Sweep1 not working

Hi all,

I am new to Grasshopper and I am trying to create a parametric truss, but Sweep1 is not working with my current geometry. I have read in similar posts that adjusting the starting point of the rail curve solves this issue, but I might be doing it wrong as it is not working. Any help would be appreciated, thanks in advance!

Apart from the parameter not being calculated correctly in your definition, but still giving the correct value, the method used is fine. The problem I think comes from the sharp edge of the sweep that Rhino can’t compute.

I rotated the shape 180 degrees so it would work with the intended size.

Thank you! It is indeed working fine with all the inputs now.
