I hope this isn't off topic for this list. I've begun writing some scripts
for Blender to import (and eventually export) LDraw DAT files.
Cropped screenshot of result (pieces 105, 10 and 73057):

Script location (currently 5KB):
http://donkey.dyndns.org/~yann/datimport.py
Blender:
http://www.blender3d.org/
Supported features:
Loads DAT format, parsing line types:
0 STEP Uses layers to make objects appear frame by frame. All objects
start on layer 1 and are added to layer 2 as well at their step.
1 Inclusions. For the directly loaded model, these will be separate
objects. Included models will be merged into a single mesh each.
3,4 Faces.
Unsupported features:
MPD Easy enough to implement, but I haven't done it.
Colours Somewhat trickier. Currently no material assignments are done.
Model types Eventually should identify pieces vs primitives, and not
merge submodels. Pieces should be merged for models, but not
if loaded individually for piece editing.
Pre-converted libraries (relatively easy to do using scenes)
Exporting I'll have to write this, too. Don't expect automated
detection of primitives, but references will work.
Any comments?

However, I'm having some problems, hopefully you can help me out? I try to import ldrs and (...) (20 years ago, 12-Aug-04, to lugnet.cad.dev)

Recent additions: * Requires Blender 2.34 for some convenient functions. * Creates materials for each LDraw colour used, but does not fill in colours. * ldrawdir is now high in the script and (...)

| A little bit of extra work, and I'm ready (sort of) to present the first export capable edition. It outputs DAT or MPD files of the current scene, including STEP support.

| I added a feature to automatically generate contour lines for exported objects, and reexported my 6575 model. I'm not sure it's quite the way it should be yet. Also set up a wiki page where I'd appreciate suggestions and questions. The wiki will be (...) (20 years ago, 2-Sep-04, to lugnet.cad.dev)
