  1. I am in the process of creating an AutoCAD library of SMT components. Can
    anyone point me to a good source of outline drawings with dimensions
    (including pads) that I can use as a reference? Better yet, does anyone
    know of a source, preferrably free, of AutoCAD blocks of SMT components?

    Thanks in Advance

    rip em from a library in a circuit cad program, eagle has a whole lotta
    smt layouts in the free version, just go into the editor and export, or go
    by coordinates and manual copy.

    Hello Jim,
    But I suggest to still verify them against manufacturer data sheets.
    Eagle libraries are AFAIK gathered in a voluntary contribution fashion
    so there could be inconsistencies. Data sheets almost always contain the
    recommended foot prints and then you have a company like TI or National
    behind that recommendation.

    Regards, Joerg

    eagle is a good source, not of neccessity a great one, it'll be accurate
    most of the time, and besides, a good source was asked for.

    Wrong. Eagle libraries are made by a full-time employee at CadSoft (the
    Librarian) who does nothing else but make footprints.
