    blueprint reading

    Well I assume your in the welding fabricating business so I would ask a coworker or get with the shop foreman and go over some old prints I work with pipe isometrics on a daily basis I learned by asking the more experianced guys I don't think any book would help on its own just get a blue book a square a plumb bob and a pencil and soapstone and read your ISP make a cut list and go from there

      Hey Luis,

      A blueprint is usually nothing more than a front view (elevation) a side view (profile) and a top view...(plan) Since it is sometimes read around the world from where it's drawn, a bunch of other info and measurements are used to guarantee they'll be understood and the measurements will be the same. There are traditions to how you do those measurements (this is what you learn in drafting classes...but you can see the conventions if you just look at a lot of blueprints...)

      Here's a link that helps understand how objects are divided up into blueprint views.

      You do learn HOW to draw them and divide them up if you take a drafting class,

      programs like Google Sketchup allow you to move around the views and see them in 3-d where as older guys like myself had to do the 3 views on drafting paper and imagine the object when it was done.... So it's a different learning curve and it's frankly a dying art. Someday soon there will be only 3-d forms that you can view in rendering programs...and you'll be able to print out the 3 views with no work at all.

      I read a great book on how to quickly see things in your mind from blueprint view called RAPID VIZ and it showed how to think quickly and visualize quickly.

      So you can start there.

      Another way to learn is to take an object that is pretty regular, like a box or something, and draw a front, side, and top view of the thing and match the measurements to a if the box is 8 inches high you use 1/2 scale and draw it 4 inches high on the paper.

      You can learn it and you'll find it's easy. Just a new skill

      Good luck

        I took a Welding & Blueprint reading course at my local adult education school. It was a 900 hour program with a day or two every week set aside just for blueprint reading. It was extremely helpful cause your working specifically with all the different welding symbols & lines & the different materials. In my mind unless its drafting for welders a drafting class is only a little helpful. If you dont know what the symbols mean your still pretty clueless.
