Performance degrading with last few updates?

Performance degrading with last few updates?

I was working on a complex file in January (file is attached) and editing was a bit slow waiting on some sketch edits but kinda expected, otherwise it worked just fine.  I put the project on the back burner as it is a personal project and the machines were all booked for a few months but we are catching up now so opened it back up.  Over the last couple months though, it has felt like fusion is getting more bugs and less stable (same across multiple computers, accounts and files) and with opening that complex file again it is VERY slow and wants to crash with just about any change.  What are all the settings that can be changed to increase stability and some performance?  I know of the graphics diagnostics one to limit effects but that changes nothing for me with an RTX 2070 and most of it being sketches but thats the only performance setting I'm really familiar with.  I did some forum searching but didnt find much relating to general performance lately but feel free to link any you know of that might help.  Thanks.

Hi,

I opened the active sketch in another application and found that it is very "awkward" in parts. I will analyze it in more detail during the day and optimize it if possible.

Ya I started it early on when I was new to fusion and it is very messy but it will be a one time use so dont want to spend a lot of time fixing the sketch.  As I mentioned, it was working fine before just a little slow but is now very slow and very prone to crashing.  My idea of a "fix" if there are no settings that can help will be to duplicate the file and have a new file for each sketch and delete all but one sketch for each of them so i have one sketch per file instead of 10+.  In January it did help to hide all the non active sketches but does not seem to be helping much now though.  Thanks for the reply.  Mostly hoping for settings changes that can help with performance in general as fusion has gotten slower and buggier this year but anything is appreciated and will be tried.

Hi,

The problem has nothing to do with the application but lies in the miserable quality of sketch 31.
As you can see on the screenshot, there are 9 control points in a range of 0.02 mm.
This must inevitably lead to problems with extrusions.

In the future, create sketches in Fusion instead of importing them.

What would cause the program to be much less stable now though compared to 7 months ago?  The only change since then is updates.  It was working fine, albeit slow, in January and when I opened that file yesterday it was freezing and crashing fusion just looking at the sketch before I even made a single change.

 

The imported sketches are .svg files and really dont want to trace them all manually(unless there's a better way to import them with fewer line segments?).  I figured the very poor sketches in that first file were causing issues but would not expect a performance change without doing anything.  I have also reinstalled fusion a few times so far this year and the last time being 3 weeks ago but it didnt help anything.

 

I have even noticed performance changes in files as simple as the one I am now attaching here.

I can't find any limitation in editing the sketch.
Can you show the behavior in a 'screencast?

Of all the sketch imports, SVG is the one that causes the most problems.

Imported sketches do not have any specifications (dimensions, perpendicularity, tangency, centricity ...).

And that is what is slowing down the system.

If you find creating sketches in Fusion too "cumbersome", you will have to live with several problems.

No specific problems with the file but just fusion in general.  The other guys in the shop have also mentioned the same issues on their computers(each computer is different).  I can repeat some of the problems though I have not done a screen cast before with fusion,  is that something that is built in, and does it capture the full window not just the work space?

Look once for various free aps.
Formats are usually selectable.
The result should be saveable in mp4 for uploading.

Sorry, I misunderstood, thought you meant something else.  Here is the easiest to show example.  Closing any file makes the full screen go blank, parts of other menus show up then finally goes back to normal.

Another performance issue I've noticed lately is it takes longer just to start fusion than my computer takes to do a full shutdown and restart.  (25 seconds for fusion start up only, 22 seconds for full windows shutdown/restart)  It didnt use to take near that long.

Use the most computationally efficient modeling techniques.

Symmetry constraints are relatively computationally expensive and often not needed.

You are using very very computationally expensive modeling techniques.

TheCADWhisperer_0-1687985610471.png

This should be a simple 2D sketches - not a 3D sketch.

Dimensions that cannot be measured in the real world?

 

Move is almost always the wrong move (pun intended) as used by beginners.

 

Fish scale sketch is extremelyyyyyyy expensive - Pattern Features - not sketch elements.

Biggest mistake so far in the file.

Many other expensive sketches

 

TheCADWhisperer_2-1687986064957.png

 

Another very computationally expensive sketch - do not use sketch patterns (except in rare cases and very simple).

Unresolved issues highlighted in the Timeline.

 

TheCADWhisperer_4-1687986220732.png

More sketch patterns that should be simple sketches with feature patterns.

 

TheCADWhisperer_5-1687986266425.png

and more...

 

TheCADWhisperer_6-1687986342349.png

Why create simple lines and arcs with hundreds (thousands?) of short little lines.

 

 

I recommend that you start over.

Attach your new work here after each and every sketch/feature for guidance by the experts on most computationally efficient technique.

 

Blue lines and white dots should keep you awake at night.

Ask questions early and ask questions often...

How did you get the dimensions to stay when removing the other half?  I've been using mirror to quickly get the full drawing in 2D and then be able to use diameters in dimensioning.  I know I can just add /2 and dimension the radius but when we make a lot of the same thing and constantly change dimensions, its easier to use the same number on the drawing and see that it matches at a quick glance.

Ya, I made all that when I first started using Fusion 360 2.5 years ago and have simplified stuff a lot since then.  I am almost entirely self taught through trial and error(learned about dimensions from a co-worker) so I expect poor performance from my old files but not the stability changes.

I have no idea why the numbers are different for you here.  I input all fractional inches to the nearest 1/16.

edit: never mind, those are metric numbers for metric threads.

Toggle axis line to Centerline type to get diametral dimensions. 

There are tons of little tricks like this that might be hard to discover on your own. 
Right click everything to find lots of goodies.

Found that center line thing now and will definitely be using that and looking for more was like that to increase efficiency.  Thank you.

 

 

Back to the original question though

And I'm not meaning to fix issues with that first file but just performance improvements in general.

Finally got an answer somewhere else and it is no.  The only performance setting is that graphics check box.
