I'm attempting to reverse engineer a patch for my masters thesis. This patch uses a line3 object, which I unfortunately can't seem to find. I have "pd 0.43.4- extended" as well as installed "pd 0.53.0" and neither seem to have the object. If someone could point me int he direction of where to look, I would greatly appreciate it. "line3" appears in the list of objects here: https://puredata.info/docs/ListOfPdExternals/ , but I,m not sure where to download them if they aren't included in the pd-extended install itself.
