Hi tptorpey, you recently wrote in moray.win:

Glad to see you made it here :-)

Moray is primarily a Constructive Solid Geometry modeller. Note the
'Solid' part :-) A triangle is not solid and so that's why some of the
suggestions (including mine) mentioned a translational sweep, which is
kind of a three dimensional triangle. Well, it starts out as a
quadrilateral, but if you delete one of the control points, it'll be a
triangle.

That said, you can work with a single triangle in the mesh editor.
Best way to do that is this:
Create > Plane
Edit > Convert To Mesh
Click on Edit tab at the top of the right sidebar
Go to Edge mode (press D)
Select any edge by Shift-dragging around a blue dot in the middle of
the edge.
Click on Split (under Edge operations), or Press S
Switch for Face mode (press F)
Shift-Select (hold Shift while clicking on them) the two smaller
triangles
Press Delete
Answer Yes to deleting the orphaned vertices.
Voila, triangle.

I realize this is a bit convoluted, just to get a triangle, but as I
mentioned Moray's modelling paradigm is not primarily based on a
triangle/mesh modeller.

Cheers,
