Problem with Coil.

[Anonymous]

I try to perform a tapered thread profile by using the coil option,
I defined the pitch, taper and revolution.
In this particular case my pitch has the same width than the insert I am using to remove material and I got the following error.
"Edit coilt feature failed, Modeling failure in ASM".

The only way I found to solve this problem is to change the pitch in the fourth decimal (0.0001), so I am cheating the software to perform my part, but I think AutoDesk should have a technical solution for this problem.

I need to perform a coil but having the insert widder than the pitch

Your help will be highly appreciate than otherwise we will have to change to a different 3D modeling software.

We know that Siemens NX can perform a thread in this way.

Thanks and Regards,

I'm kind of surprised that your manufacturing process can work out to that many decimal places - sounds like a really expensive process. When you change CAD software don't change to SolidWorks or you will get the same self-intersecting body error.

Thanks for the comment.

Any way we would like to keep working with Inventor and not changing to another software, if someone knows how to perform the thread in this way with inventor please help us. Thanks,

>I need to perform a coil but having the insert widder than the pitch...

I just tried Pro/E and it worked there (as long as I didn't make the section wider than the pitch).

Can you post the part, zipped?

You can think about splitting the coiling section into parts so that
single coils are not intersecting, as in attachment.

It definitely works.

Hi! Currently it is a limitation in Inventor. Any sweep or coil cannot be self-intersecting. We are aware of this limitation. But, like JD said, having it touching itself might look OK but could prove to be problematic on manufacturing.
Thanks!

Thank you very much for your help.

We were trying to simulate the threading operation of the CNC lathe with the Inventor.

Since you are already aware of this problem we will have a solution in the upcomming version.

Anyway thank you very much for the help.
