This was very helpful. I am a math idiot but this was very clear and easy to follow. I frequently need to calculate frustrum patterns for different metalsmithing and engraving projects. Occasionally I can do it with dividers but so often it just isn't practical to do it in that manner.
(Small original radius*diag distance) / (large original radius - small original radius) = small cone radius. Add diag distance to small cone radius to get large cone radius.
Thanks Mark. An oblique cone was what I was thinking, as you say it all comes down to the worker. Seems when you actually put the pattern on the sheet, everything changes when you start folding or rolling, especially on stainless. Thanks again 👍

Good to hear it was of use to you. Cheers
Thanks 🙏

Would you apply a similar method for an offset cone or use the radial line method instead?
