I have upgraded AC 10 (since yesterday). Except that I have done nothing.
The grid made by grid tool is in section & elevation no more visible generally for every new project.
It is very funny.
Add-on is right there.
I know how I use this tool.
Yesterday I worked on it with satisfaction.
But now I can't produce grid on section (no more linked from floor plan)
I tried in empty project, but same result.
