Threads on a oval

[Anonymous]

Can Fusion 360 Model threads on a oval face? i have tried a couple times and have not found a solution. 

Thanks

Not with the thread tool of course.  Do you mean something like the attached?

Thanks. That is what i was looking for. I am in the process of replicating a piece from my daughters doll toy.

That looks like it was turned round with green wood, and then it went oval once the wood dried out.  Seen it many times in older/antique handmade furniture.

Just out of curiosity, are the threads supposed to be decorative? Because I can't see them being functional. Decorative threads might be easier to model as they won't have to follow precise specifications.

Once I looked at your pics and thought about how that cold have come to be, I did a head smack and thought of another way.

Make a reagular round cylinder, use thread tool to make your threads, and do a non-linear scale to make it oval. (just like what happened to your original part when the wood dried out.)

example attached.

Thanks for the input. Here is where the peg \ part goes. The threads are functional.

Then they cannot really be oval, or the oval that's on the objet now was not intended to be there or is really only very slight.

As @laughingcreek said, the originals were made while the wood was green.  If I were going to replicate the part, I'd model the threads on a round tenon and the rest oval to match the broken part.  I think a spokeshave and drawknife would be the fastest and easiest way to make the part
