Colision Shape help+Magos

Hey ive tried to put a colision cube on a model i made, but when i set the values and imported into world editor my model was still unclickable
and it dosnt render ingame unless the center origin is on screen
This is how to add this correct?

I used this set up
Vertex 1: -100, -100, -100
Vertex 2; 100, 100, 100
Colision BoX
im asumeing that this would make it when i click within 100 range of pivot point of this shape, it will select my unit?

ALSO if anyone knows what ones length Hight and Depth, id apreciate it

Im useing MAGOS\War3ModelEditor
