[QUOTE="Mr Magoo, post: 270171, member: 3008"] That's one of those brain annihilating questions but I think you are on the wrong plane. The vertical angle is 0* the horizontal is 90*. So 90 - 41 = 49* Using this calculator [url]http://www.cleavebooks.co.uk/scol/calrtri.htm[/url] Width: a = 0.5 Angle A = 49*. Hit calculate and it chucks out the answer length b = 0.435 Which, if I have this right matches the ratio P/W 0.435 in Gem CAD Could be wrong - its late. :) [/QUOTE]
