The trial version is not limited. After the trial ends, you will not be able anymore to load point clouds into SketchUp, all created geometry models will be saved in a SketchUp file for further use.
There are no special requirements, current workstations or gaming laptops can handle massive point clouds:
The Undet software license requires your digital system codes (SITE & MID) to be activated. These codes can be find via Undet license manager can be opened in Extensions -> Undet menu by clicking “About”

License is stiched to computer hardware, not to the user account.
Yes, there are no restrictions.
MAC is not supported.
We cannot guarantee that it will work, but we know that some users use Boot Camp to run UNDET on MAC. Please try before purchasing a license.
Virtual Machines are not supported.
You can import any point cloud file from 3D laser scanner, UAV or photogrammetry software. Supported point cloud formats: *.E57, *.FLS, *.RCP/RCS, *.PTX, *.ZFS,*.LAS, *.LAZ, *.PTS, *.PLY, *.DP, *.FPR, *.LSPROJ, *.FWS, *.CL3, *.CLR, *.RSP, ASCII / NEZ (X,Y,Z/i/RGB) and custom ASCII / TXT file format imports.
Only one employee can open the Undet project from the local server. To avoid performance drop when working from the server, Link speed (Receive/Transmit) should be 10/10 (Gbps). Without this speed, the point cloud project should be copied to the local SSD disk drive.
