Title: scaling plans
Post by: class37 on October 24, 2009, 09:53:05 pm
Hi all,
can I just check that I have something right ?
I have read loads of the posts on this, and I think I have got it right, but just want to check before I start copying.
I've just received a set of ship plans at 1/100 scale, and I want to photcopy them to 1/72.
am I right in thinking that to get the new setting I divide the old scale [100] by the new scale [72] to get a ratio of 1.38 recuring.
so I copy the plans at 138%, and this should result in 1/72 scale plans.
then take a known dimension from the data sheet, measure on the original 1/100 scale plan, and do the same on the 1/72 scale plan, and the resulting measurements should be at 1/100 and 1/72 of the original real dimension.
many thanks in advance
cheers
alan
