Is it possible to modify the triangulation of a surface in TBC 5.7 or TBC 2024?

    Hi Trimble Community,
     
    I hope this message find you well, in the last weeks I have been working and learning how to generate terrain surfaces with TBC in versions 5.7 and current versions like TBC 2024.
     
    My question is oriented to the triangulation of the surfaces, is it possible to change the size of the triangles?
     
    The current workflow is as follows:
     
    I process the point cloud with the DJI Terra solution, this makes me a more accurate terrain classification than the classification offered by TBC, once the point cloud is generated I import the .las file to TBC and that's where the magic starts to create a surface from the terrain already classified, the detail is that when generating the surface the triangulation is very large and does not respect some points of the terrain.
     
    I have been trying with other tools to process the point cloud and the triangulation improves significantly then, I do not know if from TBC I can modify the size of the triangles or that would be properly of the software that processes the point cloud?
     
    I attach an example capture for your reference in case my message is not very clear.
    The size of the triangles change significantly using 3DSurvey
    I appreciate any comments you can give me.
    Best regards,

    You can try upping the surface points in the options

    I too have encountered this. I am surprised that it is not one of the options when creating the surface.
