Many artists out there would find your remarks insulting. They have studied perspective and some still find it hard to do. 3D apps come from perspective drawing and to demean them is a hugh insult. Oh Please! It’s guys like you that helped the government close learning facilities because you do not think we should learn the most fundamental part of art.

This is my first involvement with a forum and I still find statements as yours a shameful way to behave.

‘In 2 point perspective you have 2 VP's a horizon line and that's it’, your words.

Please show us how you measure 2 10ins cubes going off in the distant with one side 34deg, one behind the other with a space of 26ins? If you can do that with 2 VP's and a horizon line I will leave this forum NOW!
