From the sound of it. You draw everything at 1:1 as everyone recomends and then for plotting details you make a copy of that area and move it somewhere in model-space and scale it, is that correct? MAN what a waste of time. The idea is draw 1:1 in model space. then in paper-space have layouts for different sizes of paper, then use viewports in the layout and only ever use scale in these viewports so on a single sheet of paper you could have a ground plan at 1:100 then a room plan next to that at 1:10 and finally a detail of a door handel at 1:2 all on the same sheet of paper and ALL looking at that same single model you drew. All of that nicely bordered with your title block labelled up correctly, and when it comes to make any changes then you edit your door handel and it shows up in the other two viewports as well.
Then on the next sheet you have the second room and a different window. Now take the whole project and all your door handels use a block, then you make a change to the block, and every single door detail in each and every drawing is also altered.
