Macro for floor heights

[Sageland]

I spent the afternoon working on a macro for the height of the ceiling on a 2 story. I am not sure that I understand macros very well, but I think that they could save time.
I started with a macro that Gerry had posted quite a while ago. It worked great for a single story, but when I used it on a 2 story, I got a height of 18'3".
Here is what I came up with.

roomht = (ceiling_elevation - floor_elevation)
roomht = roomht.round.divmod(12)
"Clg Ht. " "#{roomht[0]}'-#{roomht[1].round}''"

Scott, I hope that I will learn more in a few weeks in the workshop.
