Thread on many holes

[Lonnie.Cady]

Unless I am missing something, which is very possible 🙂

I have hole that I do a pattern on to create them.   However I have to create thread on each one manually and this get time consuming.

I tried to create the hole and then apply the threads and then pattern the thread and hole together but Fusion(OSX) locked up.

Is there another method to do multiple threads?

you should definitely be able to pattern the hole + the thread together.  You will need to choose "Features" as the Pattern Type in the Pattern dialog, and select the hole and the thread in the timeline.  I tried it on a simple case:

this was, however, on Windows.  I will try it on OSX when I get a chance.  This could be a Mac-specific bug.  Will let you know.

Thanks for posting this.

Jeff,

Thank you for looking into this.

I am at my shop and on a PC and it worked fine as you stated.

I will try at home on OSX later today.  It was a circular pattern with modeled threads. 

I got a couple of warnings about low graphics memory from fusion.  I wonder if the issues was related to graphics and trying to pattern modeled threads.

I had a chance to run in and try it on OSX.  Again, this is a simple case, so your problem could well be a bug, it just requires a more complex case to reproduce.

When you get a chance, and if it's OK, can you share your project with me at jeff.strater@autodesk.com, or send the design in a private message, and I can take a closer look.

Thanks,

Jeff

Thank you Jeff,

I am head home soon and will try it again.  I know it is going to work this time 🙂

Last time I actaully patterend the hole then added the tread and realizded I sould have patterened the thread also so I drung the thread in the timeline to before the pattern and then tried to edit the patten to add the thread.  I will test when I get home. 

Thanks for looking at this.

Yep it works 

It just must have been me.  I had things move back and forth in time line and maybe it was me who go confused.  I can say that with my iMac that creating the thread can be a little slow.  I seen the spinning ball or a little.  

I tried to patten the hole and thread and it worked great, I tried to create random sketch points and then create all holes from the sketchpoints and then add threads to all of them and it also worked great.

Sorry for the trouble!

Great!  Glad to hear that you are able to make it work now.

One thing that is worth pointing out, just in case anyone reading this is interested, is the difference between "cosmetic" threads and "modeled" (or physical) threads.

By default, when you create a thread in Fusion, it creates a "cosmetic" thread.  This is shown using some graphics textures that make it look like threads, but the actual geometry of the thread is not created.  If you use the "modeled" checkbox in the Thread dialog, you can tell Fusion to create the physical geometry of the thread.  Here is the difference:

Cosmetic threads can be useful for managing performance of your model.  The physical threads contain a lot of geometry that can slow down performance (both compute performance as well as graphics performance).  However, you wouldn't want to 3D print a model with cosmetic threads.  Sometimes people will use cosmetic threads early in the design, and only switch to physical threads as the design finalizes.

I am making a bread board 15 x 9 with 1" spacing of 1/4-20. I then add cosmetic threads. If I chose the "Identical" option in the pattern then the threads do not get added to all of the other holes; however, they do get added if I use "Optimized" or "Adjust". Is this how it is supposed to work?

in Early 2020, you have to select 'Adjust' as the array compute option, in order for the threads to be modeled.
