no, I don't have much problems with xp. It only sounded a little bit 
like that I need Macosx for the 3dim part (3dmf). Probably a more 
detailed information about the 3D part would be nice in the manual or in 
the wiki (howto, 3D-viewer, ....)

Probably not. I've included the survace in a very simple way: I created 
a list of fixpoints

survey dem
 centreline
 flags surface
fix x0y0 723150 2291580 876.52
fix x1y0 723240 2291580 900.91
fix x2y0 723330 2291580 921.25
...

data nosurvey from to
x0y0 x1y0
x1y0 x2y0
x2y0 x3y0
x3y0 x4y0
x4y0 x5y0
...

So this is possible not the best way to do it, but it seems that I 
missed the correct way of doing it in the manual. So I will read the 
manual again.

i included once a graphic in the pdf but I did not check the xtherion 3D 
viewer and the vrml that time (also no DEM was included at that time). 
The last view times I exported the cave as dxf, converted it into a ESRI 
shapefile and did the overlay externally.

No still in the survey book. :-(((  (And it's not my survey book)
