    I would like RC to be able to  be able to import unordered point clouds from another photogrammetry, from SLAM LiDAR and from Drone LiDAR.

    Is there alternative to the Faro Scene method described here ? That method seems expensive and very time consuming.

    Insepes 1, this is not possible now. I will add your vote into our feature request database to increase of its priority.

    The similar way it should work in Cyclone, but it is also not free soft. For now there is no other workflow.

    Thanks, I will try the new version of Leica Cyclone Register 360 which appears to create a setup when importing unordered point clouds (page 28 of Release notes) . I will then export the point cloud and see whether it becomes ordered ? Fingers crossed.

    Please add my vote into feature request as well. We have Faro Freestyle handheld scanner, and even with process described above it is still a questionable solution: virtual scans see through points and pick the ones on the other side of the mesh, so basically making them with inverted normals. Which leads to huge problems during mesh reconstruction. The only workaround i found is to manually cut the scan in pieces and try to place virtual scans to minimize inverted point, though completely fixing this is impossible. So i have to say that solution is far from perfect or even good.

    Bazyzzy, when you have handheld scanners and not so big object, you can also try this workflow: https://support.capturingreality.com/hc/en-us/articles/4408415049618-Using-a-model-made-by-a-handheld-scanner-in-RealityCapture

    I will also add your vote into the feature request.

    Ondrej Trhan CR most of the time we are using handheld scanner to reach small and narrow areas where its impossible to place terrestrial scanner, so scans from handheld mostly are smaller parts of bigger mesh. Any workflow you can suggest given this info? Thank you

    Insepes 1, Did you use cyclone 360 successfully?

    I've not had a chance to test it yet. When I do I will post the result.

    I have tried this workflow every way that I can possibly imagine. I have exported a working e57 that can be read by Cloud Compare with working Virtual Scans that are even registered and not registered trying multiple methods. I have not found a single way to incorporate this workflow into a project that I am working on. Mainly because the roof of a large building seems to have holes in the data so we happened to have flown this with aerial lidar. I have imported that data into faro seemingly correct. It is unordered data but when I follow these instructions and go to import into RC I get roughly 4 seconds where it thinks about using the data but nothing imports.

    ecko360RC, how many virtual scans have you created? Have you followed placing like in ordinary scanning? After import into CloudCompare were you able to see the TLS/GLB positions here? Have you used E57 from Scene or from CloudComapre?

    I have been able to see the TLS/GLB positions in cloud compare from the exported .e57 which are the created virtual positions from scene.
