A weld line is created as an AutoCAD polyline with the corresponding weld data.
Weld lines establish a connection between objects (e.g. beams and plates). These objects contain not only the weld properties but also the logical connection between the connected structural parts.
Weld lines are inserted in the model as individual elements and are represented as thick polylines.
