# 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. Draws a line from the origin to an X position of the plate's width.
|
|
# 2a. The starting point of a 2D drawing like this will be at the center of the
|
|
# workplane (0, 0) unless the moveTo() function moves the starting point.
|
|
# 3. A line is drawn from the last position straight up in the Y direction
|
|
# 1.0 millimeters.
|
|
# 4. An arc is drawn from the last point, through point (1.0, 1.5) which is
|
|
# half-way back to the origin in the X direction and 0.5 mm above where
|
|
# the last line ended at. The arc then ends at (0.0, 1.0), which is 1.0 mm
|
|
# above (in the Y direction) where our first line started from.
|
|
# 5. close() is called to automatically draw the last line for us and close
|
|
# the sketch so that it can be extruded.
|
|
# 5a. Without the close(), the 2D sketch will be left open and the extrude
|
|
# operation will provide unpredictable results.
|
|
# 6. The 2D sketch is extruded into a solid object of the specified thickness.
