 | | Large LDraw/MPD Files? —Tim Courtney
|
| | | 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)

| | | | | | (...) 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 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)

| | | | | (...) 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 (...)

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)

| | | | | | | | 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)
