I’m new to Sketchup, and created already created my design, but now that I want to render using a different program, I need to assign layers so the other application can render individually. Anyway to assign a layer after you’vce already created something?
sure, create the desired layers and apply them to your entities/groups/components by “Window > Element Information > Layer”.
in SU layers should be understood as a ‘visibilty switch’, for structuring purposes use grouping instead.
I would say there is no other (right) way to assign layers. Use the entity info window to assign a layer to a group/component.
