Labeling Areas-Part 2

Hello,

	I'm reposting this message because I got some major problems with my
mail server and my Linux box (and I have lot of messages not delivered
for a couple of months).

	Sorry if this message is being repeated or quite out of date.

	Adalberto

	It works, Shawn!

	But, as you said, this applies only for this kind of very small job.

	So, I'll ask you in advance.

	In a couple of days I'll put a large geologic map on top of my digital 
terrain model. And this is not a matter of a half-dozen pretty good
rectangles.
My primary source is Autocad drawings and I may get a huge dxf file with
as many
as we can realise polygons with very strange forms...

	How can I edit the vector ascii file in order to convince Grass that my
former Autocad areas are real & good closed areas that I can attach a
label?

	Many thanks,
