If by fully cut you mean to model them fully from taper to taper in the part I believe you will need to make the threaded portion a unique part, longer than the space between the tapers, and then combine it with the part containing the tapers. As it sits the thread tool is working with only the distance between the tapers so it ends the thread at the end of that distance.

For future reference you are more likely to get rapid response if you Attach *.f3d file rather than zip or *.f3z

Do not add Chamfers/Fillets until AFTER threading.

1. Initially do thread feature as Cosmetic.

2. Add Chamfers/Fillets.

3. Edit the Thread Feature and change to Modeled.

BTW - it is usually best to add Chamfers/Fillets as placed features rather than in the sketch.

Hello

Thank you for the support

What I don't understand is why it's not possible to select an edge or face to define the beginning or end of the thread if necessary.

Thanks for the attached file, this really seems like the best workaround to bridge this missing feature in Fusion.

In my experience, when creating a "Stages of Design for Manufacturing" Model, the most efficient and clear method is to define the edges and fillets in the sketch.

Thanks again

@Christoph_360

That has not been my experience.

I worked as a machinist out on the shop floor and then taught Design for Manufacturability for 30 years.

But whatever works for you.

In any case, in Fusion it is usually best to use Placed Chamfer/Fillets rather than sketch chamfer/fillets.

Keep the sketches simple.
