Unable to CAM a Quad Mesh

[chrisjmulhall]

Good morning,

I have a quad mesh .obj that I am trying to generate a 3axis milling toolpath from, however I am encountering various problems.

1) I cannot select the body or model as a target for the adaptive clear operation

2) Quad-Mesh to T-Spline does not solve this

I have attached the file below.

How can I generate a toolpath for this model?

For some reason I cannot upload to the forum directly. Whenever I click "post" the file uploads, then the screen refreshes back to the same screen.

I have uploaded the file to google drive instead: https://drive.google.com/open?id=1d0HogZDvymLX87fGhm4hojjXfF7jWAAo

Hi Chris,

i think you have to insert this into a session, then you should be able to wrap some stock around it and machine it.

Have you been successful with the file I provided?

For file types blocked by the forum the easy workaround is to ZIP the file and upload. As for the quad mesh, I seem to remember the CAM only sees triangulated meshes, there is a option to triangulate the mesh on import in preferences.

Hi Seth,

I have managed to resolve this but ended up taking a slightly different route.

1) I saved the quad mesh as a triangulated .stl instead of a quad-mesh .obj

2) I used MeshMixer to reduce the poly count by 90% which did not affect geometry.

3) I am now able to machine the part in Fusion360 normally.

Extra steps:

I completed a simulation of the toolpath and saved the resultant shape as a new .stl. This new model is the nearly the exact mould shape I needed, which I was not able to model before. I imported the machined model back into MeshMixer to add fillets and re-ran the CAM setup.

Thank you to everyone for their suggestions.
