I have a series of vector contour maps imported from CAD files. The CAD lines were digitized in 3d so the lines were set at the proper height, and I imported them with v.in.dxf. The z values now come in as Line_height values:
east, north: 586205.150707, 4261840.15315
map28@PERMANENT:
Type: Line
Id: 120
Length: 1005.435416
Line_height: 160.0
Layer: 1
Category: 120
Driver: sqlite
Database: /Users/nick/Documents/Grass/sardis/PERMANENT/dbf/sardisutm.rsd
Table: map28_con10
Key_column: cat
Attributes:
cat: 120
layer: CON10
entity: LWPOLYLINE
handle: 3E1
I’m sure there’s an easy way to get those Line_Height values into proper z coordinates, but I cannot figure out how to do it. Any help would be greatly appreciated!
Many thanks,
Nick Cahill

Why do you think the vector doesn't have proper z coordinates? Line_height
160 means that the vector feature actually has z coordinates, otherwise it
wouldn't show Line_height item at all. If you want to display it in 3D
mode, there is an option to switch between draping on surface and
displaying it as truly 3D

Aaaah! I hadn’t seen that option in the new Grass 7. Apologies!
Best wishes,

If you see any need to improve the documentation, please suggest!
