Hi,

I have a train model and created 2D views. Now I apply some color design curves to the train and like to create 2D curves of this design curves only without all the other curves again. Is there a way?

Ciao,
Micha

Hm, make 2D of all, then lay on top of old and selDup?

Or put new curves on a separate layer, then let make2D put 2D curves on parent layer instead of the “2D layers”.

Then SelLast, turn off “new layer”, delete, turn on “new layer” selLast.
