When selecting a new drawing I am no longer aksed for which size I would use (A3, A4 etc etc.)
What have I turned off ?
You have saved the template with a sheetformat in it. Create new drawing, delete sheetformat from design tree, resave as template.
Could be either of these two options. So select them and check.
Check this setting please
Both are checked, but still no dialog.
Meanwhile, I deleted the template from the folder and got SolidWorks to create a new one.
