Lisp To Draw Duct Work 1

[buffer72]

Can some one tell me where I can get a free lisp to draw double line HVAC duct work or where I can get the code and write it myself.

Thanks in advances

Sincerely

Hi Buffer72

I don't know if a lisp is what you want. Have you thought about Multi line usage?

Ps Hope you have a good Christmas.
