How do you make blueprints?

That is great info, using a cad program is the fastest way of scaling.

With autocad you can make the drawing 1:1 then scale it to the size that you want. Plot to a pdf, email it to whomever you wish. They can then take the file to your local printer and have it plotted.

Here is one that I have been working on. 1/16 scale Bridge master ext.

You can also search the web for free cad software there are many different cad programs available. Learning the software you get has a large learning curve.

Sketching things out first always helps.

Here is just one of many, http://www.cadstd.com/

good luck, and if you have questions just ask.
