Polygons and Instruction...

[silver2row]

Hey Everyone,

Today, I tried to make a six sided polygon on the Sketch side of things. I tried via these commands: https://help.alibre.com/articles/#!...gures-polygons-creating-and-deleting-polygons

I figured it would be easy to set the polygon via circle but for some reason, Alibre Atom3D is not allowing me to set up the polygon from the polygon option.

P.S. Is there something I am missing? I mean...I tried before making the circle. I tried after making the circle. I tried just using the option to make the polygon by itself too.

Scratch whatever I said! I got it! "I got it..."

So, it did not do exactly what was expected. I made the six sided polygon with the chamfers. The interior threading is probably more in depth than I currently understand. Please view the photo.

P.S. Oh! The photo:

You can produce an internal thread in a similar way that you did the external thread.
Info is on Harolds crib sheet which you used before.

Crib Sheet and Data for Basic Thread Form to Create Helical Threads - History

Assuming you produce the thread using a helical cut the main difference is the root of the thread is Pitch/8 (instead of Pitch/4) so the thread will be slightly deeper.

Right and A-Okay, I figured this much. I need to not chamfer the nut probably or at least make a less-of-an-impact on the chamfer. Or...no chamfer at all will do too.

If you study a nut carefully, you'll see it doesn't have conventional chamfers. The file herewith shows an approach which approximates to a realistic nut. The method used in the modelling should be fairly clear.
