To add dimensions in sheet layers, we have to enter into an annotation 'layer' of the individual viewport.
Making changes involves a lot of clicking with the mouse.
I wish, we could just add the dimensions right there in the sheet without ever leaving the 'top layer'.
The dimensions would somehow automatically adjust to the scale of the viewport underneath - and would automatically change when the scale of the viewport is changed and move, when the viewport is moved.
And why not?
