Re-scaling a drawing 1

[datacroft]

As a hobby, I have designed a building structure that, when printed onto card, can be cut out and made into a 3D physical structure. Think of origami.
Now my perceived problem, being a complete novice.
I have created my building drawing in a scale of 1:144, how can I change the scale to say 1:72 or 1:200 whilst maintaining accuracy of the dimensions?

Thanks Johnwm,
I have tried to follow protocol by doing numerous lateral thinking searches before I posted my question but alas to no avail.
Probably because I did not pose my question correctly.
I created my original drawing with a page set up of 1:1 (no scale.
I appreciate that if I had started correctly, I could rescale to my hearts delight.
However, would my reasoning be correct in assuming that my original being 1:144 (1:1)and I wanted to print a 1:200 scale drawing (144 / 200 = .72)I would need to reduce by 72% and if so how?

If you want to change so that a drawing actually at 1:1, but drawn as 1:144 so it looks like 1:200, go to File - Page Setup - Drawing Scale, select custom and type in 144 in. in left box and 200 in. in right hand box
