I have been working with the grasshopper spreadsheet posted by JayRay, though I'm not sure where I found it, since the download link seems no longer to work.

I've been puzzled by the formula in cell A6. It refers to cell B2, the pallet span, which already is defined as integer + 0.5, but the formula then adds another 0.5, seemingly double-counting. This results in an apparently incorrect pallet span angle as well as output values that disagree with Aydlett's table on page 266. Removing the 0.5 from either the formula or from the input cell brings most of these values into line with Aydlett, though still differing modestly in cells 6D, 6J, and 6K. Perhaps I'm using an earlier, uncorrected version of this tool, but it's all I can find.

Has anyone else been using this spreadsheet who might be able to shed some light on these issues or to post a corrected version?

I have looked at the Radial Vector Tool posted on the forum, but there seems to be no numeric output and no way to get an output in .dxf format, which I need since I have no CNC tools.
