| I was wondering, didn't see it discussed in the text, is it permitted / custom to have ldraw files in a mpd file reference other mpd files? If so is the first part in the file used or is there some naming convention pointing to the correctsubpart (...) (22 years ago, 5-Aug-02, to lugnet.cad.dev, lugnet.cad.dev.org.ldraw)
