curves wb, boundary to surface how to do

[Norus]

We created the boundary of a shape using curves wb. I couldn´t solve the triangle to surface problem (topic: mesh to surface, how to do?)

what´s the next step to get a surface. this surface is used as bottom and cover for a plate.

thank´s for help.

A test file would help.

Maybe you can switch to Surface workbench, use this joincurve as the boundary curve for a Filling surface, and add some vertex constraints inside the surface.
Or you can also try to generate a point-cloud object from the surface mesh and use the Reverse Engineering WB to approximate a surface on it.

thank you Chris_G, I will do that imedialy.

the file is attached

greetings, norus

IMHO, you should try to make InterpolationCurves (DetectAligned= true), 20 vertex each, then make a JoinCurve with all.
After that, try to use Filling feature?

Thank you, it works. -selecting the linepices of the border, ->change to curves - joincurve to create a spline -> surfaces, the first (borderlines) and the surface is done -> path - offset and the solid is created.

thank´s for your help.
