Fusion
Hi all,
I'm trying to align a part to a fixture using the edges of hole features and revolute joints with the API. If I create the joints with the UI manually it works. I was also able to create similar functionality to what I'm trying to do here using JointGeometry.createByPlanarFace instead of JointGeometry.createByCurve with slightly different code/models.
There doesn't appear to be anything wrong with either joint as long as they don't get added at the same time or if one is suppressed when the other is created. If you unsuppress the first joint after the second is made, it's works well too. I'm fairly certain I'm selecting the correct edges in the script.
The full error is "RuntimeError: 5 : A joint in system exsists for the provided input. Sytem will be over constrined with this input." All 3 spelling errors and all.
This may be related to https://forums.autodesk.com/t5/fusion-360-api-and-scripts/insert-and-constrain-a-component-at-differ... but I couldn't recreate an error after fixing their typo so I'm not sure.
Thanks
After running the script:
