Bad allocation error

[Makingmike]

While modelling in the sculpt environment using the edit form tool, I have repeatedly encountered a 'bad allocation error' the program freezes for a few seconds the closes down often causing other programs to malfunction (especially annoying when several hours into a 3D print). Recently it has caused my computer so much trouble as to disable the GPU forcing me to restart my computer, and once even having to reinstall my graphics driver.

I don't think its for lack of hardware as I have a GTX 1060 6GB with 16 GB of RAM.

I am trying to model a human heart, I'm new to fusion 360 and t-spline modelling so maybe I'm doing something awkwardly?

Hi @Makingmike

Sorry that you are facing trouble. 

Can you please record a video of the situation? It will help us to understand it more.

I tried your design part file and it's working well for me. 

You can try below things to reduce graphics overhead

- Enable better performance mode from 'Sculpt' >> 'Utilities' >> 'Enable better performance' 

- disable effects from 'Navigation Bar' >> 'Display setting' >> 'Effects' 

- switch to Selection display style as 'Simple'  from 'Preferences' >> 'Graphics' >> 'Selection Display Style'

Thank You!

I reckon the expectation of burdening your system with non-Fusion processes while working with the program is unrealistic.    You might be able to successfully blend cocktails in your parked Corvette- but at-speed while cornering?   Expect spills.

Here's a recording, when fusion crashed and the screen went black, some programs could be used (I managed to stop and save the video) but I couldn't open the start menu and had to turn off the computer from the button.

I had the task manager up because the memory might be the limiting factor as it does get very high at one point.

I understand that I should enable performance related settings and close other programs etc but these crashes seem a little catastrophic? shouldn't fusion just slow down when memory gets low?

I'm no expert.   I doubt you'll receive any actionable feedback on why your specific system froze- there are just too many context dependent factors.  

That said, in my case, when taxed, Fusion may become unresponsive, Fusion menus blacking out, the entire view port area and menu bar white, with any attempt to interact eliciting a windows prompt asking if I want to wait or kill the process.    At such times, graphic anomalies from the Fusion environment litter my desktop.   Rarely, the opening/launching of other assets becomes unresponsive.    At such time, the Task Manger does not report a consistent connection to high CPU, Memory, GPU, or Drive use.

Of course, my combination of hardware and software differ significantly from yours- as does everybody's.    Always the conundrum.    It is for this and other reasons my best advice- other than updating drivers, which you've doubtlessly done -is to run no other application concurrent with Fusion.   Eliminating contributions to failure is a troubleshooting first course of action.
