Degenerate DXF

[N R A]

Firstly thanks to everyone who replied to my first message.

Further to my comment about GRASS importing DXF and reporting 'degenerate 
lines', I'm wondering in GRASS handles the POLYLINE format of DXF - 
perhaps I should 'explode' ?? the Autocad entities - I believe this 
reduces the 'complexity' of the lines, etc. 

I must admit to being a bit puzzled by the problem - I have a test 
boundary, consisting of basically two straight edges (fault lines) plus 
two arcs of a circle. Importing in Corel gives four straight lines - I 
assume Corel doesn't handle POLYLINE. Importing into Word for Windows - 
it thinks the DXF is 'damaged'. Finally GRASS - I get the 'degenerate 
line' for one of the lines ??

Can anyone comment on this please
