ShapeKind

Remarks

Doc 24's Creation table, and the last five entries are the point of it. Box, cylinder, cone, sphere, capsule, torus and plane are the shapes every engine ships; Stairs, Ramp, Arch, Pipe and DoorFrame are the ones that are tedious to build by hand, which is why Unreal ships a Stairs tool and why a blockout toolset that stopped at the seven would send a designer back to extruding a staircase one step at a time.

⚠ Deliberately not PrimitiveKind, and not an extension of it. That enum is Vixen.Rendering's and says which of the built-in meshes an entity draws — it is a four-byte value a thousand entities share one upload of, and its members are a file format the runtime reads. These have parameters, produce one mesh per entity, and are the editor's: a stair with ten steps and a stair with eleven are not the same geometry, so nothing about the sharing that makes PrimitiveKind worth having applies.
