Round surface node

Generates round fillets of a specified radius between two surfaces.

The Round operation generates round fillets of a specified radius between two surfaces. It can also be used to round closed surfaces, as it will generate spherical patches to fill in the corners.

Each surface in group one is compared with each surface in group 2. If they come within the specified radius of each other, a rounded fillet is generated between them. The direction of the fillet is determined by the normal of the surfaces, modified by the Flip Fillet Direction toggles. For best results, ensure that the normals of all surfaces face outward from the center of the object being rounded. Note that self-fillets are not performed, even if a surface is in both group one and two.

Parameters

Round group 1	Subset of NURBS and Bezier surfaces
Round group 2	Subset of NURBS and Bezier surfaces
3D Tolerance	World space precision of fillet
2D Tolerance	Domain space precision of fillet
Marching Steps	Number of steps for tracing each profile span
Radius	Radius of the fillet
Span Density	Density to build fillet. Higher densities will provide a more accurate rounded fillet at the expense of more geometry. The actual number of isoparms in the fillet is a function of this, the radius, and the length of the fillet.
Flip Left Fillet Direction	Logically flip normals of left surfaces
Flip Right Fillet Direction	Logically flip normals of right surfaces
Trim Primitives	Try to cut surfaces back to the fillet
Cusp Angle	Angle at which a sharp corner is made
