# 1. Establishes a workplane that an object can be built on.
|
|
# 1a. Uses the X and Y origins to define the workplane, meaning that the
|
|
# positive Z direction is "up", and the negative Z direction is "down".
|
|
# 2. The highest(max) Z face is selected and a new workplane is created on it.
|
|
# 3. The new workplane is used to drill a hole through the block.
|
|
# 3a. The hole is automatically centered in the workplane.
|
|
# 4. The highest(max) Z face is selected and a new workplane is created on it.
|
|
# 5. A for-construction rectangle is created on the workplane based on the
|
|
# block's overall dimensions.
|
|
# 5a. For-construction objects are used only to place other geometry, they
|
|
# do not show up in the final displayed geometry.
|
|
# 6. The vertices of the rectangle (corners) are selected, and a counter-bored
|
|
# hole is placed at each of the vertices (all 4 of them at once).
