Hello all and thanks in advance for your patience and assistance

I am very new to this BobCAD program and thus far I am adapting fairly well. The question I have is when I merge a DXF file into v17 no matter the original dimensions of the drawing it comes in at like 300+ scale and then I must then scale it down to scale 1 in order to have an accurate cut of course. The problem is I am only seeing the ability to scale both length and width simultaneously? So how do I or am I able to scale either just the length or width of the original merged drawing independently?
