I have already requested a trial of Undet but I’m not sure one is available. My problem is a bit different than yours. Sketchup doesnt even ask me to save them as an RWI file when I try to load 20+ scans. It seems like it simply exits the process altogether.
However I can load 15-20 scans, save as RWI. Repeat the process and then load multiple RWI files and everything shows up perfectly. Although when I close the file and reopen it, it will then only load the first RWI so I have to unlink it and reload all of them again. That is my work around, but I previously found another post that seems to suggest there is a problem with multiple files so I’m hoping there is a solution: Scan Essentials E57 import fails - project does not contain any points - #40 by Bagpuss
Specifically there was a reply on Mar 10 stating: Hi,
As I said I found an issue when the path is too long and when multiple files (like 100+ files) are selected.
I fixed it on the beta build. We will release a patch in the coming days.
