Yes, there are various ways of creating hole circular hole patterns.
In CAD select Circle and use the Properties button to set the size, then from the Main menu choose Draw > Repeat operation. Here you can select the radio button "Repeat around arc to be defined below", this allows a full or partial arc to be defiend with any number of holes and also the ability to set the start angle of the first hole.
Then create a pattern as normal.
In CAM - much easier unless you need the PCD to be part of the drawing.
From the bottom toolbar choose the Pattern Icon and set the details as required, then Define and Select a tool, then choose the Drill icon and drill the holes. OR - from the Level 2 (standard menu) from the right hand side of the screen - if not visible selet the Command tab - then choose Drill, Ream,Tap icon and set all the details in a single operation.
Hope this is clear.
