Issues with external linked componets.

Hey guys, I have a quick question.

I use Fusion 360 to design 3D printers as a hobby, and recently I’ve started working with more complex assemblies. These assemblies aren’t huge, and performance is generally fine. However, ever since the new update that introduced hybrid design, part design, and assemblies, I’ve started separating my workflow more.

Instead of using only hybrid designs, I’ve started using assemblies and creating external components that reference the current assembly. My issue is that when I first started, everything worked fine, but the more I’ve worked, the more it seems that Fusion struggles to compute everything.

Sometimes it loses reference geometries and I need to remake everything. Other times it won’t sync the assembly context, and I need to edit in place until it decides to sync. In some cases, it says everything is fine, but the external component has issues computing the sketch.

I’ve also noticed that sometimes when I activate the assembly context in a hybrid design, components shift around and then go back into place when I exit the assembly context. I think the components shifting might just be something I don’t fully understand yet.

I was wondering if anyone more knowledgeable than me could share some insight into whether my workflow is wrong, or if there’s anything I can do to improve it and avoid these issues. I'm more than happy to invite people to see my project.

I don’t think this sounds right - no file, pic or movie, - but,

Sounds like you did understand Hybrid, and that you changed away from good known flexibility, to limited stuff. Are you complaining - wishing to understand the new Autodesk madness?

Take Part file - only one component - ever! They turned off Assembly tools.

Assembly files - this is a file of imported parts. Edit in place alters the original with limited tools, if you want to make internal component, then it is now a Hybrid file.

Hybrid, same normal as it has been - was no need to change to other types, those, will add limitations.

Could be wrong.

Hey Dave,

Thanks for the quick reply.

If I'm working on a part like the one included in the image, which needs to be modelled with reference to other parts in the assembly, what would you recommend doing?

I'm currently using hybrid designs for such parts, but I’ve also just realised that I can create assemblies and, by using Edit in Place, create new parts that reference my original assembly inside the assembely i just created.

Which workflow would you recommend?

Hybrid.

That pic is (presumably) made up of internal and external components, - consider that nothing has changed,

just a lot of hoop la about a new process that has not been released to the public yet.

Frankly - they cut out stuff (common tools and workflows) in the Part version

You can make a single component Rule#1 file as Hybrid.

You can make Assemblies as Hybrid

Might help….
