I just opened a sketch I used a few weeks ago to fit furnishings into the living room. Today when I check a line length with the horizontal dimension tool I find that the length is twice what I intended and I think I used last time.
Is there some simple tool I may have invoked that kept my scale at 1:100 but somehow doubled all of the dimensions?
If so, I gather it should be possible to reverse the process and halve them again.
I think I may have found my answer. Am I correct? I believe the command is Edit>Transform>Scale. It seems to change the scale of the selected objects without changing the scale set under Tools>Drawing Options>Scale.
I must have inadvertently invoked the former command at some point.
