[QUOTE=You're making it too difficult. Print the photo, draw the angles with a pencil and a straightedge, and measure the angles with a protractor.[/QUOTE]
I’m an architect and could certainly do it this way but when trying to tweak a fit with an iterative process it seems like there are more efficient options. Every fit video on YoutTube shows digital angles drawn on a photo, just wondering what they are using.
For that matter I suppose I could use AutoCAD, if needed.
