Sweep 2 generating invalid geometry

Hello everyone,

I am trying to generate solids with sweep 2 to make a solid difference with them after they are solids. But in this process grasshopper is retrieving me some invalid breps in the process. Anyone know how to turn around this situation?

A possible alternative.

I thought about the fillet edge but I am afraid that the edges numbering could be inconsistent whenever I open the file in another environment.

Although the rail revolution works like a charm, thank you!

You can filter the edge indices

with sort list?

No, next to the fillet edge component in the surface tab you’ll find a few different components which help filtering edge indices
