Help reduce excessive nodes

[mohdnaka]

Dear Grass Users,

I am trying to label contour lines that I have converted from DXF files. It 
seems that the contour line contain lots of nodes within one contour line.
How can I reduce these nodes, so that labelling the contour lines will be 
easier. I have used v.trim, with the option factor 0, to reduce this excess
nodes. It seems to reduce the number of nodes, but it also reduce the contour
lines. How can I overcome this problem?

Thanks in advance for any help.

Cheers,
Kamarul
