Although some packages vary slightly from one-another, nearly all of them have the same PCB footprint and schematic symbol.
How do you guys actually make the footprint, for say, an LM317 TO-220 when it is not (at least by default) in the library?
I assume from scratch as I cannot see a "copy from another item" feature at least on hand, however that opens to major problems if one was done wrong.
I have heard of a default template library of most package types, that'd be amazing to use, however have not found it (or on search engines at first look) nor would I understand how to copy just (i.e. a TO-220 generic) template out and edit it in to my own library.
Any advice on what to do?
I may need to get a lot more proficient at this, as many parts I come across simply do not have libraries. I thought Element 14? (who bought cadsoft I believe) would have made a huge library with every one of their parts - that'd be amazing, again, no luck in search engine and am not even sure it is better than just DIY symbols.
