How to Extrude a Helix with an Even Surface in Archicad?

[Edo0629]

Hi everyone,
I'm trying to extrude a helix by 5 cm in Archicad, but I'm running into an issue. The extrusion creates an uneven surface, and I haven’t been able to find a solution to make it smooth or uniform.

Is there a tool or technique in Archicad that can help me extrude the helix while keeping the surface even? Any suggestions would be greatly appreciated.

Hi Edo

Try the curved ramp object in the library... That should do the trick.
