[GRASS-user] v.in.ogr of a 3d shape

[Sebastian Schubert]

Hi,

I want to read a 3d shape. Unfortunately, it does not finish (killed
after 2 hours!). Qgis is able to import it although I guess it is done
in 2d what grass is also capable of without the -z switch. Here is the
output with grass 6.4.1:

>  v.in.ogr --v -z dsn=St_Flaeche_3D.shp out=basel3d
Projection of input dataset and current location appear to match

Here it stops to produce output but still there is 100% CPU usage. Any idea?

Thank you
Sebastian
