[GRASS-user] importing .dgn files in grass

[nishith datta]

hi all
I have been able to import a dgn file into grass using the v.in.ogr but I
have all the point, line and poly
features in the same layer. Next When i use v.what then I get a attribute
listing which I can't quite understand
Anyone who can help me out with - how to seperate the point , lines and
polys into three different layers. Also
if possible there could be different things represented as lines - roads and
rivers both are line features. So how to extract these from the .dgn file
into two different layers. I am attaching the output of v.what command for
ease of anyone who wishes to help me out.
Output of Grass v.what command :-

East: -21786.9555969
North: -23164.1739966
Map: nkd
Mapset: PERMANENT
Point

Layer: 1
Category: 9362
driver: dbf
database: /ramdisk/grass/locations/43p/PERMANENT/dbf/
table: nkd
key column: cat
cat : 9362
Type : 17
Level : 3
GraphicGro : 0
ColorIndex : 0
Weight : 1
Style : 0
EntityNum :
MSLink :
Text : Paswal

When I try to see the layers in the .dgn file using the option list
available layers in the dataset and exit from v.in.ogr
I get the output
Data source contains 1 layers:
elements

But I think the data source contains more than one layer - atleast one line,
one point and one poly for sure. What is the meaning of the above
output.....



Thanks in advance.
