Hi Burman

Thank you very much for your effort in making the video. Appreciate it very much!

The thing is: in the final result (front view), the building has 'the same height' from left to right, while for it to be seen as 'correct in perspective' the leftmost part should be somewhat shorter than the right one. I tried to do it the same way as your video, followed by flow-deform it from a rectangle to a trapezoid. But it gave me an unexpected result (and took quite a while to process).

So I decided to simulate it with a simple circle, and here's what I got.



1. Choose the circle
2. Apply Deform > Flow
3. Pick the upper right corner of the square as 'base curve'
4. Pick the upper right corner of the trapezoid as 'matching end'

I don't use deform quite often so surely I'm the one who's mistaken.
