Does anyone know why this loft isn’t working? Please let me know. [Screenshot 2026-04-25 at 10.25.34 AM]

curves must be in a list flatten the curves input of the loft

i added a flatten tree between the extrusion and the loft and it still failed. is there anything else you would advise?

After flattening the list of input curves you have to add them to Loft in increasing (or decreasing) order - bottom to top, front to back etc.

[Screenshot 2026-04-25 at 21.37.24] What you do here doesn’t make a lot of sense to me. Why do you provide extruded surfaces to the Loft component? It expends expects curves!

I was trying to create horizontal pipes or surfaces in that circle. Do you know how else i can do this?
