Hi;

I am trying to sweep a line (red color) along two rail curves (Orange and blue color) and it is not working. Any idea what is the problem?

thanks

Hi Sharif, Sweep cannot deal with a "Möbius strip" type layout of the rails and profiles, it expects a more simple structure that has the profile curve only at one "station" along the rails. Here you've got each rail touching the profile curve on different sides at the same time, that's not something that Sweep can deal with.

You might try dividing the rails up into halves and constructing your shape out of 2 halves rather than all in one single sweep.

Join the rails then sweep with a single rail with the flat option.
