Yes the Missouri set would be even better.
A common convention around Missouri cave mapping is to indicate the height change of a floor step by enclosing the value in a square box. This is not the same as ceiling height which is enclosed in a circle or oval
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. Andrew On 20/09/18 13:09, Martin Sluka via Therion wrote:

Hi Martin -
Now that is an interesting idea! Most of the symbols used in Missouri are UIS, so that would serve as the starting point.
Is there any documentation on how to create an entire symbol set?
And my original question is still there ... How can I create a symbol that puts a number inside a square box?

The correct way could be to define “Missoury symbol set” as one of defaults for Therion.
It should be more simple than user symbol, because it will work with contents menus.

Hi Andrew -
I have defined several of my own symbols such as a pendant and popcorn with hollow circles. I could easily define a custom point that would display a square box.
But then how to get the value displayed inside the box? And how to make the box scale according to the number of digits it contains? And will Therion do unit conversions like it does for the passage-height object? That's why I was looking for the existing code. If I can find it, then it is probably pretty easy to modify.
Yes that is probably possible, however, using a defined symbol for something else is probably not the right answer. Therion allows you to define your own points.
From the wiki
point u:xxxx where xxxx is the name of a user defined symbol that you have defined or referenced in a layout.
The actual definition seems to be beyond me at the moment, let me sleep on it, but hopefully a more skillful person will have the answer.

I have been using the object "point height" for this. It works except there is nothing around the value. It just hangs out in space, so to speak.
I used the "-d" option to dump all the MetaPost and TeX code. I find no references in any of the files to objects of type height or passage-height, which implies that these two objects are not generated by MetaPost.
Is it possible to redefine the "point height" symbol so it draws a square box around the value?
Thanks! -- Bill Gee
