 | | Large LDraw/MPD Files?
|
|
Has anyone had experience with HUGE LDraw files or MPD files (thousands of parts)? What are the effects? Do they crash some programs, or make them unusably slow? Just curious. Thanks! -Tim (22 years ago, 20-Dec-02, to lugnet.cad)

(...) What are you trying to view the file with? MLCAD has a hard time when the files get too big even if it is a file with multiple-sub models. Forget about LDView it will hog up memory like crazy trying to turn the model. -Ahui (22 years ago, 20-Dec-02, to lugnet.cad)

(...) As with most large files, the limitation is generally not the program but the amount of memory on your system and the size limit on your virtual memory. -Orion (22 years ago, 20-Dec-02, to lugnet.cad)

(...) Datsville is IMHO a HUGE model, with its 2Mb+ and several sub-models used multiple times. MLCAD is out of the question, but L3Lab is acceptable: 6.3-13 seconds, depending on zoom factor and other preferences. No problem with L3P, but I haven't (...) (22 years ago, 20-Dec-02, to lugnet.cad)

(...) Dumb question... but where is Datsville hosted right now, and who maintains it? There should be a link on LDraw.org, but there isn't to my knowledge. I'll fix that on a long overdue wave of updates sometime in the relative near future. Thanks! (...) (22 years ago, 20-Dec-02, to lugnet.cad)

(...) Why is it that MLCad isn't appropriate for large models? Does it take a long time, or will MLCad actually crash? And what is the size limitation? I'm working on a fairly large model - well, it has a large number of parts, though its overall (...) (22 years ago, 20-Dec-02, to lugnet.cad)

(...) I'm not sure what you mean by this. Ldglite only creates one structure in memory per part file. It's quite frugal with the memory when you use the L3 Parser. Thanks, Lars. I think I've displayed datsville in ldglite on a PC with as little as (...) (22 years ago, 20-Dec-02, to lugnet.cad)

(...) I meant basically what you just said. Ldglite doesn't create a new copy of the part each time it is used; LDView does. I do this for various reasons, but I believe that when I go back and revisit those reasons now with the advantage of (...) (22 years ago, 21-Dec-02, to lugnet.cad, lugnet.cad.dev)

You can get MLCAD's response time on refreshes to be much snappier by reducing the size of the 3D window. The isometrics don't take much processing power, even with large numbers of pieces. Also try running it under Win2k with lots'a ram. Win 98 (...) (22 years ago, 21-Dec-02, to lugnet.cad)

I'd love to upgrade the HD too...20 GB just ain't enough for my MP3 usage ;-) I've (...) (22 years ago, 21-Dec-02, to lugnet.cad, lugnet.off-topic.geek)

Hi Tim, I've been working on a model with lots of synthesized pneumatic hoses, and it is about 16M (it qualifies as large). I found that LPub didn't handle this well at all. It would not choke, but it took a very long time. I tracked it down to (...) (22 years ago, 5-Jan-03, to lugnet.cad)
