How to generate Arc toolpath on the top surface of an object

[belalhmedan90]

Hi, thanks for your excellent work,

I have an arc shaped CAD file, and I was wondering how can I use this library (best suited options) to generate an arc-shaped toolpath with consistent orientation on the top center of the Arc, can you please guide me or refer to tutorial? thanks in advance.

as this is not really an issue with the package itself, but rather a question, please feel free to close it whenever you like.

You should be able to use the plane slice raster planner to do this, specifying the origin generator as a fixed point on the mesh (or centroid maybe) and the direction generator as a fixed vector pointing along the length of the arc. The caveat is that the plane slice planner has some issues, which are being addressed in #350. I would also consider using the NormalsFromMeshFaces mesh modifier in your pipeline to make sure that vertex normals are generated correctly. There is also a CylinderFit mesh modifier that can fit a cylinder model to your mesh; then you can plan on the fitted cylinder model, which might produce better results.

Can you post what tool path configuration you used to make the image above?
Also, if you can upload your mesh in a comment, I can experiment with some planning configurations that might work and post the results
