[GRASS-user] r3.out.vtk for paraview

[Francois Chartier]

Problem solved.  the solution is to define the folder location where the
file should be saved.... typically, we just have to define the file name

(Wed Nov 21 21:55:24 2018)

r3.out.vtk -s input=nov817tension100 at Toronto output=C:\Users\Francois
Chartier\Documents\GeoModel\vtktrial top=GTA_DEM_Raster at PERMANENT
bottom=Rock at Toronto
The 2D and 3D region settings are different. Using the 2D window settings
to adjust the 2D part of the 3D region.
