    Free Truss member geometry calculator

    I needed to weld up some trusses for a project and just guessing at angles and distances wasn't working too well, so I stopped designing in CAD and wrote a spreadsheet.

    The attached is self explanatory because it contains a full written description and pictures as examples.

    I wrote it using LibreOffice under Ubuntu Linux and the '.ods' version is the original. The '.xlsx' version is one I exported from LibreOffice but I have no idea if it works under Windows since I don't have any Windows boxes.

    To my knowledge, I own:
    50% of all the plasma cutters,
    33% of all the TIG welders and
    20% of all the MIG welders on the island.

    I own 1 of each.

    Looks good under Windoz. I'll check it on the Linux box later. Thanks.
