well looks like i have to cut strips from 0.02" material and use a brake to make them, so was wondering what size sheet to get. Unless others have an alternative.
Ok, now see what your talking about.
That is certainly a depends question, mostly depending on if it sheared to a line and then that line works for the next one. Or if it is cut out each piece with the corresponding waste. So I don't think anyone will commit to that answer. With your CNC ability this would be easy for you to lay out each, (depending on your cutting/piece method) and then you can share what you come up with, or at least one worked for you.
As you know this is easy to draw out..
How I draw such:
form square box on the longest axis of your longest rib.
draw your two lines with min and max distance (width and length) at ends.
draw your next rib (hopefully using this just made cut line) and Z them back and forth for min. waste.
Your flanges will all be the same, so only length varies.
Then you can estimate at the same time all of your gussets required for this... pretty soon you have your
"sheet size"
