How do you rip a pipe so it will give you the flat pattern?

Thanks,

    See example above

    What you do is draw your tube with a split circle
    extrude a surface using the split circle
    then use the sheet-metal tool to thicken that surface

    I find putting the k factor to 1 gives you a good flat pattern to work with.

    when I tried split with my pipe (made using frame tool) it splits straight through into two parts 
    is there a way of only splitting once? 
    Problem would be joining the two patterns on one face, if it's split in two 
    I have a pipe that is mitred then notch so there's a different shape on the two halves when it's flattened

    The best way to do this is probably do a thin cut (make it less than the "minimum gap" in the sheet metal feature):



    Note that I could even do a sweep instead of an extrude to split both frame members in one go in this case
