solidworks tipsWhen you’re sitting at home alone gazing into the light fixture and wondering if you caught all the changes in a drawing that was just released, here’s an absolutely simple way to wake up early, go in before anyone else finds out and do a drawing file comparison.

  1. Make a .PDF of the first drawing (or new drawing)
  2. Make a .PDF of the second drawing (or old drawing)
  3. Open both PDF’s
  4. Use Ctrl-Tab on each page to see the difference

Whoa, missed the wing-nut on that thingy-ma-jig. You just saved your neck. This is extremely useful when checking revisions of drawings. You can also do this to quickly to compare changes between other documents as well.
