# Create a plate with two polygons cut through it
|
|
# 1. Establishes a workplane that an object can be built on.
|
|
# 1a. Uses the named plane orientation "front" to define the workplane, meaning
|
|
# that the positive Z direction is "up", and the negative Z direction
|
|
# is "down".
|
|
# 2. A 3D box is created in one box() operation to represent the plate.
|
|
# 2a. The box is centered around the origin, which creates a result that may
|
|
# be unituitive when the polygon cuts are made.
|
|
# 3. 2 points are pushed onto the stack and will be used as centers for the
|
|
# polygonal holes.
|
|
# 4. The two polygons are created, on for each point, with one call to
|
|
# polygon() using the number of sides and the circle that bounds the
|
|
# polygon.
|
|
# 5. The polygons are cut thru all objects that are in the line of extrusion.
|
|
# 5a. A face was not selected, and so the polygons are created on the
|
|
# workplane. Since the box was centered around the origin, the polygons end
|
|
# up being in the center of the box. This makes them cut from the center to
|
|
# the outside along the normal (positive direction).
|
|
# 6. The polygons are cut through all objects, starting at the center of the
|
|
# box/plate and going "downward" (opposite of normal) direction. Functions
|
|
# like cutBlind() assume a positive cut direction, but cutThruAll() assumes
|
|
# instead that the cut is made from a max direction and cuts downward from
|
|
# that max through all objects.
