Strange measurements in D-Cad.

I have experienced this quite a few times, but never really understood why. Before I have not seen it (I think) on drawings that I have made my self, but on drawings imported from architect dwg files and such that perhaps was not in correct scale.

But here the drawing scale is 100, but what I measure and what I measure is not the same, a factor 25 something wrong.

How I made this drawing: I had a similar drawing on A3 landscape in scale 1:200 - but I wanted to "zoom in" and have the drawing in 1:100. So I made a new drawing, with A3 portrait, scale 1:100 and copied parts of the first drawing to this new drawing.

How to fix this??

Before I try to understand completely what you say, I'll ask: What units??

First I imported the dxf into the other drawing, scaled it correctly acc. to what drawing scale it was originally. There no problems. Then I copied part of that D-Cad drawing to another drawing, with another scale.

How to fix this so the drawing scale and measurements is correct??? I don't understand why it works on the one drawing and then not work on the other I copy parts of the drawing to. The units settings in D-Cad is millimeter. When I make a new drawing, there is no possibility to choose anything about units.

Oh strange - now I just saw it. I wanted to check something else - right clicked on the measurement to see properties and saw that it is in inch. But why ot suddenly is comming in inch????

Ok I see. It seems like it was not the scale that was the problem, but the dimension settings for the drawing. That was in inch - don't know if that is default by Dietrich's, when you create a new drawing - but it could be the reason. I not often make new drawings that I need to make measurements on - I copy existing drawings, delete the content and make the new drawing...
