Hi,

Could someone explain me all the differences between .ldr and .mpd ?


Thanks in advance for your help,

LDR is an individual model file. MPD is a file that contains many LDR file. Basically MPDs make it easier to share a model that is made up of many files by rolling all those file into one large file.

P.S. Moving this topic to the Help forum

From a software authorship perspective, there is no difference between files with the extensions .mpd, .ldr, and .dat. They are all valid LDraw files, per the specification, and they all might contain multiple submodels.

Historically, MLCad has saved files containing multiple submodels (MPDs) with a .mpd extension, and files with a single model under a .ldr extension. Bricksmith on the Mac has always created all new files with a .ldr extension. Both editors ignore the extension when opening files.
