Hi Andrew -
I think I have opened another can of unanswered questions with my original question!
Looking through the data.mp file from my system, I see "ATTR__height := -1" on almost every object type including l_flowstone, l_rockborder, l_rockedge, invisible borders and more. I don't know what that means ... perhaps an unimplemented feature? Although I cannot image what the use would be of a height parameter on a rock edge.
There is a pit in the cave I am working on, so I added "-height [6 ft]" to its definition and recompiled the map. I cannot see where that value shows up on the map.
One more thing I see is in the legend. When I use a regular "p_height" object, it draws a number on the map which is not enclosed in anything. In the legend it is called out as "floor step height", which is exactly what I want it to say. I understand why the Missouri standard calls for these to be in a box. The unadorned number get buried in the other stuff on the map.
