font-family:Arial'>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…</span></font></p>
