Display error after Cut Body action

[g-andresen]

Hi,

in the German forum a display error was described, which I would like to represent here.

this does look like a graphics bug.  In the screen shot below, I changed the body on the right to a "high" display detail level, and that seems to have fixed it for that body.

can you explain how to do that?

right click on the body - it will be in the context menu.

That fixed the original problem 🙂 @g-andresen a big thanks for re-posting in eng-forum + @jeff_strater you are the man of of the hour.

Hi Jeff,

thank you very much for the hint.
This is a setting that was never necessary for me until now.
I have noticed that the behavior described only occurs in the "Adaptive" option.
"Fixed" does not show it in any of the 3 options.

I explained that in the German forum (in Germish) where this originally was posted.

So here it is one more time in English (so I can reference it for future use).

All computer graphics programs (system) regardless whether that is a CAD program such as Fusion 360, SolidWorks, Blender, Maya etc. at some point in time have to convert geometry into a triangulated mesh in order to display this on a Monitor. In the computer graphics Industry that process is called Tesselation.

CAD software traditionally uses BRep and NURBS mathematically precise descriptions of geometry to represent geometry internally.  Fusion 360 uses by default uses a LOD Algorithm (Level of Detail) to convert that mathematically precise geometry for display purposes. 

In Fusion 360 that LOD algorithm works on an object basis. So objects with curved surfaces that have a high(er) aspect ratio and have (read, thin, long) suffer from tesselation artifacts, where that triangulation becomes visible.

As @jeff_strater has already pointed out, this LOD algorithm can be overridden by setting the Display detail control to fixed/high. 

Anyone who uses the Zebra stripe analysis tool should always set the Display Detail Control to fixed/high.
