Fusions Cam stopped recognizing my mesh model

[FacebookGroupMember]

Hey folks thanks for the add 👋. I’ve got a mystery and maybe y’all can help me figure this out -
I was half way through a project when Fusions Cam stopped recognizing my mesh model. I cut one side just fine, came back the next day to do the second side and I started getting a Zclearance error. If I regenerate the paths I used the day before, they ignore the mesh and cut / face the stock down to the set bottom height. Also the “shadow” of the paths I had programmed have now moved away from the stock. Moving the model in Cad will correct the Zclearance warning, but it no longer recognizes the mesh model.

I was just doing this as a learning project / making something fun for myself (it was supposed to be a lamp base) so I’m not out too much more than my time but, man what a bummer. Can anyone shed some light on this one? My only guess is that fusion updated between operations, I see there’s new buttons in cam that weren’t there last time, but I wasn’t able to find anything about meshes that might have changed in the updates.

double-check your setup.

Daniel Lyall I have, and I’ve tried remaking the part from scratch, and without the solid body. It won’t seem to grab the mesh

can you post a link to the model

you need to make it downloadable

Daniel Lyall I am a lowly personal use non paid subscriber 🤦‍♂️ is there a way to share it without the subscription?

I forgot about that, it is a pain but there is a reason for it. You have to do it from your hub I am just doing a video showing how to do it now.

Thanks man! I’ll get that done when I’m finished up for the day.

There is a known bug that is plaguing customers that work with STL files. We are investigating it and it has a relatively high priority

To add some more information to anyone else who is having this issue.


A current work around to the issue of the toolpaths being in the wrong location for meshes.

You have your main document lets call this "main doc" you want the mesh in here to machine.

Now make a new document, insert the mesh into here and DO NOT MOVE IT, just import. Save this as "Mesh1"

Now insert as a derive "Mesh1" into "Main doc"

You should now be able to move the mesh around to your hearts content and still reference it correctly in the MFG environment. 

We will of course try to get a fix out but this may at least keep you working.

Autodesk Community awesome thank you! I’m no expert at this but it was working, and then all of a sudden did not. I wanted it to be a bug, but it was just as likely that I broke it 😂

I'm having the same problem. I'm in the middle of milling a 8 foot multi-layered part from foam and CAM is no longer recognizing my meshes as surfaces. This is how I've worked for years; parts that I have already completed no longer work when the tool paths are regenerated. I'm stuck in the middle of a really big job. 

[JasonJFerguson]

Quick follow-up, I tried the derive method, it did not work. The CAM path still went straight through the mesh and milled the entire stock. I can send the file if that would help.

[JasonJFerguson]

Thank you Seth! I am stuck in the middl of an eight foot 3D mill job and I can't move forward. The CAM paths are passing right through my mesh.

That would be helpful. Thank you.

Thank you Jeff. I haven't done this before, what's the best way to share a file with you?

[jeff.pek]

The most common way is to export a model (as .f3d or .f3z), and share it here as an attachment.
