symbolic internal threads

Hi, I was wondering if it was possible that whenever I create a threaded hole, that symbolic threads are automatically added to it. Because I to 95% of my work on the CAM side I add a lot of chamfers to my parts and the little dashed line around a threaded hole becomes hard to see sometimes. Also, is the thread command able to create internal threads? I have only been able to make external thread like on a bolt. 

 

Thanks.

It sounds like you're creating a simple Hole feature and then adding a Symbolic Thread feature.  That's the old way (from more than 10 years ago).

 

Now, when you create a Hole feature, you have the option to create it as a Threaded Hole, which will automatically include the Symbolic info.

I'm using the hole command but the threaded holes visually look just like simple or drill holes. It has that little dashed ring around the hole that indicates the major diameter of the threads but that can be hard to see and isn't really that helpful...

While in Modeling, that's all there is to a Symbolic Thread.  In Drafting, when creating Drawings, you have more options as to how Threads are displayed, but in Modeling, what you see is what you get.

I assume you can create detailed threads, but then your model will be more complex.

I'm probably wrong but I swear I've seen or even made symbolic threads like in solidworks one time. O well.

Ya detailed threads in CAM slow everything down and sometimes make selecting holes a pain.

Agreed, our CAM guys have complained about detailed threads multiple times, and I have finally convinced all of the designers that symbolic threads are all you need.  Detailed may look "cool", but they weigh the file down, and make life harder on the machine shop.

 

Now, if Siemens can just get an external thread tool, that works like the threaded hole.  Dimensioning external threads frustrates our new NX users Smiley Happy

I guess you have figured out that the Hole command does create dashled lines to display the internal thread. The issue is being able to see the dashed lines used to display the thread, because they are inside the solid body. If you make the model translucent it helps.

I agree with everything you said.
