Hi guys!
I got a SHP 3d with countour line at 25m and using this,i had to create a dem;
I imported the shp using v.in.ogr and enabling the flag for 3d shp and this is 
the v.info output:

[..]      
Map Scale:  1:1                                                           
Map format: native                                                        
 
Type of Map:  Vector (level: 2)                                          
Number of points:       	0               Number of areas:      0          
Number of lines:        		2918           Number of islands:    0         
Number of boundaries:   	0            Number of faces:      0          
Number of centroids:    	0             Number of kernels:    0          
Map is 3D:              		1                                                
Number of dblinks:      	1      
[..]

The associated table got element like those one:

id | cat | id | igds_layer | eq_lvls | altitude 
1	1    0		....		5	  100m (the value of the cl)

Doing a query on the vector map i noticed this anywhere:

map: 'cdl25m'
mapset: 'PERMANENT'
feature type: Line
length: 4008.907401
Line height: 0.000000   <== Is this ok with 3d file?

Then I started v.surf.rst with this vector (after setting the res to 20):

v.surf.rst input=cdl25m layer=0 dmin=0.5 elev=dem20 tension=90

But the raster output has got all cell with 0 altitude...what i am missing?

Thx
Luca
