That saves a lot of time itself, but here\u2019s the cool part. Both objects are associative. So, if you move the circle, the center mark goes with it. Edit its shape, and the center mark adjusts to the new size. The centerline does the same thing.<\/p>\n\n\n\n<p>Consider this scenario (which I\u2019m sure has never happened). You\u2019ve designed a plate with a couple of dozen 1\/4\u201d holes in it. The design criteria changes and all those holes are now 3\/8\u201d.
