Hi,
I think I found a little bug.
When I use the command CIRCULARPATTERN OR -PATTER->CIRCULAR and enter the total number of items and the fill angle 360° I will also be asked to enter the angle between the items.
This schoud not be happen.

This only happens if you set Options -> Drawing Settings -> Unit System -> Base Angle -> Clockwise to TRUE.
If Clockwise is set to FALSE everything works as expected.
