I need to figure out the angle between these two faces to see what range of motion hinge is needed. How do i do this?
Add a layout sketch in the top level and use construction lines to lay out your desired motion.
You can mate your parts to the layout sketch. Use angular dimensions in the layout sketch to drive the motion between parts.
Anna i tried that and it only gives me the distance between the two faces
Check my response, I edited it. If only a distance is showing it is because the planes are parallel.
