Creating a Bolt Circle

Select the Bolt Circle tool from the Annotation ribbon group in the Detail tab.
In your circular pattern design, click the face of your design that holds the pattern member to create a datum plane on which to place your Bolt circle.
SpaceClaim creates a datum plane for the Bolt circle.
Select a pattern member.

SpaceClaim automatically adds dimension call outs, arrows, and lines to the annotation plane. You can click an arrow or line to view or modify each dimension's values in the Properties panel.
