Best way to Import Models from Photogrammetry Apps like Meshroom or Colmap

I would like to import Models (ideally as tin-surfaces) from free photogrammetry tools like Meshroom or Colmap to Bricscad.

Unfortunately, the documentation on this is very sparse. Do you guys have any experience with this? I would be grateful for any pointers on where to read, look, click…

Thank you!

    Hello.

    The best importing way might depend on what file formats can be exported from Meshroom and Colmap.

    If they can export data structures as a point file, using a format like easting, northing, elevation - ENZ - then this point file can be imported into Bricscad by using the TIN command with the option Import from file.

    Another way would be to export a triangular mesh and import it as such in Bricscad.
    Then, this mesh should be exploded into 3D Faces.
    Finally, the faces will be used to create the tin surface - TIN > create from Faces.
