[GRASS-dev] v.in.dxf: support for 3DFACE?

[Hamish]

Hi,

all excited to try out v.in.dxf :) but 3DFACE isn't implemented yet :(

I can convert the DXF to a polyline version, and import with the new -f
flag, but I need to run v.build before I can display it. After that I
can do g.region v=, display with d.vect, & display in NVIZ (3D vector).

Looking in v.info the x,y,z ranges are all 0,0.
Note the final x,y ranges are both negative. (?)

after import:
 |            N: 0.000         S: 0.000                      |
 |            E: 0.000         W: 0.000                      |
 |            B: 0.000         T: 0.000                      |
after v.build:
 |            N: -4816.565     S: -5951.313                  |
 |            E: -1943.884     W: -3092.723                  |
 |            B: -11.644        T: 54.011                    |

??


Also it exits with "No DXF layers found!" for the 3DFACE import.
This had me really puzzled as the layer does exist, it is just all
of unknown feature types. Could the error message be improved?
"... with data!"
"Layers found with no features"
"No features in layer"
???


Any plans for 3DFACE support? The wireframe is good stuff, but just a
skeleton. :)
