# SCRIPT NOTES:
|
|
# - Need test models for testing vertical faces scenarios. Currently, I think they will fail with rotation.
|
|
# - Need to group VERTICAL faces per axis_angle tag just like horizontal faces.
|
|
# Then, need to run each grouping through
|
|
# PathGeom.combineConnectedShapes(vertical) algorithm grouping
|
|
# - Need to add face boundbox analysis code to vertical axis_angle
|
|
# section to identify highest zMax for all faces included in group
|
|
# - Need to implement judgeStartDepth() within rotational depth calculations
|
|
# - FUTURE: Re-iterate PathAreaOp.py need to relocate rotational settings
|
|
# to Job setup, under Machine settings tab
