Помогите построить по трём поперечникам поверхность с помощью функций VBA.
Обычными командами AutoCAD эта поверхность строится функцией Loft или ПОСЕЧЕНИЯМ: выделяются подряд 3 идущие полилинии например и они автоматически соединяются поверхностью, которая в свойствах называется ПОВЕРХНОСТЬ (по сечениям).
Как такую поверхность построить методами VBA?
Поискал похожие методы и не нашёл. Может плохо искал?

Спасибо hwd!
Применил метод для Polyface Mesh
Но почему не все треугольники поверхности отображаются на экране?
