Slow performance & crashes
@BCAdair It seems you are experiencing the same error repeatedly based upon the submitted reports. I suspect this may have something to do with projected sketch geometry, but I will need to investigate further to be sure. Would it be possible to share the design you are repeatedly crashing with?
You can create a public link of the design and share it here or e-mail it to me at nathan.chandler@autodesk.com.

@MartinMajewski Since the June 20th release, I find only 3 error reports submitted from your e-mail address. When you send in the error reports is the e-mail address filled out?
These reports can be very useful to decipher what is happening.
As a generic tip, it may help to review how to optimize settings in Fusion 360 for performance.
An additional tip may be to note which video card is in use when using Fusion 360 via the Graphics Diagnostics command in the help (?) menu. For systems with dual graphics cards, it may be helpful to modify the energy saver settings.
For the below scenarios:

- Sketching a simple outline (eight line segments, fully constrained), extruding it and having a path pattern modifier (why can construction lines not beused as paths?) on that object in one direction (making 10 adjacent copies) slows the whole application down a lot.
- Copying that 10 objects 10 times in a second direction leads either to the first crashes or slows down the application that much, that you can grab a cup of coffee while the beachball is spinning.
- In the case that Fusion 360 recoveres from the duplication terror the viewports becomes laggy as hell. I'm not speaking of a low framerate. I'm speaking of a delayed display of every command or mouse move I make. It's like watching a deja vu. If for some reasons that state recoveres, everything is smooth again. But at this state Fusion is just a viewer tool, every other command will slow it down again or make it crash.
Do you have the sketch constraint preview enabled? Could you provide a screencast recording of some of these behaviors? From the above descriptions, I'm not able to discern the reproducible steps.
Note that if being able to use a construction line as a path (in a sweep or loft), could be a good Idea to add to the Fusion 360 Ideastaiton.
Thank you in advance for your help! I hope we can get to the bottom of this quickly.

No, I use the "pattern on path" tool to achieve this:
This modell originates from this sketch
Yeah, I have the preview option for sketch coloring activated. I turned it off now, restarted Fusion 360, but the performance is bad anyhow.
Indicating if a sketch is fully constrained (AND what parts are not!) is crucial for me, so I was impatiently awaiting this feature - having to turn it off again hurts bad.
As you can see there are a lot ob components inside the browser. This is because it is not clear for me how to organize my modell with Fusion 360 and it could be the reason for the performance loss. But having everything combined into a single object feels not right and makes problems when modifying the sketch afterwards, because of history-dependency issues. Hiding the generated subobjects is also a lot easier when you don't have to select every object seperately.
Maybe I miss something, but I can not see a feature like "Array pattern" or something similar that would just perform a clone by reference operation where only one object is hold in the memory and the others are just instances. 3ds max has this option for decades now...
But maybe the pattern tool does exaclty this only in an inconvenient and inefficient way?

Hi Martin,
I tried the similar workflow on my Macbook pro, seems I did not find obvious performance degrade. I used "Pattern on path" command and select new extruded component as input, I select one edge of the extrude as direction, copy 10 components. Then start patten on path command again, select another edge as second direction, copy 10 components again, I still did not find obvious lags.
Could you help record a video to show your problems? You can post it here or mail to me via weining.cao@autodesk.com. I am afraid I may not follow the exact steps like you. There might be some other special factors affecting the performance.
By the way, I have another question to you: Why don't you try rectangular pattern to finish your task? Usually "Pattern on path" is suitable for pattern on a special path like spline curves, etc. Maybe in this case, a rectangular pattern would better serve you. Can you see similar performance degrade by using rectangular pattern?
Thanks,
Frank
