PS perspective grids

anal from analytical I hope?

ok. this is my last post here as I seem to be wasting my time.

when you take a look at images A and B on that tutorial, you will notice that the squares in A have become rectangles in B.
proof: the height of the first row in B is larger than in A while, due to foreshortening, it should be smaller (less).

To get squares in perspective you have one and only one exact relation between height and width. You can not get this by simply making that square grid shorter the way you fancy.

This tutorial is not serving its purpose. And giving half-hearted solutions is not the purpose of QT&T forum.

Yes, I certainly do see your point, and obviously you're correct. I should qualify the purpose of the grid. As an illustrator, not an engineer or draftsman, I occasionally need to illustrate an object that has the appearance of depth. In photoshop, which is for all intents and purposes a 2d app, I had a need for a guide to be used primarily for shading and for angles. I came up with this, it works for me and I'm a damn good illustrator. I was sharing that and it's valid. It's not a CAD tool. It's a guide. However, if you're so offended by it, by all means, I'll remove it. No skin of of my teeth
