when i open existing project,  
another ‘project files folder’ created(only with log file inside)  
point clouds and cameras didn’t available.  
renaming and isolate in new folder not helped.

Hi roy,  
I am not sure I understand the problem. Are you missing some of the expected outputs?

Hi

what i meant to say is…  
when i use the desktop app to ‘calculate a photogrammetric solution’ , so usually - i get the location of the ‘cameras’/photos while taking a picture . afterwards i create a point cloud. so far - so good.

sometimes… not always… when i open an exiting project, which was already calculated + point cloud created (you can see in the picture that 30 polylines already drawn) - i get this gray ‘Cameras’\Point cloud and they are not available…  
also another folder created, which is empty from Part1 +Part 2 data folders…

it is like the file project itself has a corruption ,suddenly.  
the only way to fix it is doing phase 1 + phase 2 all over again.

thank you for your response.  
Roy

Hi roy,  
Yes, it appears something became corrupted. I cannot comment on why this would have happened. Unfortunately, the only likely solution will be to reprocess the dataset.
