Hello,
The feature you are trying to create can be done using the combination of helix and the sweep feature.The attached jpeg shows the features needed for creating the threads. I hope this helps. If you would like to have the SW model sent to you, send me an email address. Thanks.

oxymoron, here is my email: mannepal@yahoo.com

Thank you !!

No offense guys. Thread shown above seems like to be a spiral object. Will it fit with it female parts? It seems more like a drill bit rather than thread.

Model emailed. Thanks

the sketch should be perpendicular to the helix starting point. then it will look like a thread. right now it is zero thickness.

Oxy..could you tell me how to start the helix from the tip of the cone. I am not getting it.
I have added one model here.

AP:
Normally the thread does not start from the tip. It start from a portin bit below the tip. You need to have a circle (sketch) for the helix. Thanks.
