Hi Burr,

> There is some level of untrimming available, but you cant recover the surfaces from this fillet:

You can recover the entire surface on the piece on the left even if shrinking has been applied. If shrinking has been applied you can still recover a full cylinder surface for the piece on the right and that makes rebuilding the original result much easier since you can extend the cylinder surface just by editing its length or by stretching it.

Being able to recover big pieces of underlying geometry makes it a lot easier to do the reconstruction step, in your case here you basically don't have to do any drawing to create new parts, you've got a bunch of existing pieces that you can use.
