Hi guys,

I am trying to extrude the 2 profiles having 2 rails but the extrusion direction might be an issue? the direction of extrusion looks like it is twisting? any idea? thanks

try to reverse / flip direction of one of the sections.

Hi Tom,

Thanks for your help, yes, I did used the flipping curve, but I think the issue is the order of points of the two profiles need to match-up so that it will extrude on a correct direction. Please refer to attached files below, cheers.
