I use the Pro version.
I cannot open any version of dwg/dxf created by my copy of Autocad LT 2012 with SU 8 on Windows, nor can I open them on SU 7 on Mac (PPC). I can import a dwg / dxf created by Autocad into my Mac 2d application (PowerCadd), save back to dwg or dxf, then open easily on either versions of SU (SU 7 on the Mac, SU 8 on the PC).
It sounds like I need to tweak something in Autocad 'save as' dialog, but I am not sure. Any ideas?
thx for the help!
