How to model slideway ( twist guide for the aluminium cans) in SolidWorks.

My problem is to model slideway for empty cans. Main problem is in round bars.

I need to have good models of bars for CNC bending bars machine.

I tryied to use a combination of:

loft - when bars goes only in Radious
loft with twist along the path - when can is rotated along the path.

But it do not looks good- i obtain not smooth regular shape.

What operations i should use in solidworks to make it in the proffesional way.

The can inside do not may to stock- so the profile along the path shall be always the same.
I'm adding the pictures of oryginal guide which i must modydi for inner can.
and my test-sample creenshots with bad method of modeling(not smooth shape)

Why don't you try using composite curve. After making the path that consists of several lines use composite
curve to create one path and than use the sweep.

howzit gave it a bash
you can controle spline pretty well with sketch points
try this
you get vey good control

Ok guys! Thanks a lot for your sugestions.
Finaly i did the smooth shape with "parrallel" bars among all the path with loft operation.
I lofted - Two round profliles and give the moddle path (3d sketch - splajn with only one point to control -which i fixed into auxiliary sketch, begining and the end tangent to existing bars.
