Reading basic engineering drawings (blueprints)

• • • Charles Skeen: Blueprint reading introduction (3 minutes)

    • WISC Online: Looking at the lines on an engineering drawing

    • WISC Online: Symbols for engineering drawings (Note: this goes into a little too much detail. Don't worry about memorizing the names of the kinds of symbols -- just make sure you understand what they mean)
