'Nother little routine

All of my routines are geometrical in nature and are basically regular ACAD
commands with a purpose. Here's a cone-developing thing that was done last
week. Don't know why I never did this before.
A little info: the routine lets you pick 2 lines which would be the
generators of a cone. Please make sure that both lines are the same length
or you may get funky results. Oh yeah, it's in french, too.
Copy and share.

Using R14. Returns this message:

Try switching the hyphen with a period: "_.array"

Indeed so. Thank you both for the routine.
