Is it possible to use a Script within an action? - it doesn't seem to work...
I'm using the 'round any corner' script from SATO Hiroyuki..., and I'd like to apply it to only one anchor point (on multiple boxes)
An Action can call a script from the File>Scripts menu by means of the Add Menu Item Action step. But it will only work for the duration of your Illustrator work session. If you quit AI and then restart it, the Add Menu Item step will be blank. This bug has been reported for FOUR FULL VERSIONS of this sloppy program.
However, if I am correctly understanding your description of what you are trying to automate, an Action will not be able to automate the selection of a particular anchorpoint in multiple paths. You'd have to make the selections all at first. Whether the script would then apply as desired to each path depends on how the script is written.
Thanks again JET! Very helpful!
