Я пытаюсь создать модель, используя GeometryInfo.Я просто делаю плоскую модель и прикрепляю ее к ее отражению по оси Y для симметрии.Но при запуске следующий код показывает только половину модели, которую я запрограммировал (он показывает только сторону слева от оси Y).Что я делаю не так?
Программа запускается из класса Stage.Буду признателен за любые предложения.
