[GRASS-user] 3D DXF output: howto?

I just loaded a few dozen points with coordinates around 600000
into blender and it worked.
I was able to load the points, select them and zoom into them.
However, the -1000 to +1000 range is still present in some menu widgets
and the navigation outside of it seems difficult.
I also experimented with importing 43.000+ points and after ca. 10
minutes of waiting for the result, I killed the program.

Anyway, my coordinates are local coordinates with a very small range, so 
I will  not hit that limit.

Best,

Benjamin
