Hi guys,
So I know that a scale is a portion of the object as seen in real life, like 1/35 would be what is divided as long as you know the real life measurements, correct?
How does this translate into uploading and scaling a photo into Sketch Up or CAD? I've attempted it with SU today and just got confused. Initially, I tried to set up the scale as 0.35, but that was too small once I looked at the measurements (or dead on, I guess if it was actually scaled down to 1/35 scale...)
I guess a translation or equivalence would be nice in how to work this out in SU for my photos.
Thanks guys!

Hi. If you take the real life measurement and multiply by 0.028 you will have the 1/35 scale equivalent.

I always use a big DINA3 page (a desk pad is ideal for that) , so i can draw it 1:1 in 1/35 scale.
No need of computers for that :-)
Back to basics! LOL

Brandi,
I have a technique I use in AutoCAD to scale up drawn plans, but before I PM it to you, what CAD are you using and how familiar are you with it? I gave up on ACAD's traditional ratio-based scales for printing & such ages ago...
By the way, you do know that correct scaling from a photo is almost impossible? Lens distortion, paralax etc mean that even a good "side-on" shot can only be approximated because if you get one big sized up to scale, other bits won't fit. (I do this a lot at work...)

Hey guys,
Thanks so much for all the quick replies. Tom, good point about the photos, so approximate is about as close as I can get, huh? Also, not very experienced with CAD yet, but hopefully will be soon when fall semester starts as I am going into architecture.
Claude, I didn't think of that and you make a stellar point. Back to basics it is. I can do rough hand drafting, so I guess I'll be heading in that direction.
Johan, Damian, thank you for the help!
You guys are so awesome!
Hope everyone had a good week!

A scale is expressed as a fraction. Thus, 1/35th scale is one divided by thirty-five, and if you actually do the division, you will get the digital equivalent, in this case, .02857143. You can round that up to .029 or round it down to .028, as you wish. Any full size measurement is then multiplied by .028 to get the scale equivalent.

I have a question to clarify for a building i'm trying to construct... what is the equation i use? say one floor is roughly ten feet (120 inches)... how do i get a two story building, with an intact erected roof, to be 1/35 scale?
thanks for any help

Um ... you divide the size of the real thing (in your measurement unit of choice) by 35. So ten feet scales down to 0.286 feet or 3.43 inches. How tall the building will be overall depends on the design of the roof, so it's impossible to say.
