.STL Mesh to PCBway CNC Manufacturing format

[cellcreator]

Hello,

I am trying to make a small part using PCBWay CNC Manufacturing. The part has been designed in TinkerCad
and exported as a .STL file. Using FreeCAD I converted the part into a solid and exported into .STEP format.



After I uploaded the part to PCBway and paid the fee, I receive an email telling me that they cannot manufacture it
and that they need a version without any triangles.

Is there a way to convert this object to one without any triangles and export it to .STEP format?

Thanks in advance.

Automated conversion is only pretty good at best: fusion, rhino, viacad/shark all kind of do it. Good for complex surfaces that you need to get starting point editable surface.

For a simple shape like posted just remodel it in a cad that does nurbs/surfaces. Meshes are for video games and 3d printers.

So, you mean it cannot be done from .STL?
Thanks.

You’ve spent more time posting here about this than it would take to model that on decent software. Looks to be a quick cross-section sketch and then a revolve and done.

I'll model it up for you if you send over your dimensions and the STL. One thing I think I'm seeing are threads terminating into the shoulder. You'll want a thread relief there. Can you let us know what this part is mating with?
