[GRASS-user] v.to.3d for boundary?

[Robert Kuszinger]

Hi all,

I'd like to put a boundary/centroid - into 3D with v.to.3d.

Command:  *v.to.3d --overwrite input=l_00004_buf_diss at Duna
output=l_00004_buf_diss_3d height=110*

*I runs without major erro, however writes this:*
























*v.to.3d --overwrite input=l_00004_buf_diss at Duna output=l_00004_buf_diss_3d
height=110WARNING: Vector map <l_00004_buf_diss_3d> already exists and will
be overwrittenTransforming features...Copying attributes...Building

vector map <l_00004_buf_diss_3d>: B: 110.000000 T: 110.000000*

the original vector map is this:

 | Map format:
native                                                    |
 |----------------------------------------------------------------------------|
 |   Type of map: vector (level:
2)                                           |
 |
|
 |   Number of points:       0               Number of centroids:
1          |
 |   Number of lines:        0               Number of boundaries:
198        |
 |   Number of areas:        1               Number of islands:
1          |
 |
|
 |   Map is 3D:
No                                               |
 |   Number of dblinks:
0                                                |
 |
|


So, it seems that my area (boundaries) disappear during the conversion...

Topology is correct... what is the problem?
