Convert, rescale and lighten 3D scanner meshes, one file or a whole folder
Convert 3D scanner output (STL, PLY, OBJ) to STL, OBJ, PLY, 3MF, glTF or FBX in batch. Set the units and up axis, and cut the triangle count with --decimate on the command line. The scan stays a mesh: it is not rebuilt into a STEP solid, and holes are not filled.
Download Free Trial3D scanners output large mesh files in whatever format the scanner software writes. The next tool usually wants a different format, unit or orientation, and far fewer triangles.
3D CAD Converter converts scan meshes between formats, applies unit and up-axis changes, and reduces dense scans from the command line. Holes and scan noise are left as they are: clean those up in your scanner software or a mesh editor first.
cadconvert convert scan.ply -f stl --decimate 0.25 keeps about a quarter of the triangles, for one file or a folder. Command line only.
Reads PLY, STL and OBJ scan meshes and writes STL, OBJ, PLY, 3MF, glTF/GLB or FBX. A PLY point cloud without faces cannot become a mesh.
Convert entire scan libraries. Drag folders for bulk conversion.
