Is there an actual, logical reason you can't select things on the Linework layers and copy them? Is there a way around this? (Aside form duplicating the layer and erasing what I don't need.)
You can. Hold shift while on the pen tool to draw a rectangle that selects 'spots'. Those you can copy as vectors (ctrl-c, crtl-v)
Else you can ctrl-a to select all, and paste as a drawn layer (not vector)
Else you can ctrl-a to select all, and paste as a drawn layer (not vector)
Remember to try the other way, so you can still edit them as vectors! :3
