Hello all

I'm building a skid and placing different components (mostly cylindrical) onto it in an assembely. They need to be in exact locations on the skid, to do that so far i've been making parts (that have the length and height and a circular end) to get locations on the skid for the real parts that need to be placed on it. Is there a way to put a part on another part x distance from this side and x distance from another? Here's a picture to explain how i've been doing it. I feel like there's an easier way but can't figure it out. Thanks in advance for any help that can be offered.

Why don't you just use distance mates?
