Drawing cables with extrusion along path problem.

Hello,

First i will start with how i figured to draw cables in AECOsim building designer.

I draw with smart line arcs and line segments then i unite them with complex chain tool, after this step i draw a circle with my diameter and use the tool solid extrusion by path. It works great but i have some issues.

The main issue is that i have cables with 2 curves in the same plan (to be more precise i can will attach picture 1)

You can see that i have a curve by 2500mm radius from top to bottom, then another curve in the bottom plan again with 2500mm radius.

Here i have the cables that i cant do anymore:

How can i make those cables with those 2 curves by precise 2500mm radius on bottom plan and Bottom to top plan by exactly the same radius. (from the example in the picture 1)

Thank you,
