Bad Spun Profile (Bug?)

bristow — Thu, 24 Oct 2024 16:14:28 GMT

Attached is a stripped down model from one of our customers. I removed as many features as possible, with the problem still persisting. The issue is the spun profile generated when setting up a turning operation in the manufacturing setting produces unwanted shapes and drastically alters/ removes features. So far, I have used a couple workarounds to avoid this:

Increasing the tolerance of the spun profile works to a point, but the attached project needs about 0.01 and still isn't 100% correct
creating my own spun profile and turning off spun profile in the set-up

Each of these solutions comes with drawbacks, most of which being a headache, time lost and confusion with on floor operator/programmers. Where this really affects us is on our large VTL turn mills with live tooling; being able to switch between turning/milling of asymmetric parts without having to juggle models.

If this is an issue on my end, please let me know, otherwise I would like to report this bug and submit this project to help. Thank you, I appreciate your time and help in the matter.

This is what I'm seeing in current Insider build, which is what you would see in a few weeks or so. Is that what you expect to be seeing?

It is tough to see, but does the spun profile encompass the model? If so, then yes, that is what I would be looking for in the spun profile. If it is fixed then it will be pushed out in the next update?

In Fusion's preferences there is an option to use the old spun profile feature, just uncheck this option.

Also does the actual part have cutouts in it or is it solid like the part youm shared? If it's solid you don't need to use spun profile in the setup at all.

This is using the old spun profile.

As mentioned above, I have workarounds figured out, but I wanted to bring the bug to the attention of those who could fix it.
