Sweep 2 Rails not working as expected

Hello everyone,

I am having trouble with the sweep 2 rails command. I am trying to sweep curve 1 across curves 2 and 3. 

Curve nr 3 was at some point split and rebuilt. I couldn't get the sweep command to work, so I did the same operation on curve nr 2, hoping to get it to be defined in the same way as curve nr 3. The sweep command still didn't work. I then tried reparametrizing and flipping the curves (brainlessly, by trial and error), and still no combination worked.

Baking the curves in Rhino and trying the sweep 2 command there produced the same wild results.

Any ideas?

Hello Tom

Thanks for the quick reply.

I realised that I obtained curve 3 by projecting curve 2 on a very dense network surface, so that's where the control points come from.

I got the sweep to work by rebuilding curve3 and then breaking the rails into two parts.

Thanks for the advice!
