I’m interested in 3D printing but haven’t gotten one yet. I may when my sons get a bit older if one or both of them take an interest in it.

You know, I taught AutoCAD for 5 years and I should have remembered that door widths are a good universal standard for measuring! Thanks! (Also, do you do any 3D printer stuff?)

Extrapolate the dimensions. If the building still stands, measure the door, then extrapolate the rest of the dimensions from a photo. If the building doesn’t still exist, you can approximate it by assuming the door is 7 feet tall. In a really simple example, let’s say you have a 2-story building where the door is exactly 1/3 the height of the rest of the building. In that case, if we assume a 7-foot door, the building is 21 feet tall.

Similarly, you can extrapolate the width of the door from the height, then get the width of the building. Just measure everything relative to that one known measurement. Make sense?

I mean, I know if I have a building that is 87 feet wide, the scale model will be 1 foot wide, but how do I do this without actually measuring the actual building using a measuring tape? I am thinking about using Autodesk’s Recap program to take a series of photos that are then stitched together, then Cura created the slices for printing on a printer, lets say a i3 Mega 3D printer? How do I get the final model the correct size without measuring the real buildings in real life?
