Hi Kondou

The constructionline3 script is here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=1029.25

Place the .js and .htm files in the MoICommand folder.
Make a shortcut key. Mine uses the C key, and ConstructionLine as the command.

(I use CustomUI also, so my file name has an underline in front of it _ConstructLine
)
