Is there an easy way to create threads on autoCAD 2005? Iv'e toyed with several ideas, but they all fail. Being that im about 2 weeks new to Autocad, i blame it on my newbieness, however, ive bought 2 autocad books, and taken 3 online tutorials and still fail to see anything on making threads. I.D., or O.D.

Any Help would be great.

As a side note, I can work in 2d and 3d, and would like to know both 2-d and 3-d methods.

Thanks for any help!

You should be able to find a lisp spiral generator for download somewhere. Create the spiral, and use it as a path to extrude the threads. Putting threads on a lot of screws will slow AutoCAD down pretty fast.

Try CadDepot.com for a spirial generator. :idea:

Like Gerry said, threads will slow down your drawing. I don't know an advantage to drawing them unless you are designing or analyzing the threads.

When I want to represent a tapped hole in solids, I use a cylinder for the minor diameter that I subtract and then I place another cylinder for the major just below the surface. The solview/soldraw commands then show the hidden lines correctly.

yes, i see how that would be easier, and to be honest I would never build threads on a print. Its simply for personal projects i make, as a hobby. all the threaded parts i design are 2d currently anyways.
