DXF import craziness

I have a question concerning dxf import,
whenever i imoprt dxf file it seems to change the dimensions of objects : for example a line 2 m long would be like 1.975 or something, plus whenever the axis would not be perpendicular to monitor it import all wacked (as u can see here)
can anyone shed some light on this for me? Do i miss something or is this normal behavior?
Is there a better (more fluent) way to import CAD files into blender?
Thanxx!

ok, answer myself: it was due to far far away origin of the coordinate system :slight_smile:
