Hi All,
Have been following this thread with interest.
We appear to have two methods of getting drawings from one size to another.
one - take it to a copy shop (or do your own thing with scanning and reprinting)
two - measure from original and redraw at the required scale.
ok - the first requires a bit of simple maths to get the required scale conversion, and a bit of faith in modern technology to actually do what you want.
ok - the second - can be done basically two ways - shall we say method A is where one measures the original, converts it (in head, on paper, or using calculator), Murphies favourite as the opportunities for him are endless.
method B for the thinking person. Use two scale rules - scale the original with appropriate scale rule. Then use the scale rule of the scale you want and draw. Hey presto, no calculations, read from first scale and draw from matching position on new scale. Don't have the appropriate scale? then make one, very simple.
Redrawing from paper plans into a computer, once again use appropriate scale for paper drawing, draw into computer -BUT AT A SCALE OF 1:1 - FULL SIZE - (ie if the ship you wish to model is 80 feet long, then draw in CAD a ship 80 feet long. When done, print off at what scale you want your model to be - that way any minor errors, inaccuracies or such are scaled down and probably cannot be noticed, and if adding detail from photo reference you are working in real units, not trying to convert in your head etc.
Also, if you or your fellow modellers then want to make a model of a different size, simply reprint at the new scale, you know it has to be right.
Anyway, that's my two bobs worth, and how I was taught to do things by wiser men than me, back in the sixties of the last century.
cheers
