Hello dias_ryan,

Welcome to the 3DCADTips Inventor Forum!

In Inventor 11 while in the assembly, select Tools > Measure Distance and select the two components. Use the pick filter to select sub-assemblies, parts or faces. A preview line representing the distance measured is displayed. You will need geometry to select to measure from. If you don't have the desired location to select, you'll have to create it in each part.

Good luck!
