it's a general purpose and easy to use mechanism.

If you are just needing the control points for your own purposes then
your best bet would be to make a 'export' button on the tool that calls
a function which just writes curves.txt or similar, and then use that
externally.

Hi Michael,

Gosh, you are right that it's non-trivial, it's taken hours of work.
But it can be done! I just got your email as I got it to work! :) You are right, it would have been a lot easier adding a button to the tool ;)

So this is how it works: I have added an item "Export Control Points" to menu "File". I have basically copied what "Export Statistics" does, and then made some changes.

So what the new "Export Control Points" does is to get the "seeds_" vector from SplineTool, and write the coordinates to a CSV file.

It can easily be extended to other tools by writing for them a "get_seeds()" function.
