Subject: [CR]Determining twisting of main frame tubes

Hello,

Can anyone help with a method to determine if the main frame tubes are in one plane, or if they are twisted out of the plane, for instance after a side collision. Also, what is a good method to straighten the frame. My problem is that it is difficult to control the force and not overdo the straightening.

Thanks for your help
