something is messed up with the measurements i put in for the radius of the die.
If the initial calibration of your program isn't set up properly for the tube/die/CLR size you'll have problems. Do you have the operators manual that came with the program? the calibration procedure starts on page 20, its kinda confusing I suggest calling Cris @ 20/20 ( 651-257-8715 )or get ahold of him (fabcam) on pirate, awesome guy and will get you set up quickly.
I use bendtech on most everything I build unless its a simple hoop that I don't need a specific length like if I just need the bend and am going to cut the straights to fit (upper coilover hoops etc) For multi plane bends its great with bend locations, rotations, angle of bends and cut lengths. Another thing that helps (me) is it gives you cut length, in other words, it calcs all the bend lengths in each bend (which is a major PITA to figure yourself especially in multi bend pieces) and gives you the overall cut length of tube to start with to make your piece. It will pay for itself in tube not wasted.
I got BT-EZ 3D when it first came out and Pro has since been released and will eventually get Pro when I toob out the cab/front end of my pile. Looks really sweet with being able to build multiple pieces (entire chassis, bumpers etc) AND gives you the cope angles for each piece @ each junction !
