3D pick mode
In 3D Pick mode the Point 3D CoPilot catches to existing geometry elements.
If there is no existing geometry, the behavior of the CoPilot depends on the visibility of the workplane.
Active workplane is visible - The current cursor position is projected onto the workplane. Rectangular feedback indicates the position of the workplane and the position of the 3D point.
Active workplane not visible – The current cursor position is projected onto a virtual plane through the Point 3D CoPilot’s origin and normal to the viewport direction. Rectangular feedback always starts at the Point 3D CoPilot’s origin.
