Мобильная версияПотому что я пытаюсь перегрузить конструктор и всегда терплю неудачу.
Когда я запускаю свой код, я всегда получаю это исключение.
Выброшено Autodesk.AutoCAD.BoundaryRepresentation.Exception.
< /blockquote>
Я использую .NET Framework v4.8 в Visual Studio 2022.
Кто-нибудь может мне это объяснить?
Это мой код:
