No it dosen't!

You have to take some mesurement of at least 4 points (or more for better accuract) that are for example the windows in the existing building or a bench in the street ect. you need to know their sizes/height. Also you need to know the spec of the camera is it 28mm 35mm,.... and it`s position in relation with the objects that you've mesured(theoreticaly you don't need it but you will get much much better results.) and then put all that info in to your scene.

Max will generate then the camera.

Search for some tutorials at google

to be honest i do it by eye simply because the camera match utility in i found in max sucked big time

most projects i either shoot the plates myself or brief the person doing a shot to make notes about exactly where they were

 

then when push comes to shoeve you can always try this

yes, as long as you have known reference points and camera info from your photograph max can generate a scene camera for you. this isn't (and usually isnt) available. then you have to do things by eye.

 

personally, i always eye things up.
