Dimension.byface surface plane direction to dimension

Hi, which face planes do I need to sort to get this to work. Is it the faces parallel to the view direction or the other ones? Its quite confusing as it spits out dimensions from anything.

Views directions the green arrow and red is what I assumed it would have been.

Broke it down. Tried a placing line above the door and at the views plane. Wont place the dimension for some reason. Frustrating, feel so close!

Maybe its the type of surface I’m getting? don’t know how its cylinder when it should be flat.

This made the dimension. Where it is I’m not sure. @Alban_de_Chasteigner any advice? seems to be a few dimensions floating around the place when I play with view settings that are being deleted from testing different face inputs

Tester script below if anyone want to mess around R23 dynamo. Just need to elevate a door.

hello did you succeed?

I did but by creating lines on the door edge and something to figure out what was the door edge line. Can send on Monday if you want

I’m indeed interested, but I’m also stuck with this quotation thing that I can’t get to work. :smiling_face_with_tear:
