Hi Paul, welcome to the forum!

re: select adjacent 2D curves - right now I'm not aware of any existing script to do that. That's probably something that I'd want to add into the main MoI program instead of in a script since it would need to look through the entire model which could possibly be slow on complex models.

re: DXF layers, MoI does support writing styles as layers for DXF export, but currently not for DXF import. That's something I can tune up in v4.
