Horribly Slow And Inefficient
Hi @Anonymous,
Thank you for posting in the community!
Sorry to hear that is happening! At this time I suspect there might be something related to network connectivity. As the quick test, can please you switch Fusion to the offline mode, by clicking the "clock" icon and turn on the "switch", and see if this makes any differences? If so, I would recommend checking the suggestions in this article.
Did this happen with a paricular design or any design files? Would you mind sharing one of the design files with me? If it is fine with you, can you please create a public link to the design file and post the link in this thread? You might like to send it directly to me ([email protected]).
Also, could you post your System Info (OS version, GPU, RAM, etc)?
Finally - within Fusion, please go to the help menu (the "?" icon) - Support and Diagnostics - Graphics Diagnostics, and see which card Fusion is defaulting to. Please take a screenshot.
Please keep me updated!
If you have any questions, please let me know.
Thanks.
Perhaps you can share some of the design that exhibit this problem.
There are all sorts of way you can share information. Screenshots, Screencasts, sharing the model.
May of the situations arise because users use workflows that might be OK in Sketchup, but not in a CAD application.
scale seems to work pretty well for me. I don't see any long lags in this operation. You have two different components here, overlapping. Is that intentional? I assumed that Component2 is the one you want to scale.

I did not turn the model around to see that Component 1 was the back side. I understand the workflow now.
I have the "UI Preview" turned on, which changes the toolbar into a tabbed version. But, the commands underneath are exactly the same.
If you have evidence of bugs, please provide it, so that we can fix them. I did not encounter any bugs in working with this design.
Here is how you achieve what I think you want to do:

Thanks. I think the modify -> combine step was key. Ok, I will continue to open issues as I come across them. 
Don't know why is super slow and laggy for me though. Fusion 360 does technically work, but instead of having the paintbrush in your hand it feels like you are skyping with someone 1000 miles away, telling them how to use the paintbrush.
It is very precise but weird too.
hmm this is my machine, and I have ULTRA lag.
You are working with a second external display on an onboard graphics card with relatively low memory (for working with 2 displays).
Does your machine have a dedicated graphics chip ?
That of course is only relevant if the lag is a viewport performance problem.
Are you seeing thins lag also with the model in this thread ?
Can you disconnect your external monitor and verify if you still have lag ?
If you look a the machine specs I posted in the first screenshot you see the Intel HD Graphics 630 with 1536 MB memory.
That is the integrated graphics chip built into the Intel CPU. The memory is "shared memory" meaning the graphics chip basically uses part of the RAM available on your computer.
The second screenshot shows a AMD Radeon 560 Pro with 4GB of dedicated graphics memory. This is a separate graphics chip that is much more performant than the integrated Intel graphics card.
