Hi all,
I recently found this post on the Eurobricks website:
http://www.eurobricks.com/forum/index.php?showtopic=41226
Here you can find a huge list of Lego sets that are available in LDD format. It
was interesting to note that many of the sets are missing certain pieces (mainly
sticker parts and minifig parts) - this appears to be the same problem for sets
constructed using LDraw tools (MLCad etc).
I converted some of the LDD files into LDR files using the export option from
LDD. This appears to use XML file (LDraw.XML) to translate the LDD parts to
LDraw parts. How often is this file updated? I found this website that appears
to have a more recent version of this file:
http://gallaghersart.com/site/page/new_ldd_parts_and_the_ldraw.xml
This got me thinking...which has the most parts LDD or LDraw? Are the parts in
the two libraries copied/borrowed/derived from each other? How closely are the
LDraw community working with the LDD team?
I would be interested to hear your comments
Reuben

I'm pretty sure LDD has way more parts, patterns being a possible exception.
Many LDraw parts that have been developed more recently were done so with the
gracious help of the Lego Universe Team, who did us the favor of converting
batches of parts from LDD to LDraw format. The files they provide are starters
and need further cleanup by part authors. There hasn't been a new batch since
the 4th one, which was back in September, probably because Lego Universe went
online in October and they've been busy with that.
Recently Philo posted instructions in this group on how to use a 3D screen
grabber, which I guess is intercepting DirectX commands, to grab parts directly
out of LDD. With a little reorientation and rotation, these files are basically
identical to the ones that the LUT provided to us except that they lack even the
most basic edge lines--they're very raw. I've been working a bit on the
long-needed farmer's cowl myself using this technique.
Cleaning up a part can be a lot of work because it involves primitive
substitution at the very least, but it usually also means changing
circular/cylindrical/spherical pieces to use 16 edge segments instead of 12,
adding missing detail, or even sometimes correcting a stray vertex or flipping
triangles around. The first part I ever did from a batch of LUT parts was
44358.dat; it definitely needed some vertex corrections but it was pretty close
to what it needed to be. Hair and hat pieces tend to be much harder to cleanup.
But these parts converted from LDD have been a godsend to the community because
they give part authors a starting point for pieces that are otherwise too
complex to model.
This doesn't go the other way as far as I know. I'm not aware of any LDD parts
being based on preexisting LDraw versions.

Hmm, and I am sure that LDraw has more though (correct me if I am wrong or prove
otherwise).
I mean, take all old parts that _are_ in LDraw and _not_ in LDD.
Take the color availability in to account, and there you go.
If I'd model my designs in LDD I won't be able to complete any one of them just
because the parts I use are not in LDD or if they are not in the color I have.
Just my 2 cts.

The newer versions have a free build mode with all parts available in all
colours.
I'd guess that LDraw has many more non-minifig parts but LDD may pip it now for
total due to the proliferation of minifig parts.

OK, but that rules out parts that were in before that have been removed. I
recently opened an old LDD file which was complete, but is now incomplete due to
lack of parts.
Also correct models opened in free build mode give incorrect colors sometimes.
For me as an LDraw fanatic LDD s***s. Though I must say I do use it from time to
time and going to use it again now that I know the import and export functions
have been restored.

I am glad import function for LDraw in LDD has been restored.
For me it didn't work a while.
Pitty not all parts are in and parts that are in LDD get removed now and then.

An estimation made by JC Tchang gives 2433 parts for LDD and 4506 for LDraw.
These figures include patterned parts, but not the 550 LDraw shortcut parts.
