I recently moved from Solidworks to Inventor, and the transition has been a smooth one in all ways but one: Inventor does not have a width mate feature to aid with assembly. A width mate allows the user to center a part, feature or component equidistant between two edges or planes on a different part, feature or component, without the need to sketch and mate additional center planes. It is not the same as the current Symmetry feature, because Symmetry does not allow the user to select different faces on the same part, e.g. centering a clearance hole between the top and bottom edges of a slot in another part. I've linked to a YouTube video with a demonstration of the width feature below.

Of course there are other methods of centering assembly components that yield the same result, but those methods require opening individual parts and sketching new workplanes, or measuring then adding or subtracting diameters of slots or holes for an offset mate, etc. Adding a width mate feature would streamline workflows by eliminating these extra steps. This feature has been requested repeatedly for a decade now, as shown by the archived Inventor Forum post from 2011 and the Inventor Ideas post from 2013 linked below.

I sincerely hope this post can reach the developers so that this incredibly useful feature can be added as soon as possible. I also posted this request in the Inventor Forum for exposure.
