Hi!

I’ve been trying to made a loft between two sections and so far i can’t. Can anyone please indicate me a workaround?

Thanks!

Hi Marques,

What method did you use to generate your curves?

Problem solved, thanks

Hi

I am having similar problems. I’m using Rhynamo to import the outline geometry. The polycurves are all pointing in the same direction, closed, etc but I am getting the same error:

Error : Warning: Solid.ByLoft operation failed.

Unable to loft! : BAD_UV_SKIN_DIR — Surface U and V derivatives are in the same or opposite direction

 

I’ve rebuilt the polycurve by extracting each sub curve, getting its start point and then creating a new polycurve by points by the problem persists. Any suggestions?

@Aparajit_Pratap is it possible to shed some light on what this error message means for people in this thread ?

[Aparajit_Pratap]

@danail.momchilov can you share the graph for us to take a look at exactly what is failing and why?

Hi,
I met with the same error message yesterday. After reading some other posts, I found there a solution for my problem. I put a List.Transpose node right before the Surface.ByLoft node and now it works well.
