All,
I’ve been having problems importing 3 .dxf files (created in AutoCad Map (R) Release 2.0 as AutoCad R12/LT2 DXF files) into GRASS 4.2, using the v.in.dxf command. I am getting either a:
Ø bus error
or
Ø segmentation fault
error message. This results in only very small fragments of .dxf file contents being imported, without details of the files ‘drawing space’ (i.e. after running v.support, the opening screen in v.digit shows no values for the west/south/east/north edges of the map area). The file sizes of the .dxf files ranges from 1.2mb to 6.7mb. this problem persists no matter whether the .dxf files are AutoCad R12, R13 or R14. the .dxf files contain polyline entities. Initially I tried to export the cad file as a single .dxf, creating a series of vector files in GRASS based on the drawing layers. After the initial problems I broke the drawing up into a series of sub-drawings based on the individual layers. the oddity is that two of these new .dxf files have imported quite happily while the other 3 are causing the problems outlined above. Perplexing…
if anyone has any suggestions, has encountered these error messages before etc – I’d be very grateful to hear from you. Thanks,
Rob

Hi,
maybe persists for R12, R13 or R14, but I think that v.in.dxf
does not support higher version than 9 or 10.
You can use
http://sourceforge.net/project/showfiles.php?group_id=30996
to convert dwg<->dxf from any version to any other.
