The extents of a M2 seems to be calculated from collision box, bounding box and rotation

It's also possible that my calculation of the selection box is wrong but i kinda doubt that atm. At least i don't see what i could go wrong there. I basically just use mouse pos in world of start drag position to mouse pos in world of end drag position and calculate the box out of that with the min and max values

Hm wouldn't that only work properly from being perfectly above ?

Kinda but i don't really know how you would limit that in a full 3d environment

X y cords dont' translate very well from a 3d view, I'm not a graphics specialist but there are other methods for 3d views for sure
