Hi All,  
I am watching the reverse engineering webinar and it is very informative. The instructor may have said in the video what app he used to take the side view photos used, but I missed it. Can anyone tell me what is used to get the photos and add the dimensioning guide square that the instructor uses in this video? I can take a photo and add a square but it seems like there has to be a way to proportion the square to object in the picture. Thanks in advance. Love the App.

Hello,

It was a piece in the environment when the photo was taken. What was known is the cube has a 10 x 10 x 10 mm dimension from each view. It was a reference for scaling the picture to the exact size.  
Is this what you were interested in?

It is indeed. Thank you. I couldn’t tell in the video if it was added after the picture or included when the picture was taken. Thanks for the response.
