I’m fielding at least 5-10 questions per day on the plugin (need to put up a FAQ). However, I thought this particular question on utilizing layers within the plugin was worth posting here:
Just to clarify, all pre-loaded layer names for all Plugins can be changed/modified through the global settling interface.
Can layer names be changed at anytime or must layer name changes be in place at the start of modeling? How would you update existing model layer naming to new names?
As mentioned in previous posts, editing or do anything to modify a wall panel (ie. adding a door or window) will cause the plugin to redraw the wall panel from scratch.
This is particularly advantageous for making layer modifications (changing a layer name).
Try it out, create a wall, then update the name for the framing layer (or any other layer name being used) to something different in the global settings.
Then regen the wall panel(s), ie. drop them down to 2D and bring them back up again into 3D. You will notice that the new layer name has been added and that the old layer name is also still present. If you have regenerated all of the wall panels then nothing should remain on the old layer unless you have manually placed something there, and you can safely delete it. SU will prompt you if something does remain and what action to take.
So the long answer to this question is that layer names can be changed at anytime and are not restricted to being set at the start of a model.
