How to keep dimension lines off of part in a drawing?

Hi there,

I am currently making a few drawings for a project I am working on. I want to add a dimension to indicate a certain distance, but the orientation of the drawing is a bit odd.

I want to be able to insert a dimension to show the distance from the center of the cylinder on the right to the bottom of the large rectangle. However, I want to put the dimension on the right side of the part since that space is open. I can't figure out a way to make the dimension lines not intersect the part, since it looks quite sloppy. This is what it makes me do:

And this is what I want it to do:

Is there a way to remove the dimension line from intersecting all the way through the part horizontally?

Thanks!
