Question about Threads

[moleary]

When I create a threaded surface, you can only see the threads when you click on the cosmetic id in the browser. Is this correct? Are threads in ProE stored as geometry and not textures? Also, I want to create a spiral thread, e.g. a screw. How do I create this thread?

Thanks for any help!

Threads are shown as cosmetic features (the purple lines). ProE does not actually create thread-like geometry. If it did, then imagine an assembly with 100's of screws and nuts and how long it would take to regenerate and redraw the features.

If you really want to make threads, use (in 2001) either a cut or protrusion using the HELICAL feature.

When I use the method you suggested, it appears to be geometry in ProE. The cosmetic thread way is a feature in ProE, but when exported to IGES for example, it appears as geometry.

Beacuse cosmetic thread are quilts, and will appear in your IGES as surfaces. If you export your model in STEP (solid) you will notice that there surfaces will not be exported.

For a realistic thread, follow Steve's reply.

From a practical standpoint, why would you need to model actual thread geometry? Sounds like a modeling exercise. We keep it simple and simply create a simple hole (diameter=major of screw thd) and call out the thread spec using a leader. We abandoned cosmetic threads long ago because they simply weren't worth the trouble!

Sometimes, it's important to model the actual thread. That is, when you need something that is not a standard and the details of the thread form needs to be spelled out. I'm a new wildfire 2.0 user. Coincidently, I need to figure out how to model a thread. Hopefully, I can learn wildfire quickly to the level of knowing how to use the Helical feature.

I forgot the mention that cosmetic threads do a good job of graphically polluting a busy assembly that may have dozens of threaded holes in the parts within.

This is true, but it makes for a great photorender...

While a true engineering model does not need the threads, really, it shouldnt have them at all, something for the marketing folks would look great with the threads shown.
But if you have time to work for the marketing people, your engineering manager isnt giving you enough work... haha.. have a good weekend everyone
