Hello,
I'm new to using joints and animation in Fusion 360. I have a model of a Hopper Car used in Model Railroading.
I would like to have this model follow the rails. I would like to be able to curve the rails left or right and up and down
and have the car follow the rails. Is this something that can be done in Fusion 360 or some other software?
Thanks,
Don
Please attach your model so someone can show you the process. Following the straight rails is possible, I am not too sure about following curves. If you do not know how to attach your Fusion 360 model follow these easy steps. Open the model in Fusion 360, select the File menu, then Export and save as a F3D or F3Z file to your hard drive. Then use the Attachments section, of a forum post, to attach it.

I was expecting to receive an assembly model with Joints, but no, you send me one with just components. I went ahead and added joints to one truck. As you can see in the video the wheels are turning in relationship to their motion along the rail. If you have any questions, let me know. Model is attached.

Do you think it could follow this test track? In front of the hopper, the track curves right then left. Behind the hopper the track curves up then down. Included the model with the track. Sorry no joints yet, working on it.
Hi Mr Doleksa,
As you have been advised by the Expert(s), F360 doesn't handle kinematic-rich structures very well. As a matter of fact, not too many software do. The problem is at least two-fold. The respective algorithms and the math behind them are neither simple nor easy to implement. The other issue is that it is questionable to implement them in a real-time interaction scenario on the standard hardware. It might be reasonable to mention also … that the price level of Fusion Ultimate might not support the development-related expenses … hopefully only yet.
Having said that, please find some samples (I hope entertaining) of the development I committed years ago.
In the case of the problem 'Train in the track' movement animation ... I will politely say that your 'desire' to achieve such effect in F360 is excessive 😉 ... but if you have some spare change of perhaps x00K $, ANSYS or similar heavy weights could be the options here. Contact respective sales departments and ask for the quotation.
In the meantime, consider adding quite a few of DOF to your wagon bogies as a possible in Fusion development step, allowing it to travel on a curvy track.

To be viewed on 4K media devices (monitors, UHD TVs, projectors...) of reasonable performance. For the best experience, use stand-alone media applications (WMP, VLC) and the native resolution 3840x2160 - full screen. The '_arcd' files require an anaglyph red/cyan glasses, while '_al' is for an active shutter glasses 3D hardware (~30 deg viewing angle is recommended). Download the files over a network, where the cost of doing so is not a concern. The files are to be used for private, non-commercial purposes only.
