Base displacement from the copy base point to the current cursor position
One-based copy index (1 for the first copy, 2 for the
second, and so on)
Total number of copies in the array preview
When true, scales by factor / copyCount; otherwise
scales by factor
Scaled displacement as a new AcGePoint3d
Scales a copy preview displacement for one array index.
Computes the world-space offset for copy factor
factoralong a COPY array preview. In fit mode, displacements are distributed evenly between the base point and the cursor so the final copy reaches the cursor exactly.
