Marking object centers

The Center Mark tool divides an object or object face into quarters, marking the exact center of the object. This tool works for circles, ovals, rectangles, rounded rectangles, and faces of 3D objects that were created by a circular edge. In addition, it can place center marks on the corners of a rounded rectangle.

When the Center Mark tool is active, you can change the dimension standard for new dimensions created in the document from the Tool bar. To do so, select a standard from the Standard list, or select Custom Standards to create or manage custom dimensions (see Using custom dimension standards).
