Thread made by using command "Thread" does not render, bug or feature?

[Anonymous]

I realized that when I make a thread by using the command "Thread", the thread does not render. When I make a thread by modelling a coil and use that as tool to combine/cut, it renders just fine. Furthermore it also does not take the  appeareance

Is this a bug or a feature? If it is a feature, can someone explain me what it is used for? For drawings? It is not needed for CAM because you can choose to cut a thread by toolpath in the CAM workspace.

If it is a feature i think it would be great if there was some documentation in the corresponding tooltip.

Appreciate your help, thanks

In order for a thread to be rendered, you'l have to set the check box for "Modeled" in the thread creating dialogue.

Also, you might want to select the body/component, right click on it and select Display detail control. Set it to fixed/high in order to eliminate the visible tessellation artifacts of the geometry.

Thank you very much! I did not get that one... Also for the tip to improve the tesselation artefacts. I saw the menu point before but did not realize what it was

I rendered it again, following your advice. Looks better, indeed! I have a follow-up question I hope you can answer as well...

I did not measure it, but I don't think it took any longer to render with "Detail Display Level" set to high nor was the handling of it in the model workspace more demanding. Of course, it is a very simple model so I'm not really surprised by this.

My question is, in which cases would you use these settings and are there scenarios, like large assemblies, where you would not recommend to use high settings? Does it have much influence on a design containing mostly straight edges with just some small curved or circular features?

Thank you very much again!

If you've got enough RAM in your graphics card you should be fine. This should not affect render performance negatively  as it simply increases tessellation of the object.

This is not only, but mostly notable on long thin objects where you focus in on small details and you should limit this to objects where it is visible.

The LOD (Level of Detail) algorithm in Fusion 360 works on an object basis and sometimes for such objects it needs a little help.

I just built a new PC on the information that Fusion 360 does CPU only rendering (besides the viewport rendering which does not put more than 50% load max on my GPU)...

My graphics card has 3gigs of ram, pretty old 2013 Radeon R9 280x, overclocked by 15% but definitely the bottleneck in my Ryzen5 1600 setup (running at 4.19 GHz, 32GB RAM at 2933MHz). I am not into gaming and use my PC mainly for Gimp, Darkroom, Fusion 360 and very little video editing, so I wanted to safe the money for a new graphics card (may change in the near future, there are no good drivers around for Linux anymore...).

Are you using something else, more elaborate for rendering? I think it is less then a year ago that I started using Fusion 360, attracted by its CAD/CAM functions. Got interested in rendering my designs just recently. I like the possibilities it gives me more and more so I am very keen to learn more about it

No, I don't use anything sophisticated for rendering. If your graphics card has 3GB of dedicated RM you should not run into trouble with Fusion 360.

Thank you very much for your help!

Hi,

Am I missing something or did Fusion remove the MODELED option in HOLE feature? I am trying to create NPT threads and then print them but I have no options to model it and it renders zero threads?

@RufusToad The thread tool does not have the option to model tapered threads.
