mmm, I'm lost.
what you propose, if I correctly understood what you explained, is a faster method to manage a number of objects free from costrains of the around scene... that's right?
If so, I normally copy the Inline Canvas with it's objects and paste them in a new working file...
But, what I mean is like a partial transparency of lips up
tooths and the possibility to work with the Inline Canvas of tooths that are visually "under" the lips but fully manageable.
I imagine like a semi-transparent ghost image of the lips up the tooths that has no effects on the objects under, it's only like a slide on my glasses...
PS.: I can't put no objects under a Paste Canvas
, I don't know how it works... maybe...
Tooths remain at the same level of the PC
