How to incorporate existing .sb as a (sub) graph?

[llama...@gmail.com]

Now that antimony has hierarchical graphs, how would I take a .sb and include it in a new project?

Nesting files within one another isn’t yet supported, so you would have to copy/paste from one file into the other.

Since you’re interested in this, a quick question: what makes more sense to you, between

a)  Including other graphs by reference, e.g. if you edit the original file then the embedded graph changes

b)  Subgraphs included by value, so they’re distinct from the original file

Well, that was one of my questions too.

It looks to me that you have to have "by value": copying a subgraph or inserting an external .sb as a "subgraph". This is "grouping", mostly to control visual complexity.

But, I also think "by reference" is valuable for a "parts library" type behavior. E.g. The 10 instances of a screw should just reuse the screw subgraph. Probably, external files are cached and immutable (maybe with an "update" action). Maybe call this a "parts" behavior.

You convert a subgraph to a "part" by "make part" (or use an external file as a "part"). You could convert a "part" to a "subgraph" by "copy as subgraph".

Internal parts (not from an external file) must be editable (to refine/fix), but that is a special situation, because you are affecting all of the appearances. It should be obvious that you are affecting multiple "appearances."

How do PCB programs do it? They have parts libraries. What happens when the parts library is updated? I suspect your existing PCB doesn't suddenly change.
