Simple Mechanical Design Program? (free?)

  1. Oct 18, 2009 #1
    Hi,

    I'm designing a product using very very simple springs and gears and was wondering if there was a good software that can help test designs, preferably an inexpensive program.

    The design itself is very simple, and I don't need full blown CAD or anything that stout just yet.

    Nevermind - I just drew it by hand - design is simple enough to test with prototypes.

    Years and years ago (about a decade), I took mechanical drafting in high school (complete with old-skool(TM) drafting machines, exhortations to rotate the lead to maintain constant line thickness, and erasing shields).

    To this day, I draw (admittedly simple) one-off mechanical / prototype drawings with H or 2H lead and dimensioning, and then just photocopy the drawing to give to the machine shop (which conveniently eliminates the gridding, increases the contrast, and prevents smudging / destruction of original).

    Nice skill to have when you need something quick and dirty, and good way to work on the mental imaging / visualization abilities.

    Yeah, I like to draw, and the concept I'm working on is super simple. I need to go read up on motor sizes, battery capacity, etc., now!

    You might want to check Solid Edge for a Free 2D CAD program.
