How to create smooth (non-faceted) curved surfaces in F360?

[karl]

When I export a .3mf of a model with curved surfaces (like a cylinder) from F360 and import it into a slicer for 3D printing, it's always faceted, even though it appears smooth in F360.  Is this a .3mf issue?  Is there a way to increase the number of segments/facets F360 divides curves into?  Does F360 have any NURBS functionality?  Thanks,

Basically it's the 3d printing industry - standard - to convert curved faces in Fusion to straight triangles in STL.

Send your files to a router that cuts curves, (Gcode - G02 G03) will be perfect.

Might help....

Hi,

the faceting can be controlled (limited)

If you use the Prusa Slicer, you can also slice step files.
But how fine the segmentation is depends on the slicer itself.

-fusion is a brep/nurbs modeler.

-geometry in a .3mf file is represented as a mesh (not nurbs).

you lose the nurbs data when you export to a .3mf file.  the export dialog does allow control of the density of the resulting mesh.
