Running Slow as design gets more complex - How Can I improve this?

[men8ifr]

My design has maybe 10 components, 10 Sketeches, 1 Mesh but over a period of time it gets to a point where most operations are taking a long time e.g. delete a line from a sketch an CPU fans are working overtime while Fusion has a big think about things. 

What can I do to improve this?

All components are fairly simple but I do use/need a lor of dimensions/comstraints  (upto 50?) in the sketches. 

All other components and the mesh are made non-visible

I tried copying the components I'm working on and pasting in a new document thinking I could then delete the old and re-import the revised component when I'm done but the paste does not work. 

I thought I could delete some components to try and see where the issue is but I don't think delete will work - at least I should use remove but all the history is stil in the time-line so I don't think that will help.. 

I could turm the time-line off but I don't want to loose all base sketches etc

It would help if I could work out why when editing a simple sketch it is using so much CPU? 

I'm currently on a trial for a subscription - is it worth contacting Autodesk? 

I can't attach the file it's too big 128Mb - probably because of the scan. 

My Laptop is 11th Gen Core I7 32GB Ram fast SSD etc so shold not be computer specs.

Hi,

If you only have 10 components and a mesh but it is 128Mb, it sounds to me that your mesh is what is slowing things

down. What are you actually trying to do?  It may also be a workflow issue. Are you using the move command a lot?

Unless we can actually see what you are doing it is a bit tricky. How about some screenshots of the model and the

timeline. At least we can get an idea of what might be happening.

I suspect that the mesh has so many faces that fusion is doing its best but just cannot calculate fast enough.

Option B is that your sketches are too complicated. 50 dimensions and constraints are not a lot but as a general

guide you should use simple sketches and then use the tools to sculpt. An example would be fillets. I can put fillets

in a sketch and extrude it or I can make a basic sketch, extrude it then put fillets on with the fillet tool. The second

method works better in most cases.

Cheers

Is there a way to remove the mesh to test? I should say the mesh is used for some mesh-sections that are used in some of the sketches. 

FWIW I do use the reduce tool to reduce complexity after initially importing (time-line is switched off at the start of the file/when editing) but felt more reductions were giving up some detail. When the mesh is imported and for the first few components Fusion ramains fast only later does it slow-down.

Sceenshot for this sketch and time-line

Please attach your model.  Open in Fusion, select the File menu, then Export and save to your hard drive.  Use the Attachment section to attach it in a reply post.

It's too big - 128mb. That will be due to the 3D scan mesh I expect

[TrippyLighting]

A large mesh, mesh section sketches, not fully defined sketches, move operations, position capture operations, yellow warnings in the timeline all contribute to this.

Looks to me like you bit off more than you should chew!

Well I can fix yellow warnings - but what else can I do? 

What else should I do in the future.
