Lofting transformation triangles to circles

[cthom27]

I’ve been unsuccessful in lofting the transformations from triangle to circle on my tetrahedron.
Neither ‘ruled surface’ nor ‘loft’ works as I would expect, and the result is a twisted mess.
What am I doing wrong?

Thanks in advance for any help…

Looks like the circles and triangles are going in opposite directions. I don’t have LunchBox so I didn’t open the file, but you can try flipping the circle direction, or rotating the circles until they align better with the triangles.

Take a look at the attachment.

Thanks for your reply David, curiously flipping only fixed one leg and left the others messy.

Thanks to you also HS_Kim. As a Grasshopper beginner it’s going to take me a while to figure out what you have done to fix the problem!

Have you tried creating the shape in Rhino? How familar are you with Rhino?

Slightly better than previous posting?..

Seam alignment is a common loft/ruled surface issue. If you would like, Pufferfish plug-in has an “Align Curve Seams” component that will auto align them for good results.

Your problem has been solved many times already, just posting another one because I spent the last 15 minutes trying to solve it

Thanks to everyone for taking the time and trouble to sort out my problem.
Very much appreciated, now I just have to figure out how you did it!
