Working with Nets and Terminals in Q3D Extractor
A net is a collection of touching conductor objects separated by non-conducting materials or by the background material. A terminal can be a source or a sink.
Nets and Terminals can be modified using the Q3D Extractor > Nets submenu.
Nets can be assigned only to conductive materials. If you want to include a drawn/imported object as part of a net, you must assign it a conducting material.
Assigning Nets and Terminals
Nets can be assigned manually or automatically.
Terminals can be assigned from a list.
