All Implemented Interfaces:

public class PgTube
extends PgElementSet

Class generates a tube either around a given polygon or around edges of an elementSet. In case of polygons tube is generated e.g. by parallel translating a frame. It requires an existing polygon of class PgPolygon and produces a tube which is a subclass of PgElementSet. In case of element sets tube is generated by using vertex normals.

Note: Currently, the dimension of vertices of tube and of base geometry must be 3.
