cad3d converting problems

[Roger Schuster]

Hello all,

I played around a little bit with the brand new Survex 1.0.8 release on a 
Windows XP machine. I tested the cad3d tool with some of my own data and 
with the Austrian samples from www.survex.com.

Because I used Compass (a surveying software from the U.S.)  in the last 
years I first was interested in the capabilities of the -P option which 
converts *.3d files to *.plt (the native file format of the Compass Cave 
Viewer). A smaller cave (~1000 m, ~60 stations) from my own data was 
converted without problems. The *.plt file looks in Cave Viewer the same as 
the *.3d file in Aven. The all.3d from the Survex sample data was a bigger 
problem. The elevation looks in Compass nearly the same as in Aven but the 
plan view in Compass is very distorted. You can see the survey crossed by 
vertical lines - looks like a cave map with a bar code printed on it. :-)

The DXF export of large caves from the Austrian data seems to be 
problematic, too. Corel Draw 9 crashed if I imported all.dxf.

Happy caving

Roger
