StudioMDL (Source)

It has been suggested that this article or section be merged into Compiling a model. (Discuss)

Studiomdl is the command-line tool used to compile models from the intermediate Studio Model Data format exported from modeling packages to the binary .mdl format that is read by the Source engine.

It can be found at steam/steamapps/<account>/sourcesdk/bin/[orangebox|ep1]/bin/studiomdl.exe.

Studiomdl is executed with a QC file as a parameter. For more information about compiling, see Compiling a model.
