# Where is studiomdl.exe?

All the places I’ve checked say under /sourcesdk/bin/orangebox (etc). I’ve tried to look for studiomdl.exe, but in my %name% folder there are two folders: source sdk base, and source sdk base 2007. In neither of their \bin folders are any folders called “orangebox”, each file in it is a .dll. Can someone help me find it?
