[GRASS-user] Creating 3D Vector file (v.in.ascii) for eventual use in NVIZ

[Dylan Beaudette]

Nice presentations Jachym!

Unfortunately v.drape may need a couple bug fixes (!) , as I wrote it sometime 
ago, and have not gone back in and inserted checks for features within 
region / within extent of elevation surface , etc. 

Cheers,

Dylan
