How do I scale up drawings?

[wibblywobbly]

I see lots of plans for tanks, guns etc on the web, especially the Bluepring site, but how do I print these off so that I have 1/16 scale drawings to work from?

That one is for resizing photo's. I am looking at blueprints that appear on a web page. I want to be able to print them in 1/16 scale so that I can get the measurements for scratch building models. There must be a way to do it...but I haven't got a clue what it is!

You need a Photo Editor that will allow you to work in centimeters or inches(I'll use inches since I'm American)

1. Take the 3 View like in Pic #1.



2. Trim the image so only one view is present like in Pic #2(I just use MSPaint for this, just seems easier for me)



3. Find out a certain measurement of the full size tank. Wikipedia is great for finding measurements. Width is almost always the easiest to use, but depending on which veiw it is you may have to use length or height.

4. Do some math. Since I'm using inches, I'd take my tanks width(12ft) times it by 12(12 inches in 1ft) This will give me the real tanks measurement in inches, now I divide this by 16 to get my scale with of 9.0 inches.

5. Now in your Photo Editor(In my case Photoshop CS3) take the trimmed image and go an image resize like in Pic #3. If it has an option for contraining proportions, make sure its on, if not you have to do the math for the other dimension(in this case Length).



6. Resize it to the scale size(In this case 9 inches). Pic #4 is the result. Then simply have to do the same thing for each view you want.



Then print it out or whatever you need to do.

Sorry, I don't know why it didn't make those smaller.

As an old git and not very computer literate, forgive me if I sound a bit of a twonk. Do you know the size of the plans you want to upscale to 1:16th? If they're 1:35 you enlarge 218%. If they're 1:48th,enlarge 300% and if they're 1:72nd you enlarge the piccies 450%

I'm hoping you have windows vista with the zoom facility on the bottom right corner of your screen? If so click on custom and away you go to whatever size you want. You may have to adjust the print size on your printer as well though depending on the printer. Failing that, bugger it, print off as normal and "borrow" a copier at work and re size there (just say I gave you permission).

If this is all a load of old b-----ks, just put it down to my age and my propensity for drinking cider till I fall down.

Barkingsquirrel, where abouts in Tampa are you?

[wibblywobbly]

Abo...take my advice and stick to the scrumpy, it makes the paint jobs look so much better. 

Barking Squirrel..That sounds like I wanted to know. I will have to see if my editors do the resizing bit. 

Thanks Guys!

Scaling up by percentages works very well if you know the scale, always do it this way if you can. However most of the blueprints/3 views available on alot of sites do not indicate a scale. Thats when my method of known measurements and math comes in.

Printers will print out at whatever size you tell them too. If you did what I said and printed it out, it would print the image on to multiple sheets of paper, usually with a small bit around the edge blank so they can be fitted together to make one image from all the sheets. IIRC, the M1A1 ends up being about 9 sheets(3x3). Simply glue/tape. Its always better to print it out because 1) not all monitors display the same image the same way, so it could easily be off and 2) you don't need to haul a computer to wherever you're working.

If your editor won't do it WibblyWobbly, let me know and I'll do it for you. I've got alot of time on my hands since I got laid off.

Abo I'm just a little bit north of Tampa in a small town called Odessa.

Wibbly, good idea, can't beat a few pints of scrumpy. I can actually speak in tongues after a skinfull apparently.

Barkingsquirrel, isn't that just up in Pasco County? Never been that far north I'm afraid, I visit a mate who lives in Lutz every now and again, don't think thats too far away is it?

[BarkingSquirrel]

Yeah its in Pasco, but let me put it this way: If I threw a rock, I could hit Hillsborough with it Father north than Lutz Lake Fern Road, but farther South than S.R. 54. Thats about as detailed as I'm willing to get
