Filleting meshes

Use this feature to create fillets and chamfers on hard edges of meshes by identifying sharp edges and applying filleting operations.

API functions: algo.identifySharpEdges and algo.filletMesh These functions allow to create fillets and chamfers on hard edges on meshes. First, one must use the algo.identifySharpEdges to mark the edges on the

occurrences

that are to be filleted. This function allows to mark as "sharp" the edges whose angles are between

minSharpAngle

and

maxSharpAngle

. They can be filtered by their

convexity

and using

onlyExplicitSharp

one can choose to also use the normals of the mesh for the flagging.

Note

The viewer will not highlight the marked edges nor the ideal chamfers.

Once the edges are marked, the algo.filletMesh can be used. The

value

of the filleting depends on the

FilletingMode

As shown, all these parameters are linked to the angle of the edge. For instance for the same

width

a fillet on a sharp edge will have more

distance

than a fillet on a flatter edge. Using the parameters

subdivisionNb

and

createFlatChamfer

allows to create more or less rounded fillets and to create chamfers without normal interpolation.
