Hi Cenekh great from you and thanks a lot.
well as i said one time i print my drawing( i redraw in Adobe Illustrator) a 2D view and in 1:100 scale. sure i use one scan of the plan to redraw and
make a better simetry cause the simetry of a computer really is much more efficacy than hand drawing.
well i use double face ribbon to glue paper drawing to styrene plate. is so much efficacy this method cause white glue don't work very well(in my opinion) in the plastic and you may need wait the glue dry. in some small cases i use white glue but just in small cases. i prefer double face and i don't use the double face in all drawing. Just in some parts cause is unecessary. Yes i use Macintosh platform.
about your request subject. if you use jpg( i think so many use this method of jpg) you can use it with no problem.
i would like to explain one thing about that.
i use AD. Ilustrator and you use Photshop or any program to manipulate your scan drawings. Ok.
The difference of ADOBE iLUSTRATOR of the Photoshop is the Illustrator works with lines and Photoshop with pixels. so a small file of Illustrator can be rezise with no loss of quality and the print quality of this don't change with resize. in the Photoshop to have a good quality you need a great file to have the same quality of illustrator.
so if you can't acess to illustrator or if you don't know how use the program you can use the jpg files in photoshop and with a medium DPI(about 150) you can have a not so good quality but satisfactory to print your plan an see a good lines of the drawing plan. sure if you have more DPI more the quality you have but more the size of your file. i mean wich wit a drawing of 2 meters is so much heavy in terms of file. one thing you can do is leave your file in grayscale to reduce size. so if you have the same size of the drawin g but using A. Illustrator you can see the difference in size and quality. Photoshop is not adequate great to line art drawings cause is not a vectorial program. but mainly peoples use the photoshop but with a small DPI. my Bismarck have more 251 centimeters and is coloured but the size is small.
I don't use CAD but this program is better than illustrator because can so much more resources than 2D.
to not complicate this if you can print in your office or home with a good quality use your file(jpg) and print it and see what quality gives. if ok don't loose your time. i wait you understand this book i write here
