Hi François,
Thanks for sharing the solution you found. From your first mail it was
clear to me what these voxels above the DEM contained. NULL values ?
It would be great if you could summarize all your experience working on
3D data in GRASS GIS in the wiki, at least by amending
https://grasswiki.osgeo.org/wiki/Help_with_3D with your additions or
corrections ? This would be very helpful many others.

See attached screenshot, I was able to remove voxels above the DEM and
below bedrock surface using r3.out.vtk and selecting export as
*pointdata (p)* not voxels. If exported as a Voxel from r3.out.vtk, the
voxel file did not open properly in Paraview could be due to size of
file. I changed option to export as points and it is working.
grid resolution is 5 x 5 x 1 m over 4km x 4 km x 65 m thickness approx.
(actual thickness varies between DEM and top of rock).

Hi,
I would like to remove voxels located at a higher elevation
than DEM.
I have been trying r3.mapcalc without sucess.
Does the XY resolutions of both raster have to the same?
any ideas how to do this?
Thanks
Francois
