Is there a procedure for scaling a detail (including its dimensions) which results in correct scaling of dimensions? I can scale the whole detail and all its annotations and dimensions, but the units in the dimensions don’t work out correctly and need to be redone.
I had a look and as far as I can work out there isn’t any option for exactly what you want.
However there may be a quick work around, that should save you time.
In document properties you can scale up all text in one move, rather than editing each individual measurement.
