- Date: Tue, 27 Oct 2009 18:34:05 -0600
There are not currently any tools that save and restore auxiliary data
like the splines. As such there isn't currently a model for how that
interaction should work. It's also non-trivial to set this up so that
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.
