Extrusions

Extrusions are one of the most common operations in CAD. They are used to create 3D objects from 2D Sketches by pulling them in an orthogonal direction. An extrusion needs a closed shape, an end and start (0 by default) measurement.

# 2 extrusions, first one is the outer shape, second one is a cut of the inner shape
        extrusion = Extrusion(square_shape_outer, self.height)

Extrusion can also be given a parameter cut to remove material in the same way.
