Creating center marks

Center marks can be added to a circle or arc, for example, marking a hole in a mechanical part. When you move or resize the associated entity, the center mark entity also moves or resizes.

To create a center mark

   1   Do one of the following to choose Center Mark ():     

    On the ribbon, choose Annotate > Center Mark (in Center Lines).

    On the menu, choose Dimensions > Center Mark.

    On the Dimensioning toolbar, click the Center Mark tool.

    Type centermark and then press Enter.    

   2   Select the circle or arc that you want to add a center mark to.

   3   Continue to select circles or arcs, or press Enter to end the command.

You can change the appearance of center marks.
To change the appearance of existing center marks, use the Properties pane or grips. To change the appearance of new center marks, before you draw them modify the CENTERCROSSSIZE, CENTERCROSSGAP, CENTEREXE, CENTERLTYPE, CENTERLTSCALE, and CENTERMARKEXE system variable values.
