Creating a tetrahdron

[banksysan]

I thought this was going to be trivial.  I want to print a tetrahedron.

I've created the sketches, then created faces but cannot create the form as it's not valid.  The error says I should use the Repair tool, but it's not actually doing anything.

How do I make this sketch into a real, printable thing?

Loft to point.

(or Stitch patch surfaces)

Is the error message wrong then?  Using repair isn't the way to go?

When I try to switch to the Patch workspace I get the same error message.

Well, of course. Why would you try to model this in a T-Spline where you should be avoiding triangles ?

I'ts not that it could not be done, it just does not make a lot of sense, unless after creating the tetrahedron you want to modify the tetrahedron to take on a more curvy shape.

I that case, you can dissect each triangle into three quads.

Aye, if I really wanted a tetrahedron then loft would be better.  This is an exercise in learning Fusion & printing, hence wanting to use the tools correctly.

I have just used the create face tool again, but used quad and put two point on the same location  and then subdividing.

Seems odd that triangles aren't just converted to quads with only three unique coordinates though.

No, T-Spline. 2 sketches and a solid loft. Thats all you need.
