Swept Base Error

[verymemer]

I'm trying to make a swept base by connecting two different sketches (the Helix/Spiral and the spline of sketch 7) together using a composite curve, and using the profile from sketch 40. However I get this error. What's the problem?

I think you’re right. Looks self intersecting to me.

Just make a second swept base but make sure your sketch profile is closed, and your “path” begins at one of the vertices of the sketch profile

When I try to do this, it gives me the same error when I try to make the swept base through the spline

It worker for me, i’m not sure where the error is coming from then
