How to generate a TIN (triangulated irregular network) file

Topcon is a survey equipment manufacturer that has software which automatically controls construction equipment. The operator inputs a surface into the machine which controls its operation. The input file is a TIN file which is frequently used in terrain mapping and consists of a series of triangles matching the actual surface. I am trying to generate a TIN file using Rhino 6. I would like to know if there are any plug-ins or other software which uses Rhino that can generate this type of surface.
