Sheet Scale & Dimenions scale (2 different dimensions scale on one sheet?) 1

Hello, I am pretty new to Drafsight, and I have a drawing started in a 1:10 scale.
Now I wanted to copy a small detail out of the drawing and scale it 1:1 beside the 1:10 drawing on the same sheet.
My Problem now is that the dimensions scaled accordingly, I tried adjusting the linear dimensions scale in the preferences menu, but that always applies to the whole sheet and not only to the selected drawing.
anybody know what to do?

Thanks
