Mac book Pro, 2.53 GHz intel core i5,
8 gb ram 1067 ddr3, graphic nvidia geforce GT 330M 256 MB
blender version 2.73,
it has error in dxf and obj format while importing files.
dxf has some version problem and obj has problem with script.
i am a begineer to blender and i use it for rendering of architectural models from sketchup.
can't we have sketchup format as import so we can retain group and material properties.
regards
hasan
