how to give correct dimension in sheet metal drawing?

I m having problem in certain sheet metal part, I have attached it.

The problem is the middle bend (the one with 145 degree). I tried almost all methods there are like changing dimension style, Changing k factor or bend radius .

the total length after bending is always different (ether plus or minus). So please anyone can tell me what i m doing wrong, and steer in right direction.

sorry for my bad English
