image problems and labeling problems

Hello,

  I have just digitized a map from autocad. I have closed up all the
polygons and I am now trying to label the polygons. This however is not working
When I use v.digit to label the areas I am running into the problem that the
labeling routine will no recognize the lines on the map.

  I first define my category and then pick and accept a point but when
I go to pick a boundary line I always get the message no line found.

  What am I doing wrong and is there a problem with my original
digitizing.

  Second, I need to convert this same map to UTM coordinates.

  How would I go about doing this.

thanks,

tom
