How do you make a technical drawing with pen and paper?

Technical drawings are made on the computer with CAD, Computer-Aided-Design. How can you make a technical drawing with pen and paper?

    Pretty much the same way - I’m old enough to remember the ol’ drafting table with the T-square, compass and triangle.
    It’s just a heck of a lot more tedious - and aggravating if you make a mistake or some loon wants to add changes or modifications to the original design.

    If you please add more details about the conditions, so that people could help you

    Anyway, drawing tools ( pencil,ruler, protractor ,..etc) are used in technical drawing. But if you mean that you want to use only a “pen” and a paper, then you do one of the following :

    1- Either you use free hand sketch, but it will be rough and less tidy than mechanical drawing. Just move your hand straightly and you will get good results

    2- Or you may use the “shapes ruler”, it has some technical shapes inprinted in the ruler that allow you to pass your pen and draw the shapes, like circles, arrows, and many technical symbols. You can buy one from the stationary markets(shops).

    The process is not as different as you’d think. Some disciplines - like industrial design - still start with hand drawings.

    The tools of the trade are a draftsman’s table, t-square, triangle, templates, pencils, vellum or a plastic material whose name escapes me at the moment, and the most important tools of all: eraser and shield.

    In my hand-draw era (1979 ~ 1987) these drawings were “digitized”, in my case entered as net lists for PC board design, by a CAD operator. Of course there was a tedious cross-check process of verifying the drawing vs. the nelist vs. the layout. Seems dumb today but that’s how things were done.

    There’s free or very cheap tools now for just about any kind of technical drawing. For mechanical and architectural stuff try Google Sketchup.
