I think you should remove the character "#" for all lines with data. You must go from lines like these: # x y z To lineas like these: x y z You can do this, using the linux command "sed". You must execute something like these: $ sed 's/^#\ *//g' datos_orig.xyz > datos.xyz > > Using v.in.ascii, I checked Create 3D file > > selected the input file, in this case 0834_10.DTM and typed the out put file > osi0834.

Can anyone give me any advice? If I understood, you must delete the "#". See my previous comment in this message.
