51// Class: SoBevelAction
52//
53// For beveling nodes in a scene graph or a path list. This action traverses
54// a scene graph or a path list, and constructs another scene-graph where the
55// shapes are beveled.
56// The beveling properties can be set directly in this action as default
57// behaviour, or inserted in the scene-graph using a SoBevelProperties node.
58// Specific vertices and edges can be beveled / not beveled using the
59// SoEdgeFlag an SoVertexFlag nodes.
