[Therion] Height numbers in square boxes

I think the height attribute is only used for the AUT symbol set, for line pit, and line wall:pit.  Look in uAUT.mp
If the pit height is greater than 10m, then the open triangles are filled in.
If the pit height is less than or equal to 10m or undefined, then the triangles are open.

Looks like if you want to label the pit, you should use point height and place it near to the line pit (or line floor-step or chimney whatever).
ie completely independent input required by the user.  A bit like how point sink and point water-flow are intended to be used tother.

Yes the Missouri set would be even better.

The therion book indicates that height can be added to pit or wall:pit
p29
"height <value> ▷ height of pit or wall:pit; available in METAPOST as a numeric variable ATTR__height."

I guess that would also make sense for a floor-step, however if you try it you get the error -height not valid with type floor-step When you use an altitude on a wall it adds a label but does not seem to with pits maybe the same should happen with steps and pits, currently I have no idea what happens to the height attribute on a pit. Looking at data.mp the l_floorstep does have a ATTR__height and it is set to -1!

Yes I'm having similar problems to you defining a box, my skills are generally limited to copying existing definitions and adjusting them slightly. My guess is that it is not a metapost, it is tex as it is a label, in tex you can put a box round text  with

\fbox{4}

but how or if you can use that in therion I do not know.

It is a problem that is interesting me, as I think it is something that I might want to use.
