Create a Face from Non-Planar Wires

[CONNOR MORENO]

Hello!

Is it possible to create a face from non-planar wires in CadQuery? I have a collection of splines, connected by a straight line, that I would like to use to create a face (see the attached image for an example). However, it seems that the cadquery.Face.makeFromWires method works only for planar wires and I cannot seem to find an alternative method that works. My end goal is to create a solid from these collections of wires and my plan was to use these wires to define faces, then to define a shell, and ultimately a solid.

Thanks and please let me know if any clarification is needed!

Can interpPlate be made to work for your use case?

Hi Jeremy! Thanks for your quick response. I'm happy to give interpPlate a try! That said, can interpPlate be used with cadquery.Wire objects? The surf_edges parameter mentions that a "list of ordered or unordered wires" can be passed but when I try to pass my three wire objects, I receive the following error:

TypeError: Expected three floats, OCC gp_, or 3-tuple

Alternatively, when passing the coordinates used to define the wires to surf_edges, and coordinates at the midpoint between these edges to surf_pts, and using a thickness of zero,

face = cq.Solid.interpPlate(surface_edges, surface_pts, 0)

I receive the following error:
