Progressive threads


Recommended Posts

Hi there,

I need to draw a progressive tapered thread.

I use Mechanical desktop 6.

 

To be more precise, I have to draw a screw 2.25 inch long starting from nothing up to 1.125 in diameter. The thread need to start fine at the tip and finish coarser at the end, around .2 pitch.

 

What option could I use to draw this.

 

Thanks in advance

Sorry for the delay, damn final exam.

 

Yes it have helix, or I think so. Their a 3D helical path that I already use but the thread are the same all the way.

 

I want to modify the thread on the way up.

 

Ale
