speed troubles - move command

[kCPZE3]

I have a huge import assembly file and am creating exploded views for renders.  Moving any piece of the assy is taking exorbitantly long - like 15-20 minutes from picking to getting locators to perform the move command.

Any ideas?

thanks in advance!

Hi @kCPZE3, 

Thank you for reporting this issue. 

I remember that we have some performance issue with importing large assembly. (not native Fusion file)

Our development team are aware of it and working on it. We apologize for any inconvenience 

So far, A great workflow to improve the performance of Fusion 360 while working on a large assembly would be as follows

• Simplify as much components as possible by deleting bodies and faces
• Re-model imported SolidWorks files where possible
• Use Selection Sets to Hide not important components
• Reduce the number of features by a scroll back in the timeline

To find a workaround, could you share your design with me? Here is how to share it (my email address is "ahreum.ryu@autodesk.com")

I look forward to your reply

Many thanks, 

Ahreum.

Thanks!

I'll be sharing the file and look forward to further insights.

Can you define "huge" in terms of number of components or complexity of geometry ?

[kCPZE3]

it was a 276mb STEP file import, does that help? I'm not sure how to get
an entity count in Fusion.

[TrippyLighting]

If you open up text commands:

And then type : component.count 

you'll be presented with info as shown in the screenshot below. But in genreal this sounds like your design has several thousand components. Does this involve PCB's ?

[kCPZE3]

Peter,

Not sure if this is helpful, but I have 3 other assemblies of similar or larger size that are slow (understandably) but workable.  Similar parts, SW files.

thanks,

[TrippyLighting]

Did you enable the timeline after importing the geometry ?

Hopefully you have not 😉

[kCPZE3]

I got the text commands window up, but it wouldn't recognize the command, count or counts.  See attached.

thanks again,

[kCPZE3]

no on the timeline.

yes, PCB's on all imports.

hope this is helping ---

thanks again,

Kent

success!  I found the radio buttons on the right, txt,py,js...

890 bodies.

[TrippyLighting]

As this is for rendering I guess hiding things is not a good approach but things that you don't need to select as individual items you should put into a selection set and then set all this components/bodies in the selection set to unselectable. So all the passives, IC's etc,anything that you don't need to select for moving it around you should set to unelectable, or even hie it, move the assembly, e.g. the entire PCB and then unhide.

If you have 890 components/bodies that is really not bad at all. However if any of these are mesh bodies that can also substantially slow things down. Sometimes imported PCB components can be meshes turned into solids and the high facet count starts having an effect. Hiding or setting to unselectable can help here as well.

[kCPZE3]

Yeah unfortunately I need all components for the render.  Good to know that 890 isn't a huge component count.  Nothing is mesh, all are bodies.

I really appreciate your comments and thoughts.
