correcting elevations on digit. contours

[Radoslav Bonk]

Dear GRASS user, 

I would like to ask for an help or good idea on such a problem:
	I am working on a project of computing DEM from digitized
contours. It is together about 120 maps with contours and elevations /DXF
format; 1:50 000/. 
	And the problem is that some of contours have bad elevations. I would like
to check all maps to find a mistakes and afterthat cover a raster
DEM with contours to correct elevations in ArcView database. 
	And afterthis operation compute whole model. Even there is a
smaller DEM /1 map sheet/ in GRASS, not every mistakes were easy to see. 
	
	I would very appreciate any idea how to visualise
problem regions on map sheet in GRASS GIS?
	
Thank you at all
				
Rado
