Solid threads

[CamHead]

Does anyone know how to quickly create a

threaded hole representation in a solid?

Thanks

I model the thread as a revolved surface. To model it as a true helix is almost impossible in any solid modeler, and would consume too many resources anyway.

 

If you model it as a revolved surface, you can see the thread form (when in a cross section view) and when viewed from almost any other angle, it presents a pretty good optical illusion as a helix.

To model the true helix as a solid is very system intensive. Not really worth the effort if you ask me. If I HAVE to see threads, I'll draw the correct number of teeth/pitch and do a revolved cut.

CamHead, is this what you want to see?

ProE will make solid threads in one click. When creating a hole all you have to do is choose screw size (1/2-13, 10-24 or custom) and put one check in the box for true threads and bingo.

 

Also you can draw a triangle, create a helix from it and then subtract it from a straight hole. Takes twenty seconds to do if you have the triangle that represents your thread.

Beav - You didn't add that Pro/E makes a "Cosmetic Feature" for a threaded hole "representation". It is not the true helix that I think is what the question asks.

 

At this current time that functionallity is Vapour Ware... Maybe in the next 3-5years.

CamHead,

 

I have designed a 3/8" - 16 thread as a solid body if you're interested. I have uploaded it to the FTP in two different versions. It only took a minute to generate the solid after the geometry was created. My computer is a P3 833 MHz processor using Win 2K Pro and 256 Mb RAM. There are two files, one in the MC8 folder and another in the MC9 folder. They are both .zip files with the same name, V9 added on the .mc9 zip file. The name is "3_8-16_Thread". It isn't cut into a hole but will give you an idea of how to design a thread using Mcam Solids. Jay's thread image is good to look at. With the .mc8 or .mc9, you can delete the solid and see how the geometry was created. Have fun.
