Aligning to Centerlines of Circles?

[jhh]

I'm trying to make a wall based light fixture that has an adjustable offset from the wall (because it will be used in a wall-based shelf unit). It is a circular fixture and I don't see how to align it to a reference plane. I've run across this problem before and just ignored it, but now I really need this to happen. How do you align an object with a curved (circular) surface?

turn on the Center Mark of the circle in the properties of the sketch line. The centermark can be aligned and locked.

Ok, that was too easy.....

Thanks!
