I too use C3D to start my surface grading but then I have to extract objects from the surface such as the 3D Faces (TIN) and the contours (2D polylines). I have not yet found anyone that puts on any sort of model building seminars or something akin - this you’ll have to learn by experience. Everything is typically in a proprietary file format too.
I have built Topcon models over the years for select clients & the only way to learn is the hard way.

File 3 is larger because it contains Point Cloud and Ortho Photo Data. Zip File 1 and Zip File 2 are the most important files. The three zip files below are required for the class. How to control densification along lines for accurate surface models.How linestrings are used in surface models.The role(s) of boundaries in a surface model.The role of breaklines in a surface model.Surface Model components - points, point clouds, lines, breaklines, boundaries.
The class will cover the basics of Surface Modeling in Trimble Business Center including
The class objectives are to teach attendees everything that they need to know and understand about TBC surface models, and how to make surfaces the most efficient for field uses.
