I have noticed this behaviour too. I think the basic reason is that parallel projection exports are correctly scaled across the picture plane, so that would make the objects parallel to the model axis in an ISO export foreshortened. Switching to an ISO view from a plan view only changes the viewpoint and has no effect on scaling. If you draw a cube or a square and export an ISO view, the top horizontal diagonal will be to scale. Of course this is not according to standard.

have you checked if in the pop up import dwg window, in the button options, your unit is the same of your cad file?

It's a different thing of the units in the SU file itself.

you're actually leting the SU know the units of your cad file...
