What do you mean by "ants to finalize the Selection with another point to create a 2D polygon" exactly?
Is it because the trace polyline is not closed maybe?

Re: Normal Calculation not working as expected.
If there's one (or several), you would see them in the cloud properties. And if there is, then you can probably remove all the other options.

Re: Command line classification
Yes, that's because with the command line you need to explicitly specify how to manage large coordinates.
You should add just after

Re: Normal Calculation not working as expected.
Not sure to understand... Does your scan have an associated scan grid (because in this case you don't need to use any of the other options. If not, then you need a radius as large as possible so that enough points are captured in all areas of the cloud (normally the 'Auto' button works quite well to...

Re: Cloud Point showing up as a straight line
And what the bounding-box looks like once you've loaded the cloud?

Re: 3d texture from rgb pointcloud
Sadly CloudCompare is not able to create (mesh) textures.

Re: Interpretation of C2M signed distances when the distance between points is great
Can you send me these meshes so that I can double check things on my side? (the new version of CC is more robust, so the C2M distances should not have the same issue as before with 'flipped' distances, but I don't see why the reported distances would be much larger than what you expect...). Essentia...

Re: Cloud Point showing up as a straight line
Also, a classical issue is if the points are expressed in a 'geographical' coordinate system with X and Y being angles, and Z being in meters (i.e. with a totally different scale). CC expects all 3 dimensions to be the same. Thank you. How can I check or edit this upon import? You'll see that right...

Re: Register 2 extra clouds
Well, targets are always a very robust solution (but CC only accepts spherical ones). But otherwise, I would recommend using 'point pair based alignment' at least to roughly register the new scans to the group of already georeferenced ones, and then if necessary run ICP to refine the result (with th...

Re: Poisson Surface Reconstruction Vs Rasterizing
Well, the Rasterize tool is to create rasters (geotiff), which is quite different from a TIN/DTM represented as a triangular mesh (what you would get with the PoissonRecon or more simply with the Delaunay 2.5D meshing tool). Also, most of the mesh formats don't handle large coordinates (contrarily t...
