    W12 x 152 is a standard structural steel shape, you should be able to find the dimensions for this in the Appendix H your text refers to or just about any steel catalog. Draw it as though it looks like a capital letter "I".

    All the second bullet point says is that the dimensions for your foundation plan will go to the center of the "I". Once you've laid out your steel columns in the manner specified in the subsequent bullet points, vertical dimensions will run to the midpoints of the vertical section of the "I", and horizontal dimensions will run to the midpoint of the top (or bottom) of the "I". See below:

    Unhappy still confused

    STRUCTUAL DRAFTING.dwg

    hey guys i think im still dont understand the 20 steel columns- 14 spaced around the build perimeter and six within the interior. arrange these I-beam columns on foundation plan in four evenly spaced rows of five beams each. distance between center beams is 18'-0". and for the overall dimnesions part do i just make the rectangle length of 54' and 72' high?

    and about bullet point #4: how i make a 16 x 32 x 32 concrete footing?

    thanks agian guys

    attached here is my current drawing i know its not correct, but can you please tell me my problem. im pretty sure the measurement is correct.

    I believe you have your columns spaced at 18 inches, when they should be 18 feet.
    The concrete footing described is 16 inches tall by 32 inches square, so from the top, you just show that as a 32 inch square centered around the steel column. (BTW, that footing seems far too small for a W12x152 column)

    here's a quick video showing a top view of what page 8 describes.

    What would you recommend, size-wise, as a footing for a W12x152 column? Just curious. Thanks.

    Probably something closer to 60"x60"x24" with a bunch of #5 rebar in both directions. Without knowing the load it was taking, it's hard to say.
    Trying to explain the benefits of SolidWorks to a devout AutoCAD user is like trying to explain evolution to a creationist.

    Yeah, 5 or 6 ft square seems a bit more reasonable for a column that heavy.
