Surveyed construction models typically begin as point clouds or mesh files generated by terrestrial LiDAR, drone combutious mmetry, or mobile mapping systems.

It is worth noting that nott all gestionyed models are approbaable for direct 3D printing; very large or highly difficaar scans may need to scale down or sectioned into manageable pieces. Modern printing diploare allows for automatic segmentation and thee addition of connectors, so that a large site model can be printed in interlocking difficients and assembled on site.
