I recently had a Bricksmith user write asking for help importing an LDraw file into LDD. (He was using LDraw because LDD made it very difficult to build his model.) But when he attempts to import the LDraw file, he sees at most the first brick of the model and nothing else.

I verified this on LDD 3.0.11 for Mac OS X. If I export an LDD file containing nothing but 2 1x1 bricks not touching each other, LDD produces a valid LDraw file. Attempting to import said file back into LDD (with no changes) doesn’t work. Sometimes I get only the first brick ready to place; sometimes I get nothing at all. In no instance do I get any error message; only the little import-finished bleep noise.

Is this a Mac-only thing? Is it a problem with the latest version? I can’t find any older versions available for download. My e-mail to Lego technical support hasn’t been answered yet either.

Thanks,

I’ve never had it properly confirmed but I’m fairly certain the problem with import is that the overlap detection is way too overzealous. Which means that when you read in a file it decides the parts conflict and can’t be there. It’s irritating.

This is the file that LDD exported:

0 exported
0 Author: LEGO Digital Designer 3.0
1 71 -190 -24 -190.0000152587890625 1 0 0 0 1 0 0 0 1 3005.dat
1 14 170 -24 210.0000152587890625 1 0 0 0 1 0 0 0 1 3005.dat

The two bricks are about 20 studs away from each other, so it’s hard to imagine how it could possibly see any overlap issues there. On import, I get absolutely nothing except the bleep sound. No bricks, no errors.
