Thanks again for the test models guys, helped bunches. I've got all the data in correctly for all the test cases. Or as Jim would say... "Is everybody in? The ceremony is about to begin..."
I might get serious on this tonight and try and get the models built. That should be the fun part. Another look at marstone's blender 2.4 version should help. (and the stock lwo and 3ds imports...)
the data import (may need tidying up as I build the model... its simple enough not to need its own classes and object oriented design... I think I can get away with a one, two procedural punch for this task):
