> I've been having a play with the ESRI format model and can display shots and stations but not the walls. Am I doing something wrong?

Back from caving…

I do not have access to 3d GIS, and limited access to 2D GIS. 

If you are referring to ‘export model –format esri’ then I cannot comment.

If you are referring to ‘export map –format esri’ then about 12 months ago (I have not used it since then), the points, lines, areas and cave outline are all exported separately.  Unless you are prepared to define symbolism for each ‘attribute type’ of point, line and area, then I would suggest they are of limited use.  The outline (passage walls) is however quite useful, and has attributes that allow one to fill, colour and or label by altitude, scrap name, and perhaps others; I forget.
