The name is wrong.
This one is only missing 3 edges (or 7.5, if one compare it with a full prism).

We now have six different triangular prism primitives:
tri3.dat "Triangle 3"
tri3a1.dat "Triangular Prism with 3 Adjacent Faces without 1 Edge"
tri3u1.dat "Triangular Prism with 3 Faces without 1 Edge"
tri3a3.dat "Triangular Prism with 3 Adjacent Faces without 3 Edges"
tri3a4s.dat "Triangular Prism with 3 Adjacent Faces without 4 Edges Sloped"
tri4.dat "Triangular Prism with 4 Adjacent Faces"

There is no need for a double space in part name. It could never be more than 5 faces or 9 missing edges.

The word "adjacent" is not neccesary. The surfaces are allways adjacent.

We need to rename the original prism tri3.dat. It has 3 parallel surfaces.
Suggestion: "Triangular Prism with 3 Parallel Faces" Or is it not parallel?

If it's a triangular prism then it cannot have parallel faces...

A prism is a polyhedron, bounded by three or more planes (lateral surfaces),
whose intersections (Prisma side edges) are parallel, and the addition of two
floors (Prisma base surfaces), which are parallel.

OK, "3 parallel faces" is wrong here.
"Triangular Prism without Parallel Faces" or "Triangular Prism with 3 Lateral Faces?

3 or 4 missing edges? I guess that depends on perspective.
If you look at this as a whole, ignoring the slope, there are 3 missing on the top
and 1 on the side for a total of 4 missing edges.
However take into account the slope and the side edge is no longer in the prism
and therefore not necessarily missing leaving only the top 3 edges missing.

All I wanted was some sort of logic in how the tri-prims are named.
I won't hold this anymore now that tri3.dat is renamed.
