Have you ever been working on an assembly in Autodesk Inventor where you want to apply a mate constraint but you can’t see the face you want to mate to? This tip will show you an easy way to pick the face without having to rotate the view or part.
When using the Constraint command, switch to the Flush option. This makes it much easier to select the faces you want. Then once you have the faces you need, you can switch back to the mate option. This works well in a crowded area of an assembly.
