3D multilayer PCB capabilities?

[javiermail89]

I'm trying to desing a 6-layers PCB and, in order to export it as a .step file, I see that you have to transfer it to a 3D PCB first. However, only my top and bottom layers seem to be on the 3D menu when I select that option.

Looking online, I ran into the question linked below, where it is said that Autodesk Fusion had no multilayer PCB capability as of 2020.

 Is this still the case? If so, is there any other way I can export my PCB as  a .step model, for it to be used in CAD?

Thank you for your time.

Hi @javiermail89,

I hope you're doing well. You don't need to break it down, remember that even those the overall impedance of the trace increases with it's length, the per unit length impedance stays the same and that is electrically what's used for simulations so you don't have to treat each segment individually. If you ever use the signal integrity extension or another field solver you'll see that this is how a simulator can take the entire trace into account without having to individually assign parameters to each segment.

With that said, there is currently no mechanism in the 3D PCB to break up the traces into multiple individual traces as far as I know.

Let me know if there's anything else I can do for you.

Best Regards,
