Messed up model

Hi,
I have a strange begavior of vertices in my model. It happens when I get to import stuff via dxf importer. I scaled model 100 times and now vertices seem to snap to “some” grid when I turn model around.
Here is an image ilustrating whats happening.


Thanx for help!

Could you scale it before the export? It might be floating point math errors on small values during the import.

Could we see some example, please? You don’t even say if you rotate in Edit or Object mode…If it is Edit mode there is nothing selected in the image; is it before or after rotation?
