Hey all,
I use projected sketches a lot, but I am not a big fan of the feature as I find it pesky to deal with so far.
I think it would be awesome if we could (1) project a sketch/geometry, and then (2) erase the projection attributes.
In other words, transform purple lines to clean blue ones forgetting the generating ties.
The way I get around it now is by re-drawing on top of purple lines - buts it's messy.
I apologize if this feature sits undiscovered by me - or if I am misusing a well-made attribute...!
