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.

Hello everyone -

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.

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!
