Selector String Modifiers


Axis Strings are: X, Y, Z, XY, YZ, XZ
Mod Description
| Parallel to = ParallelDirSelector
# Perpendicular to = PerpendicularDirSelector
+/- Pos/Neg direction = DirectionSelector
> Max = DirectionMinMaxSelector(directionMax=True)
< Min = DirectionMinMaxSelector(directionMax=False)
% Curve/surface type = TypeSelector
Eg: select the top face (> in Z direction) = .faces(">Z")

Selector Methods


CadQuery selector strings and classes allow filtering to select objects.
Selector Methods Selector Classes
faces(selector) NearestToPointSelector(pnt)
edges(selector) ParallelDirSelector(vector)
vertices(selector) PerpendicularDirSelector(vector)
solids(selector) DirectionMinMaxSelector(vector)
shells(selector) RadiusNthSelector(n)
AndSelector(selector, selector)
SumSelector(selector, selector)
SubtractSelector(selector, selector)
InverseSelector(selector)

Workplane Positioning

translate
(Vector(x, y, z))		 rotateAboutCenter
(Vector(x, y, z), angleDegrees)		 rotate
(Vector(x, y, z), Vector(x, y, z), angleDegrees)
Position a workplane relative to an existing feature with:
.workplane(offset, origin)
sets the offset perpendicular to the current plane
sets the origin relative to (0,0) on the current plane

Named Planes


Direction references refer to the global directions.
Name xDir yDir zDir
XY +x +y +z
YZ +y +z +x
XZ +x +z -y
front +x +y +z
back -x +y -z
left +z +y -x
right -z +y +x
top +x -z +y
bottom +x +z -y

Examples of Filtering Faces


All types of filters work on faces. In most cases, the selector refers to the direction of the normal vector of the face. If a face is not planar, selectors are evaluated at the center of mass of the face. This can lead to results that are quite unexpected.
Selector Selector Class Selects # Objects Returned
+Z DirectionSelector Faces with normal in +z direction 0..many
|Z ParallelDirSelector Faces parallel to xy plane 0..many
-X DirectionSelector Faces with normal in neg x direction 0..many
#Z PerpendicularDirSelector Faces perpendicular to z direction 0..many
%Plane TypeSelector Faces of type plane 0..many
>Y DirectionMinMaxSelector Face farthest in the positive y dir 0 or 1
<Y DirectionMinMaxSelector Face farthest in the negative y dir 0 or 1

Examples of Filtering Edges


Some filter types are not supported for edges. The selector usually refers to the direction of the edge. Non-linear edges are not selected for any selectors except type (%). Non-linear edges are never returned when these filters are applied.
Selector Selector Class Selects # Objects Returned
+Z DirectionSelector Edges aligned in the Z direction 0..many
|Z ParallelDirSelector Edges parallel to z direction 0..many
-X DirectionSelector Edges aligned in neg x direction 0..many
#Z PerpendicularDirSelector Edges perpendicular to z direction 0..many
%Plane TypeSelector Edges type line 0..many
>Y DirectionMinMaxSelector Edges farthest in the positive y dir 0 or 1
<Y DirectionMinMaxSelector Edges farthest in the negative y dir 0 or 1

Examples of Filtering Vertices


Only a few of the filter types apply to vertices. The location of the vertex is the subject of the filter.
Selector Selector Class Selects
>Y DirectionMinMaxSelector Vertices farthest in the +Y dir
<Y DirectionMinMaxSelector Vertices farthest in the -Y dir
>>Y[-2] CenterNthSelector 2nd farthest vertex in the +Y dir
<<Y[0] CenterNthSelector 1st closest vertex in the Y dir
