Hello,
I’m facing an issue with the Sweep1. I’ve already internalised the curves, Thank you in advance for your assistance.

Graft both the ‘Rail’ and ‘Sections’ inputs to Sweep1.
But the sections appear to be aligned incorrectly?

Thanks Joseph!
Rails duplicated?
Difficult to be sure because your section curve is so small relative to your ‘Base_Curve’ but this might be better? There are other ways…

P.S. Your original code was more messed up than I realized. In addition to the alignment issue, the ‘Mullions’ (Sweep1 results) are each only one story tall. Is that what you want?
They aren’t well organized either. You must understand data trees 
This version does that.

P.S. By the way, this is a poor example of Sweep1 because the rails are straight.
