Scaling Custom Models

[Bakawun]

How do I scale custom models that I've imported? I'm on a Mac if it makes any difference (shouldn't but just saying). I am very comfortable with the editor but am weak with custom skins, models, and textures. I tried using the standard Art - Scaling Value, but to no avail. Please advise!

Thanks a lot, Bakawun

EDIT: I got 'em to scale (it was just glitching for some reason), but now I can't get the pathing size to change outside of the standard Pathing Map sizes. I can get 'em to change to those shapes, but I can't adjust the radius of them. Any suggestions?
