Fusion 360 exported models has edgy curves

[Anonymous]

Hello Community,

I am using Fusion 360 for a long time, so i was wondering if i could export my models as .fbx or .obj and then import it into a 3D renderer like Blender cycles or Keyshot to create realistic renders of it. But i see that, whenever i export my model from Fusion 360 all the curves becomes edgy like a polygon with straight lines.

I don't know how to solve this problem, is there anyway to resolve this or is Fusion 360 models just not meant for use with polygon modeling tools ?

Thanks in advance !

Exporting for use in Keyshot, Blender, or other polygon based tools will always requires conversion into a triangulated mesh. There is a plugin for Keyshot, but I am not sure the resolution can be controlled there.

When exporting to .obj and .fbx unfortunately the resolution can not be controlled. The only way to control it is through export as .stl right from within Fusion 360.

Generally triangulated meshes are not easily edited within polygon modelers, so make sure your design has all details needed for rendering such as fillets, chafers etc. before exporting.

In have heard of a  plugin under development that would allow direct import into Blender.

Thanks for replying, but i wanted to know if the curves and fillets in
exported files can remain smooth? When exported they look like low poly
mesh.

The simple answer is NO.

CAD software represents 3D geometry in form of analytic geometry and NURBS surfaces or BRep containing such objects. Those are mathematically precise, resolution free descriptions of geometry.

Polygon modelers or external render engines do not usually accept that form of geometry and as such it has to be converted, usually into a triangulated mesh. Meshes have a finite resolution. IF you set that resolution high enough, tesselation artifacts such as these "edgy curves" will not be visible.
