I've got a plate with a hex punch in it.

I used the polygon tool to sketch the hex in the part.

I would like to place a CL on the hex punch on the drawing on the plate.

How can this be done?

The usual Center Mark command does not work for this shape.

I also tried selecting one of the edges and selecting Midpoint - but that, as expected, only gave me the midpoint of the line ...not the hex punch.

Also, I need the CL to be associative to the punch in case i need to move the feature in the part.
