Thread Tool

Thread Tool
This tool allows you to draw male threads in the top and side views. Tapered threads are limited in length to 70% of the thread OD. That's a little bit more than the normal effective length for pipe threads.

If you choose Outline, then the Outline style is used around the outside of the threads. If you choose Opaque, a white-filled object covers up objects in the background.

To use the tool, you just click and drag.
