Hi,
by default a drawing should only have a scaling for printing, that means in the layout there are viewports and each viewport can have it's scale to show the object scaled on a paper.
But in modelspace the model should be drawn 1:1 in that units you are used to work. To verify that you can run command _DIST and measure a distance of an exiting entity that you know how long it should be. Then you know how long this object is in modelspace and if it's drawn 1:1 or not.
