Hi @kleerkoat,

Add a C# component that uses a SweepOneRail object.

Thanks Dale, this worked great. Couldn’t get it to work with stock components, but this worked first try. Thanks again!

You can offset the rail and use Swp2 instead of Swp1. Top view shows a slight difference with the C# version, don’t know which one is correct? Both ends look identical.

Or use Swp1 with PFrames aligned with Z vector (yellow group). This looks identical to the C# version, in top view and from every angle? It has an advantage in that each section can be rotated separately to create banked turns.
