Large assembly performance, Disable Automatic Refinement | Autodesk Inventor 2016

This setting doesn't exist in Inventor 2015 and earlier. Quick tip, a new setting in Inventor 2016 let's you lighten the load on screen and hopefully make your Inventor run that little bit smoother. Disable Automatic Refinement for large assemblies in Inventor 2016.

Great video, I have just discovered your channel and have been binge-watching the whole afternoon. Just one interesting addition to the video, what if you then want to refine the edges after you zoom in? If you disable automatic refinement it will enable an option "Refine Appearance" in the "View>Appearance" ribbon, it works like the "Regen" command in AutoCAD. Then if you zoom in and want the circle edges to be refined you will have to do it manually by clicking the Refine Appearance option. This works for me, as I'm currently testing some Inventor features in my not so powerful home PC, and having the automatic refinement disabled does improve the zooming and rotating actions.

Hi, when turning the auto refinement off when zoomed in, the immediate geometry won't change appearance as it is already drawn on screen. Further zooming will show the straight edges. Since this is a performance enhancement option redrawing the already visible smooth geometry with straight lines when the box is ticked would add further unnecessary load to the graphics. I'm no expert but that's my theory.

I thought that too, I didn't do it during this vid but I panned around to other off screen geometry and it was all just as smooth, the entire thing was barely different to smooth. That would definitely explain the objects I had on screen at the time but off screen geometry you'd think would be... non-refined? If that's even a word haha
