bending the chassis
has any one thought of bending parts of the chassis rather than cut the angle and weld it

Actually I think most of the main manufacturers bend at least some of the parts

A bent chassis is a pre crashed one !
Imagine a triangle and how rigid it is, now put a bend on one side and its lost its strength, it will quickly collapse if loaded up.
If you want curves then retrict these to the body panels or you will weaken the car.

Bends are at the corners, not along the sides

I wouldn't have a problem with bends instead of corners. I have yet to see a roll cage made of straight bits welded together

But then how many cages have you seen made of 1" 16swg tube ?
There is a reason why the MSA calls for 2" CDS tube and restricts the circumference of the bend.

square tube isnt much good for bending , while retaining any of its strength/stiffness , compared to a triangulated structure
round tube is much better to use .

I considered making the botton rails out of one piece of tube, not bending as such but cutting appropriate Vs out of the tube and bending and welding
closed, if you get my drift.
Ended up doing it the traditional way.

Just as well the method you describe is a no go area from the fracture mechanics and fatigue view point.
