James Kincaid Hello,
SpaceClaim has limitations in normal unit space. If you switch to a small unit space like nanometers etc, it will allow you to make small changes, and geometry edits. To get to small unit space, close all open windows/designs in SpaceClaim, then go to File > SpaceClaim Options > units, and then you will be able to access nanometers. To bring in the existing geometry, you will need to use the Assembly tab > Insert file tool. (trying to open a normal unit space model in small unit space SC will not work).
