In previous versions of SolidWorks (I'm using 2016), there was a sldprt feature allowing the user to "click/select" any features' face in the window; any correlating part sketches would then appear, as well as "preview sketch dimensions" (greyed-out). It would then allow you to adjust any correlating dimensions without actually having to enter into an "edit sketch".

As of right now, I can show all feature dimensions permanently, but this becomes very crowded with dimensions while working on complex parts. I'm looking for a "dimension preview" feature, for lack of a better term. Thank you for your help!
