of all objects are collected and a list of all the distinct shells is returned.

tag (string) – if set, search the tagged CQ object instead of self
 Return type
~T
 Returns
a CQ object who’s stack contains all of the distinct solids of all objects on the current stack, filtered by the provided selector.
If there are no shells for any objects on the current stack, an empty CQ object is returned
Most solids will have a single shell, which represents the outer surface. A shell will typically be composed of multiple faces.
 Parameters
self (~T) –

slot2D
(length, diameter, angle=0)[source]¶ Creates a rounded slot for each point on the stack.
 Parameters
diameter (
float
) – desired diameter, or width, of slotlength (
float
) – desired end to end length of slotangle (
float
) – angle of slot in degrees, with 0 being along xaxis
 Return type
~T
 Returns
a new CQ object with the created wires on the stack
Can be used to create arrays of slots, such as in cooling applications:
result = cq.Workplane(“XY”).box(10,25,1).rarray(1,2,1,10).slot2D(8,1,0).cutThruAll()
 Parameters
self (~T) –

solids
(selector=None, tag=None)[source]¶ Select the solids of objects on the stack, optionally filtering the selection. If there are multiple objects on the stack, the solids of all objects are collected and a list of all the distinct solids is returned.
 Parameters

tag (string) – if set, search the tagged CQ object instead of self
 Return type
~T
 Returns
a CQ object who’s stack contains all of the distinct solids of all objects on the current stack, filtered by the provided selector.
If there are no solids for any objects on the current stack, an empty CQ object is returned
The typical use is to select the a single object on the stack. For example:
CQ(aCube).solids().size()
returns 1, because a cube consists of one solid.
It is possible for single CQ object ( or even a single CAD primitive ) to contain multiple solids.
 Parameters

,Tuple
[bool
,bool
,bool
]]) – If True, the sphere will be centered around the reference point. If False, the corner of a bounding box around the sphere will be on the reference point and it will extend in the positive x, y and z directions. Can also use a 3tuple to specify centering along each axis.combine (true to combine shapes, false otherwise) – Whether the results should be combined with other solids on the stack (and each other)
clean (
bool
) – callclean()
afterwards to have a clean shape
 Return type
~T
 Returns
A sphere object for each point on the stack
One sphere is created for each item on the current stack. If no items are on the stack, one box using the current workplane center is created.
If combine is true, the result will be a single object on the stack. If a solid was found in the chain, the result is that solid with all spheres produced fused onto it otherwise, the result is the combination of all the produced spheres.
If combine is false, the result will be a list of the spheres produced.

 Return type
~T
 Returns
a CQ object who’s stack contains the distinct vertices of all objects on the current stack, after being filtered by the selector, if provided
If there are no vertices for any objects on the current stack, an empty CQ object is returned
The typical use is to select the vertices of a single object on the stack. For example:
Workplane().box(1,1,1).faces("+Z").vertices().size()
returns 4, because the topmost face of cube will contain four vertices. While this:
Workplane().box(1,1,1).faces().vertices().size()
returns 8, because a cube has a total of 8 vertices
Note Circles are peculiar, they have a single vertex at the center!

[float
,float
,float

]) – The direction vector (or tuple) for the major axis of the wedgecentered (
Union
[bool
,Tuple
[bool
,bool
,bool

bool
) – Whether the results should be combined with other solids on the stack (and each other)clean (
bool
) – True to attempt to have the kernel clean up the geometry, False otherwise
 Return type
~T
 Returns
A wedge object for each point on the stack
One wedge is created for each item on the current stack. If no items are on the stack, one wedge using the current workplane center is created.
If combine is True, the result will be a single object on the stack. If a solid was found in the chain, the result is that solid with all wedges produced fused onto it otherwise, the result is the combination of all the produced wedges.
If combine is False, the result will be a list of the wedges produced.
 Parameters
self (~T) –

wire
(forConstruction=False)[source]¶ Returns a CQ object with all pending edges connected into a wire.
All edges on the stack that can be combined will be combined into a single wire object, and other objects will remain on the stack unmodified. If there are no pending edges, this method will just return self.
 Parameters
forConstruction (
bool
) – whether the wire should be used to make a solid, or if it is just for reference
This method is primarily of use to plugin developers making utilities for 2d construction. This method should be called when a user operation implies that 2d construction is finished, and we are ready to begin working in 3d.
SEE ‘2d construction concepts’ for a more detailed explanation of how CadQuery handles edges, wires, etc.
Any non edges will still remain.
 Parameters
self (~T) –
 Return type
~T

wires
(selector=None, tag=None)[source]¶ Select the wires of objects on the stack, optionally filtering the selection. If there are multiple objects on the stack, the wires of all objects are collected and a list of all the distinct wires is returned.
 Parameters
selector (None, a Selector object, or a string selector expression.) – A selector
tag (string) – if set, search the tagged CQ object instead of self
 Return type
~T
 Returns
a CQ object who’s stack contains all of the distinct wires of all objects on the current stack, filtered by the provided selector.
If there are no wires for any objects on the current stack, an empty CQ object is returned
The typical use is to select the wires of a single object on the stack. For example:
CQ(aCube).faces("+Z").wires().size()
returns 1, because a face typically only has one outer wire
 Parameters
self (~T) –

workplane
(offset=0.0, invert=False, centerOption='ProjectedOrigin', origin=None)[source]¶ Creates a new 2D workplane, located relative to the first face on the stack.
 Parameters
offset (float or None=0.0) – offset for the work plane in the Z direction. Default
invert (boolean or None=False) – invert the Z direction from that of the face.
centerOption (string or None='ProjectedOrigin') – how local origin of workplane is determined.
origin (Vector or None) – origin for plane center, requires ‘ProjectedOrigin’ centerOption.
 Return type
Workplane object ( which is a subclass of CQ )
The first element on the stack must be a face, a set of coplanar faces or a vertex. If a vertex, then the parent item on the chain immediately before the vertex must be a face.
The result will be a 2d working plane with a new coordinate system set up as follows:
The centerOption parameter sets how the center is defined. Options are ‘CenterOfMass’, ‘CenterOfBoundBox’, or ‘ProjectedOrigin’. ‘CenterOfMass’ and ‘CenterOfBoundBox’ are in relation to the selected face(s) or vertex (vertices). ‘ProjectedOrigin’ uses by default the current origin or the optional origin parameter (if specified) and projects it onto the plane defined by the selected face(s).
The Z direction will be normal to the plane of the face,computed at the center point.
The X direction will be parallel to the xy plane. If the workplane is parallel to the global xy plane, the x direction of the workplane will coincide with the global x direction.
Most commonly, the selected face will be planar, and the workplane lies in the same plane of the face ( IE, offset=0). Occasionally, it is useful to define a face offset from an existing surface, and even more rarely to define a workplane based on a face that is not planar.
To create a workplane without first having a face, use the Workplane() method.
 Future Enhancements:
Allow creating workplane from planar wires
Allow creating workplane based on an arbitrary point on a face, not just the center. For now you can work around by creating a workplane and then offsetting the center afterwards.
 Parameters
self (~T) –

Returns, list of lists.

DirectionSelector
(vector, tolerance=0.0001)[source]¶ Bases:
cadquery.selectors.BaseDirSelector
Selects objects aligned with the provided direction.
 Applicability:
Linear Edges Planar Faces
Use the string syntax shortcut +/(XYZ) if you want to select based on a cardinal direction.
Example:
CQ(aCube).faces(DirectionSelector((0, 0, 1))
selects faces with a normals in the z direction, and is equivalent to:
CQ(aCube).faces("+Z")
 Parameters
vector (
Vector
) –tolerance (
float
) –

class
cadquery.selectors.
InverseSelector
(selector)[source]¶ Bases:
cadquery.selectors.Selector
Inverts the selection of given selector. In other words, selects all objects that is not selected by given selector.

class
cadquery.selectors.
LengthNthSelector
(n, directionMax=True, tolerance=0.0001)[source]¶ Bases:
cadquery.selectors._NthSelector
Select the object(s) with the Nth length
 Applicability:
All Edge and Wire objects
 Parameters
n (
int
) –directionMax (
bool
) –tolerance (
float
) –

class
cadquery.selectors.
NearestToPointSelector
(pnt)[source]¶ Bases:
cadquery.selectors.Selector
Selects object nearest the provided point.
If the object is a vertex or point, the distance is used. For other kinds of shapes, the center of mass is used to to compute which is closest.
Applicability: All Types of Shapes
Example:
CQ(aCube).vertices(NearestToPointSelector((0,1,0))
returns the vertex of the unit cube closest to the point x=0,y=1,z=0

class
cadquery.selectors.
ParallelDirSelector
(vector, tolerance=0.0001)[source]¶ Bases:
cadquery.selectors.BaseDirSelector
Selects objects parallel with the provided direction.
 Applicability:
Linear Edges Planar Faces
Use the string syntax shortcut (XYZ) if you want to select based on a cardinal direction.
Example:
CQ(aCube).faces(ParallelDirSelector((0, 0, 1))
selects faces with a normals in the z direction, and is equivalent to:
CQ(aCube).faces("Z")
 Parameters
vector (
Vector
) –tolerance (
float
) –

class
cadquery.selectors.
PerpendicularDirSelector
(vector, tolerance=0.0001)[source]¶ Bases:
cadquery.selectors.BaseDirSelector
Selects objects perpendicular with the provided direction.
 Applicability:
Linear Edges Planar Faces
Use the string syntax shortcut #(XYZ) if you want to select based on a cardinal direction.
Example:
CQ(aCube).faces(PerpendicularDirSelector((0, 0, 1))
selects faces with a normals perpendicular to the z direction, and is equivalent to:
CQ(aCube).faces("#Z")
 Parameters
vector (
Vector
) –tolerance (
float
) –

class
cadquery.selectors.
RadiusNthSelector
(n, directionMax=True, tolerance=0.0001)[source]¶ Bases:
cadquery.selectors._NthSelector
Select the object with the Nth radius.
 Applicability:
All Edge and Wires.
Will ignore any shape that can not be represented as a circle or an arc of a circle.
 Parameters
n (
int
) –directionMax (
bool
) –tolerance (
float
) –

class
cadquery.selectors.
Selector
[source]¶ Bases:
object
Filters a list of objects.
Filters must provide a single method that filters objects.

class
cadquery.selectors.
StringSyntaxSelector
(selectorString)[source]¶ Bases:
cadquery.selectors.Selector
Filter lists objects using a simple string syntax. All of the filters available in the string syntax are also available ( usually with more functionality ) through the creation of fullfledged selector objects. see
Selector
and its subclassesFiltering works differently depending on the type of object list being filtered.
 Parameters
selectorString – A twopart selector string, [selector][axis]
 Returns
objects that match the specified selector
*Modfiers* are
('','+','','<','>','%')
 
parallel to ( same as
ParallelDirSelector
). Can return multiple objects. #
perpendicular to (same as
PerpendicularDirSelector
) +
positive direction (same as
DirectionSelector
) 
negative direction (same as
DirectionSelector
) >
maximize (same as
DirectionMinMaxSelector
with directionMax=True) <
minimize (same as
DirectionMinMaxSelector
with directionMax=False ) %
curve/surface type (same as
TypeSelector
)
*axisStrings* are:
X,Y,Z,XY,YZ,XZ
or(x,y,z)
which defines an arbitrary directionIt is possible to combine simple selectors together using logical operations. The following operations are suuported
 and
Logical AND, e.g. >X and >Y
 or
Logical OR, e.g. X or Y
 not
Logical NOT, e.g. not #XY
 exc(ept)
Set difference (equivalent to AND NOT): X exc >Z
Finally, it is also possible to use even more complex expressions with nesting and arbitrary number of terms, e.g.
(not >X[0] and #XY) or >XY[0]
Selectors are a complex topic: see String Selectors Reference for more information

class
cadquery.selectors.
SubtractSelector
(left, right)[source]¶ Bases:
cadquery.selectors.BinarySelector
Difference selector. Substract results of a selector from another selectors results.

class
cadquery.selectors.
SumSelector
(left, right)[source]¶ Bases:
cadquery.selectors.BinarySelector
Union selector. Returns the sum of two selectors results.

class
cadquery.selectors.
TypeSelector
(typeString)[source]¶ Bases:
cadquery.selectors.Selector
Selects objects having the prescribed geometry type.
 Applicability:
Faces: PLANE, CYLINDER, CONE, SPHERE, TORUS, BEZIER, BSPLINE, REVOLUTION, EXTRUSION, OFFSET, OTHER Edges: LINE, CIRCLE, ELLIPSE, HYPERBOLA, PARABOLA, BEZIER, BSPLINE, OFFSET, OTHER
You can use the string selector syntax. For example this:
CQ(aCube).faces ( TypeSelector("PLANE") )
will select 6 faces, and is equivalent to:
CQ(aCube).faces( "%PLANE" )
 Parameters
typeString (
str
) –
