Hi Arie,
I mean, on big and challenging projects where you have to find your way to properly assemble you data, the documentation can't help.
Of course, as you said, there is a lot of informations on the helpdesk, social media groups and forum. All those informations should be packed in the documentation. I'm sure that after years working with Metashape you can use it like a charm, but I've never been so lost starting with a software. The worst thing is that many things have changed over time, they are not named the same and it makes the helpdesk, social media groups and forum incomplete or wrong.
The worst case is when you try to use the Python API, you'll find most of the solutions on the forum but once again, some function's name have changed. It wouldn't be very hard in Agisoft's side to concatenate all solutions given as examples in the python API doc, so that we won't have to search in the forum for ages. Most modern software have an online documentation structure which allow you to search efficiently trough the documentation and other discussion platforms at once. It's not the best example, but QGIS has a good documentation:
https://docs.qgis.org/3.16/en/docs/index.html You can choose the version, make efficient search and you know what? It's open source, so they could just have told users to look at the user manual, helpdesk, social media groups and forum to solve their problem but they made a clean documentation instead!
