<DIV><FONT face=Arial size=2>Hi all,</FONT></DIV>
<DIV><FONT face=Arial size=2>I've to convert a file shape to a
.dxf</FONT></DIV>
<DIV><FONT face=Arial size=2>This shape (that contain some bathymetry data we
have to work on) is in 2D linked to a table with a column called
"elevation".</FONT></DIV>
<DIV><FONT face=Arial size=2>I've been able to create a 3D vector map in Grass
with v.extrude (but I've also been told to use v.drape) using that column for
the Z-axis.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Now I would like to export this vector map in a
.dxf</FONT></DIV>
<DIV><FONT face=Arial size=2>The conversione process reports no error but on
AutoCAD MAP 3D 2008 the elevation parameter of every contour is equal to
0...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've tried also this:</FONT></DIV>
<DIV>#!/bin/sh<BR># # # spearfish dataset<BR>r.contour input=elevation.dem
output=contours step=100 --overwrite<BR>v.db.select contours<BR>v.info contours
| grep "Map is 3D"<BR><FONT face=Arial size=2># next is just for showing
v.drape, vect map is already 3d</FONT></DIV>
<DIV>v.drape input=contours output=lines3D method=bilinear rast=elevation.dem
--overwrite<BR>v.out.dxf input=lines3D output=lines3D.dxf
--overwrite<BR>v.in.dxf input=lines3D.dxf output=linesFromDxf
--overwrite<BR>v.info linesFromDxf | grep "Map is 3D"</DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The results of this opened in <FONT
face="Times New Roman" size=3>QCAD v 2.0.5.0 Community Edition has no
objects (!) while on acad contours are showed but elevation value is equal to
0.</FONT></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any help, please?</FONT></DIV></BODY></HTML>
