My ldraw import/export scripts for Blender can be used for part
editing, to a slight degree. It's lacking in edge functionality and
doesn't properly preserve comments currently. Since it was written
before Blender had the proper edge structures, perhaps that could be
improved, and comments could be tracked in a text. I used the script to
edit a couple of pieces before the bowtie winding fix was integrated.
The way it basically works now is that if you use it to import a piece,
it will load but not "flatten" that piece, so referring lines (such as
primitives or subparts) will be intact. Edges are nearly destroyed;
conditional lines will turn into "autosmooth" faces, and lines are
regenerated on export using only the active contrast colour.. I'm not
actually sure how that looks.
