После использования Line и Polyline, независимо от того, что я выбираю (круг и т. д.), он всегда ссылается на последнюю ⇐ C#

[Anonymous]

Я создаю 2D-приложение CAD на C# для изучения кодирования. Но я остановился на простых вещах. Я много пробовал, но так и не понял. Я просто хотел, чтобы после использования линии или полилинии моя текущая позиция была сброшена, но это не так.
Если это возможно, я могу отправить сюда весь проект.
Вот мой код:< /p>
