hey

as the subject says how can i create a body with a fixture thats perfektly 50 *2 ??

You can create a 'body with a square fixture', and then scale it. To scale in one dimension at a time, you can do S,X or S,Y. You can hold down Ctrl while scaling to make the scale change in discrete increments instead of smoothly. The context help panel (F9) will tell you what keys are available at each point in time. In the options dialog, you can change the increment size for the Ctrl key scaling, if the increments are too small.

thanks fore replaying

but i'm still finding it hard to make a perfekt 50*2 but i found the when im editing vertices i can make position for the giving point.
so i made my perfekt 50*2 square
