Wie man Linienobjekte erstellt

Als einfaches Beipiel finden Sie hier den Code, wie man eine Linie erstellt, gefolgt von einem Button-Event, das eine Lage hinzufügt und eine Methode nutzt, um eine neue Linien auf dieser Lage zu erstellen.

Am Ende steht eine Methode, die die Werkzeugdefinition im PCB-Investigator überprüft und ein neues Werkzeug erstellt, falls das gesuchte nicht existiert.

Hier finden Sie den Beispielcode in C# und VB:
