[Code] layers.purge_unused

[daiku]

Have you tried manually making the problem layers invisible? If so, does anything disappear? Also, try manually deleting the layer. If it's truly empty, SU will quietly remove it. If it's not empty, SU will warn you, and ask where you want to move the things. CB.

Can you supply the model you are working with? It might help figure it out faster.

Thanks all. I need to rethink this before asking people to venture further down a blind alley.

I can reduce a Sketchup up model to two plain text lists. One lists components and groups and the other lists scenes. Both lists are turned into javascript multi-level arrays.

But I don't want to wipe out any established relationships between components and layers, layers and scenes, scenes and styles and scenes and property settings. I thought I could do that by manipulating the model but I am thinking it is probably better to capture the data and regenerate the whole thing.

If you are interested in why I want to do this please see the discussion in the Modelur thread.

Thanks and regards

Chris
