Flipping Mapmodels on the Z Axis

[Invalidd]

Instead of rotating the models to the left and right, is it possible to rotate them up and around (kind of like what you can do if you rotate blocks by pressing CTRL+R). If not, is there a way I can edit the model's file so it appears flipped in a direction I would want? If not, I won't hesitate to use a program such as Blender to manually flip the model itself, but even then I may need a little input on how to do so. It'd be great if I could get some help on this.

sandbox already does it on the Z axis

what you're describing is either the rotation on the X axis or the Y axis; neither of which can be set in the mapmodel entities
you can try using mdlpitch in the respective model before using blender to flip it

Alright. So far Blender seems to be having problems opening an MD3 file. (I'm editing one of the default models from sandbox) MD3 isn't even on the list of imports. Now I do have the scripts in there for exporting the MD3 files (though I could never get it to work), so I'm not sure how I should go about loading a MD3 file in blender.

You might have the script in the wrong blender folder. "There's a hidden one"
