export joints

Anonymous — Fri, 06 Jan 2017 13:56:28 GMT

Hi is there any way I can export a complete setup with joints to some file I can then read in my own application?

What application?

The answer, unfortunately, is no. None of the standard formats, such as IGES or STEP support any sort of joint definition. The only application that understands Fusion's joint model is Fusion itself.

Okay thanks, is there no other way like through the api or something?

Since USD itself supports joint definition, would it be possible to convey the relationship set in Fusion 360 in a USD file?

It seems that the joint types in Fusion and USD used for Omnivision/Create pretty much align. There's also a Fusion 360 "Connector" in development by Eric Bowman at Nvidia, previewed here: https://www.youtube.com/watch?v=EePFBWxSpUQ.

The UsdPhysicsJoint Class, https://graphics.pixar.com/usd/dev/api/class_usd_physics_joint.html, seems to encompass the joint types defined in Fusion 360. Is there any reason they can't be defined in an export?

Yes, functional would be the goal. I don't know how Fusion stores its joint definitions, but the open source USD API supports all the required parameters for a functional joint. There should be some way to map Fusion's internal definition for each joint, to that API.
