Hallo,

I extruded the profil, but it was extruded flipped. What can I do that round side is on the outside of the roof.

Rail sweep seems to have caused the problem. By starting again with your 2d profiles and using 'Sweep' with Compound profile enabled has put the round part of the profile on the outside of the roof.

I used the regular Sweep with No Snap and it came out OK. I'm not sure why yours is reversed like that.

Yes, I´ve made it with rail sweep. When I use the sweep I think I must the profil first turn in a plane which is perpenticular to the startpoint of the spline.

When I use the rail sweep, it is automatically perpenticular but is unfortunately reversed. I tried to turne it with the mirror function, but the result was the same, perhabs there is another method.

That is correct. You can then control the orientation of the extrusion's cross section by rotating the profile.
