The calculation based on drilling points is a very basic drill cycle. It works without any machining surfaces. Drill positions and orientations will be defined either with points or lines.
On surface - with points/lines on the surface, the user must select points/lines that are positioned directly on the surface. The orientation of the tool axis is determined by the surface normal.
Points - For this cycle, the user must select points from the geometry. The drill cycle starts at the selected points. The orientation must be set up on the Tool axis control tab.
Lines - For this cycle, the user must select lines from the geometry. The lines define the position and orientation of the tool as well as the drill depth.
