Is there an API to inject raw triangle mesh data into a Creo part, or must we use file-based STL/3MF import or build BREP via ProIntfData?

Hello Creo API team,

We are building a Creo Plugin . We already have tessellation data in memory:

• Vertex coordinates (x, y, z)
• Triangle connectivity (facet index list)
• Optional normals

Can we create faceted/mesh geometry in a Creo part from this data programmatically (no UI)?

Specifically: Is there a public ProToolkit API to create mesh geometry directly from in-memory vertex + triangle buffers (similar to passing a vertex buffer and index buffer)?

If not, what is the recommended approach 

Environment: Creo 11.x, ProToolkit C++, Windows x64.

Thank you.
