I was thinking about the flat view of the door and it suddenly clicked, because its on a hinge its rotation around it describes a cylinder, If i know the with of the door and it is in front of me in one point perspective Then i can figure out by using the center line of the box the size of the box this cylinder would fit in. If i divide the circular top or bottom of the cylinder in half going trough the center point it will give me the vanishing point for that door plane, then I can thicken the slice up a little to make a door box. First one I did through the center of the rectangle which gave me a thin revolving door. The second one to get the rotation of the door outwards I drew the box that was to be the size of the door then doubled it to make the hinge point for the door on the center line. Im sorry if this is very obvious to everyone, but this is the first time on this course i've figured something out on my own. And I think I said out loud "my god, its boxes!" :)

I am overthinking this and all in all I probably should have done the current assignment instead but I felt the need to do it. The passing from one side of the square to the other looked very wrong to me and I tried to fix it and I did not really succeed. The first fix was making the perspective wrong which in my opinion makes it look more right but I'm not satisfied with that without reason. The second try I thought a circle instead of a square might fix it but it ended up doing virtually nothing. At this point I am more or less ready to accept that I can just treat this small issue as a case by case and move on, it was an interesting experiment at the end of the day.

This video gives important info about the flap directions that I did not read well enough...☺️ Like Marshall said in his critique: let's not wear out our helpers.

Door rotation. Tried the lesson exercise on my own.

This solves a lot of my problems when drawing buildings

So just to be sure. Can I decide, when adding a “door-flap”, if I pick the left or right? And based on looks I decide as an artist which is valid? For a role(?) do I only add a vp to the top or down but does the other vp stay put? great lessons! You increased my level immens!
