    I'm an electronic engineer student I have to work with protel dxp 2004, in fact it's not matching with my competencies ( software development) so my questions will be silly :) but I need soon answers:
    I have to make a circuit board (38mm*38mm) , but I didn't find many component in the standard library (offering by Altium), I read many tutorial...I understand That I have to make my own library, for example I tried to make the footprint of the component "TPS54310PWP" (from Texas Instrument) , I download its datasheet but really I didn't understand how can create its footprint with this datasheet , I search components that have the same footprint with it but I didn't find, can any body help me please because when I read topics in forums people said that it's not difficult to make your own PCB!!!
    Even capacitor I don' t know how to make it's footprint for example I found capacitors 0402, 0603... 2220 but I have to work with a polarized capacitor 2816P what this means and how can I make it's footprint !!!

    Look at this document. It tells you all you need to know about the footprint for the TPS54310

    You would find it referenced in the datasheet for this device, which I'm sure you've read.

    I assume you know what 0402, 0603, etc mean, so the meaning of 2816 (if that's the component size and not a part number) should be obvious. In any case, finding the datasheet for the component will almost certainly yield the correct size pads for it.
