Hi

1. How do i get the thread in part-1 thread .ipt to have a greater height. I changed the Coil feature height from 80mm to 90mm but it had no effect on part-1 Thread .ipt  ?

2. How do i add the thread to Part-2 Thread .ipt so that when part-1 thread and part-2 thead are assembled that they fit correctly?

Regards

Richard

Not sure why you have both Rev and Coil on your Part-1 and why you have another RevolutionSrf and Coil suppress. Just use the Coil command with the "Cut" function to cut your thread profile for the Female threads in Part-1.

Use the Coil command with the "add" function to add the Male thread to the exterior of Part-2. Not sure what thread you are "cutting" but you may want to access the "Machinist's Handbook" to set up your Major and Minor diameters along with all tolerances.

Your Coil2 only needs a single tooth profile for the cut. All threads only consist of a single groove.

Thank you

It was a continuation of this thread....

If possible could an example be posted of the 2 parts with threads which match

I usually always use the thread appearance but for these parts would like to use a natural looking thread

Thanks

It would seem that this request is not worth an example from experienced Inventor users so i will not bother waiting for 1.

Thanks

Let me just drop everything at work and tell customers to take a flying leap while I volunteer my time to help out someone who doesn't understand the basics about threads at their drop of the hat request be cause they would rather look at real thread rather than the BMP. Not that they need read modeled thread for 3D printing but only for the visual appearance.

Thanks for your time. On every bolt i use i place an appearance thread not a cut thread as you have posted.I just use appearance threads on bolts

The request was for the following

In part-1 attached in the first post it has already the real thread required. I wanted a real thread on Part-2 which then fits correctly to part-1 when assembled. 

This was requested by someone from me which clearly i do not know how to do as i use thread appearance. It would be good to know how to model these threads for future use if required.I just dont have the experience on these real threads as i use appearance threads for bolts....

Sorry i asked and lets forget about the request and yes i do appreciate the generous help of volunteers. i gave my appreciation for the help on part-1..

I don`t know whether people are busy at work or just dont want to reply......

Have a great day

Look at Sketch4 in the Coil1 Feature. All threads whether they are External on a Bolt or Internal in a Hole all start the same with a sketch profile of the thread. Sketch5 and Sketch6 just set up the proper diameter (don't worry about them).

All threads consist of a single groove that is cut into the material and a pitch (number of grooves per inch or mm). You should invest in a copy of the Machinist Handbook. This will explain in detail the thread profile, what size hole is required for each size of thread.

The majority of the EE members and other contributors on this forum are employed in private industry and are not ADSK employees. Most don't have the time to spend on non-software issues such as threads and thread clearance tolerances.

Good link on Threads along with the attachment.
