I'm inserting a sketch that does lots of computations to determine the final output shape (an airfoil). Ultimately, it's a spline that wraps around lots of points.
I want users to be able to change things (e.g. the length of the chord line) - but in so doing, my math needs to run and re-compute the complex new shape that needs to replace the old one...
I've hooked the events needed etc and my math runs OK, so now I'm wondering what's the best approach to make the needed changes? I can't just "delete the shape and insert a new one" (I assume, I've not actually tried yet) because I expect that will break their design (e.g. if they've extruded or lofted from the original spline, Fusion will be unhappy if I delete that). On this idea though - perhaps there's a way to work that out, do the delete, then update whatever references got broken in that process? Anyone know?
I had one crazy idea to define my shapes in relative terms to some known point (e.g. the nose of the chord line), so I then can merely update all the dimensions - this kind-of works, but is *agonizingly* slow.
Another idea might be to try and find all the original points I inserted, and programmatically move them to new places - it might work, but could hit snags (e.g. if the user has added constrained rails or something).
Or... well... that's why I'm posting: maybe there's other accepted ways for an API to "change stuff it did in the past" to respect the parametric awesomeness that is Fusion 360?
Thanks for any and all hints/tips/ideas you might have!
Example: effect of scale on ideal wing shape:- 1 meter
Identical operating conditions, 10x smaller:- 0.1 meter
