Working with Scale-How???

[Wad Cutter]

I have a multi page PDF model. With in it are a couple of pages that I need and not the whole model. The pages are in 1:33 scale. I would like to use these parts on a different model which is 1:87 scale(HO scale). Is there a way to convert the 1:33 to 1:87 and be able to use them? This kind of question hurts my head even thinking about it and I am surprised I was able to type it. Thank you for your help. I am handicapped my a megrim right now adding to the my difficulty

Hello Wadcutter.
I went to Best Paper models Scale Calculator, and input the 1:33 to 1:87 conversion for you.
The answer is to print the pages required at 37.931%.

Should you wish to confirm this figure for yourself, the link to the Scale Calculator is here:

I hope the information assists you in your endeavours, and that they succeed well.

Kind and Respectful Regards Wadcutter, Uyraell.

And to show that this is not magic:
You first go to 1:1 scale by multiplying with 33 (because scale 1/33 means that the model is 1/33th the length of the original), and then you devide by 87 to get the scale 1/87. In short, the factor is

33/87=0.37931=37.931%

And final piece of the puzzle, in order to print at 37.xxx percent, download Foxit PDF reader. The print options have a section where you can specify an arbitrary percentage to print at, to the second decimal place. Adobe only gives you a couple presets.

There's a link to the software in my getting started post:

Beginner's Toolbox - Tools and software to get started with Paper Modeling

And a discussion on how to rescale using it (screenshot shows everything) in this discussion:

Rescaling & Printing PDF Models

[Fishcarver]

In these formulae,

P= Print Scale Required
O (Alphabetic) = Original Scale (eg: 1:25)
D= Desired scale (eg: 1:35)
/= divided by
e = enlarged
r= reduced

TO REDUCE scale:

rP= O/D
= 25/35
= 0.71= 71%

To ENLARGE Scale

e P=D/O
=35/25
=1.4 = 140%

Remember that the LARGER the number after 1:x is, the SMALLER the model is.

1:1 is life-size.

Thanks, Chris for the link to Foxit!! Now I can rescale those pesky .pdfs!

Hope this helps!

Thank you guys for all those great ideas. I think I will be able to pull it off now once I get through the Piper I'll do the hangar next and take some photos and show ya how your help paid off. It won't be for a while. This Piper is really being a tough little girt. The windows are not going in easy. Thank you. wc.

On Foxit reader when you print there is a scale box right under the preview window...highlight it then enter your scale and hit enter amd it will let you put in any scale you want.Very cool!...Rich

Thank you Rich for that tip. I will have to look into that once I get some time. Right now I am going so many different ways it's driving me nuts. That might be the way to go. Do you use it yourself? wc

The scale box is actually a percentage box.
I use Foxit Reader and the percentage box works well to reduce a image to whatever size you need.

The percent can be set to + 0.01 %.

Figuring out the rescale is pretty easy. Getting your printer to put it out (out-put it?) is the hard part. If all else fails, rescale it, save it, and take it to a digital printer!
