I know ArkanceSystems (again thaks to @Anton_Huizinga) has a node for this but I want to tinker myself to prototype more functionality.
Its a pain and you have to be careful what python engine to run in, for me on C3D 2024 its IronPython 2.7 version 2.5 that works, I think:) although all it returns is no solution found invalid parameters??
Anyways here is graph and python code, if you get a chance to experiment, the problem is not the code i think its getting correct parameters to work with the geometry, and assistance from the community on getting a template for what works, what does not would be great, thenks.
cjm
Please note I did hard code some parameter values into this as just testing different ideas, so maybe they need changing??
