The DraftAngle can be used to apply an angle to specific faces of a shape. Specify the angle and faces to perform the draft angle on. It will use the position and direction to define the neutral plane. If more control is needed, an operations list can be provided with a face, direction, angle, and neutral plane for each face.
Like Fillet and Chamfer, the disabled flag can be used to disable the operation for debugging.

enamldef Assembly(Part):

DraftAngle:
transparency = 0.5
angle = radians(15)
position = (0, 0, box.dz)
faces = [self.children[0].topology.faces[0]]
Fillet:
radius = 1
operations = [
e for i, e in enumerate(box.topology.edges)
if i in (4, 6)
]
Box: box:
dx = 10
dy = 12
dz = 10
Note: The algorithm will select adjacent faces automatically when fillets are present.
Another example demonstrating how to easily add an angled pitch to walls using draft angle which may be of use for making molds or castings.
