object snaps for push/pull and extrude

[Anonymous]

when using PUSH/PULL in Sketchup it is always looking for a snap point or edge.  I am not seeing this at all with Fusion.  perhaps my settings aren't correct.  all the tutorials seem to be dimension based.  if I push a face back and want it to, say, be flush with an adjacent face it appears that I must either already know the exact displacement or simply eyeball it.  is this true?

Start pushing or pulling then pick the face you want to be flush with. With extrude under extents there's an option "To".
