Hi Ch.D.
You have two cases :
1- graphical patches attached in the forum. In fact they are lisp code. So in order to import it :
a- Save-as the attachement by appending “.omp” to its name, like so mypatch.omp
b- THen you can import it as a patch in om. Without this extension, om will not recognize it as a ptch
2- Lisp code (not patches), are not importable. But you can open them using your listener. Usually they should have as a first line :
(in-package :om)
if you need to use the contents as a graphical function or method.
Hope this helps
Best
