two best ways to inspect an intersection:
3D sketch--make an intersection curve by selecting suspect bodies
You might consider adding some reference geometry into your assembly, from the "insert" menu (plane, axis, or point). You can then use that to create further reference geometry if needed, or measure from there when you have enough information.
Thanks guys! I will try these ideas out. In the past I have added planes and\or sketch geometry but sometimes the models are not as simple to add more geometry, plus it takes time away from what I need to be doing... let me ask you this, don't you think that the measure tool should be able to determine that information already by my selections, especially since all the information is already there? I specified X,Y,Z as my measuring from location. I just don't see how this tool doesn't give better feedback than what is shown above without me having to add extra data just to get a basic measurement.
I know this will be an ER, but with all the hip over the years about the changes in measure tool, they forgot this one.
