Here's the use case. In the attached part:
1) Look at the "Thin Panel" sketch. The clearance circle needs to be aligned with the double D round shape. As with the other 2 openings on the sketch, I want to project a reference sketch to use for alignement. However, since the double D can't have maintain association, I have to reapply the same dimensioning used on the original double D sketch.
2) On the "Fan Hole Pattern", I would like to use a Round Pattern figure to easily position the holes, but I have the same problem with the project to sketch later when using the fan holes to align the obround vents in the "Fan Vent Slots" sketch. I would also like to copy paste one fan hole pattern and paste it for the second fan hole pattern. Then a single fan spacing dimension would align the 2 sets of fan holes.
It's not that I can't accomplish the same end result, it's that it would be so much easier, and less prone to errors later on with edits, if they could be referenced with maintain association.
