Components run outside the drawing boundary: components are not created in the center of the component library chart paper.   (2)  The network table of the created project file can only be partially transferred to the PCB : the netlist was not selected as global when it was generated.   Never use annotate when using a multi-part component that you have created yourself.   02    Common errors in PCBs   (1)  NODE not found reported on network load   • The componen
