Saves all materials in model to external file so they can be added to another model. Useful to get all materials from master model into sub models for smaller parts.
Eneroth Material Extractor

When adding parts drawn in seperate models to a master model you easily end up with duplicated materials because you created a new material in the sub model even though a similar one existed in the master model.

This plugin finds all materials in a model and save them as a Sketchup file that can be copied into a sub model to get the same material palette there.

Run from Plugins > Extract Materials.

Known Issues

A component definitition with all the materials will be kept. This can be removed by purging components.
