How do I go about enlarging a drawing of a ship to 1/35 scale?

What is the scale of the plan?

Cheers,

Joe,

No scale just a drawing.

Hi Sam,

I have a scale conversion chart and it is set up to covert
from scale to scale so that the % in reduction or enlargement can be calculated....sorry.

Cheers,
Joe

Joe,

Plans are in PDF format & are in 1/72 scale. I am wanting to enlarge them to 1/35 & use adobe poster to print.

Hi Sam,

You must enlarge them 205.11% to get them in 1:35 scale.

Google Frank Krenshaws' Scale calc.
It takes all the phew out of the Fu
for those of us that are mathematically challenged!

you would put the input units as 72, output units as 35 & it gives a 205.7% enlargement...

IT does far more than that though

What's the boat, btw?

People.

Changing scales isn't rocket science. Scales are nothing but fractions and this is grade 3 math.

scale of first drawing = 1/72

scale you want is 1/35

measure length on 1st drawing and multiply by 72 to get the length on the real vehicle. Then divide that real vehicle dimension by 35 to get the dimension in 1/35.

so A times 72/35 = B

The exact same ratio is used to scale up or down one drawing to a different scale. I.e. Old scale / new scale

in this case 72/35 = 2.05714 (205.714%)

To scale from 32nd to 48th. Old over new 32/48 = .6666667 (66.67%)

This is really basic fractions. I'm not trying to dump on anyone, but just think it through. It isn't sanskrit or calculus or latin or quantum physics, it's just fractions.
