dxf files, AutoCAD 2004, and Blender 2.35

Use to have a pretty easy time bringing ACAD .dxf files into Blender for additional modelling / rendering. Just recently – after installing 2.35 – am having trouble with same. My imported files tend to have correct arcs but lines tend to not show up at all or are in the wrong places.

Has anyone else noticed same? Any new ideas?

Thanks in advance,

John K.
