The version you provided me by PM seems to be working without problem - thanks!

Hi.

I too am having the same problem using Stair Maker as posted above.

The error I am getting in Ruby Console:
"
Error: #<ArgumentError: Cannot convert "12.3031496062992" to Length>

"

I'm working in EU comma separated units (e.g. 14,54m).

Is there any known solution to that problem?
