A poly beam is a beam sequence (straight beams, curved beams or a combination of the two) created as a sin-gle object. Any section class can be created as poly beam. To create poly beams, a polyline must be created. Any 2D or 3D polyline can be converted to a poly beam. The position of the beam is independent of the coordinate system since the beam position is determined by the position of the polyline. There are two ways to draw a poly beam: • Directly in the model by specifying the points (point by point). The beam is drawn in the X/Y plane of the coordinate system • By selecting a polyline. Any 2D or 3D polyline can be converted into a poly beam. In this case the beam position is independent from the coordinate system since the beam position is determined by the position of the polyline. Additionally, any line or arc can be converted to a beam using the Beam from line tool.
