[Therion] "Passage height" question

[Bill Gee]

Hi, Martin - You have an excellent idea here!  I did not think of using 
alternate units.  

Unfortunately - it does not work.  When I put "-value [6 in]" on a point and 
compile the map, it displays as zero.

I suppose I could convert the entire map to inches.  That would be a pain 
since there are also 40 foot ceilings in the cave.  

Could I put in something like "units dimensions feet, inches" in the 
centreline section?

I would rather use metric, as someone suggested.  I don't have that option on 
this map - all the data is in feet and tenths of a foot.  Maybe the next cave 
I do will be in metric.

Thanks - Bill Gee
