I'm getting "Diameter must be greater than ..." errors on every tool I edit.

I'm experiencing a error I've never seen before.
Every tool that I edit shows the one or both of these errors (see screenshots below) ...

• "Diameter must be greater than the diameter of the tool shaft" or 
• "Diameter must be greater than the reference diameter"

I've had these tools defined in Fusion for over a year and have never seen these errors until yesterday. 
Any idea why this is happening? 
Thanks

Hi

This Is a Bug that has been logged

I'm not sure when a Fix will be available though

Seems Maybe to be an issue with Inch tools, I haven't noticed the problem myself.

You can Re-enter the value and it should correct but that's quite annoying

Do we know if this bug is affecting toolpaths? I ran a 6061 part tonight, nothing too challenging. The toolpath looked good in the simulation. When I ran the part the 1/2" end mill snapped.

I wouldn't think so, Its possible that part lifted in the Vice, Seems to be a bit heavy of a cut, without seeing the File its hard to comment.

Its pretty hard to break 1/2" carbide endmill in ali

@a.laasW8M6T Ahhh yes! After stopping the machine I noticed that the part was slightly tilted in the vice, but the Mitee Bite Talons kept if from getting ripped out. I was thinking the crash and snap of the end mill caused that to happen. But it makes sense that it was the other way around.

Looking at the part now, I can see how the lift caused the cutter to dig deeper into the material and snap the end mill. Looking at my toolpath, I forgot to reduce my stepover. It was cutting a 3/4" depth at 6,000 RPM and I left the stepover at 50%. 🤦🏻‍

Would you be able to share your Fusion file here?

Sure @seth.madore, here's a link to the file: https://a360.co/4aVkcv7.
It was too big to attach it to the post.
