Disappeared components on opening model in Fusion 360

[Frans.Hessels]

When opening a model in Fusion 360 some of the components don't show up on the screen. Scrawling back to the feature (in this case extrude) and step by step going to the end of the timeline again the components show up again.

(see the image). In an other case when combining a solid rectangle cube with 12 tubes around 12 cylinders the lower row of cylinders can't be seen on the screen but can be selected. The inner cylinders in the tubes stay visible all the time. Working in Windows 10 with a NVidia Qaudro P5000, driver 442.92-quadro-desktop-notebook-win-64bit-international-whql.

Can it be there is something altered in the latest update? Never had this before in Fusion.

Can you please share a copy of the design or a link to the design? It will be easier to find any problems if I have the data.

Hello Phil, send you a PM. Frans

Thanks for the model. There appears to be a faulty extrude. 

Extrude 3 is removing the pipes. They appear on the "objects to cut" list, and there is some inconsistency about how they participate in this extrude. This looks like a bug.

Remedy:

1. Open the design.
2. Edit Extrude 3, change the "objects to cut" list
   1. Add the pipe bodies to the list, and then remove them, all in one edit.
3. This might cause a downstream sketch and sweep command to give an error, but it looks like those can be fixed by adding back some references that have been deleted in step 2.

Hi Phil, the extrude/cut function I deleted and there were no more problems downstream. Opening the model after saving is executing fine now. Thanks for your help.

Thanks Frans for the update. This is one of those cases that are really hard to diagnose without knowing exactly when the bug occurred, such as at what step or combination of steps.

Being that your workflow (which is fine, it's not the problem) has revealed this once, perhaps it will reveal again. If you ever notice this again please let me know. More examples are good.
