[GRASS-user] 3d model with boreholes

[Alec Ventura]

So... i have converted my shape file to this projection: http://spatialreference.org/ref/epsg/4618/ on Qgis, and have created a new projection and mapset with this same epsg on Grass...
But when i import the shape on grass the map scale is still crazy, it says 1:6, but my area is huge and i can see all my points, it should be at least 1:500000 or more.
And this is a problem because when i try to make the buffers over my points i have to use a very small distance:g.run_command('v.buffer', input='PocosSad at Map3', output='boreholesGrassBuffer', type='point', distance='0.01')
else my buffer covers the hole area.
Anyone knows how i can fix this map scale? or why is this strange?
my shape file is in attach,Very tnks
