I’ve just noticed something ‘new’ on my iPad (Pro): When I import parts (mostly from GrabCad), the grid suddenly behaves strangely. When zooming in, the grid suddenly disappears. I have also noticed that the value in the grid size (top right in my case) does not go below 10mm anymore. If I delete the part, the grid behaves normally again and the grid size goes down to very small numbers.
I have already tried everything, restarting, saving the project, exporting in Shapr format - it stays the same.
The effect does not occur with every part - but with some of them and it is reproducible.
