Did some more work on the chain script.
Copied link1 to link2 and rotated 90 degrees.
Created Flow baseline. These were fairly easy as they just follow the same pattern as the previous factories.

Currently bogged down with trying to get "Array Dir" factory to work in script.
Not sure if the Array output is a list of multiple chain links or ...?
Still fuzzy on objects versus object lists, and object lists with one object, and how to concatenate
link1 and link2 with .addobject...etc...

Then will have to get the Flow factory to work in script...
