i meant normally you could do it in the side bar?? now i just move my whole brush lol

and does anyone have an idea why the option make structure won't work??

1) Brushes: Select the brush you want to manipulate. In the 2D window, left click INSIDE the brush and hold the button down.. you can now move the brush
leftclick OUTSIDE the brush and you can alter the height, width or depth (depending on where you click and which viewplane you're in.

2) Brushes are structural by default.

so everytime i make a brush i need to deselect it instead of the make structural option??

Depends on what you want to do with it.. but yes, you don't have to make the brush structural yourself, because it already is.
