[QUOTE="Nena, post: 270154, member: 7861"] Need some help! I have found a simple diamond diagram on facetdiagrams and i want to draw the diagram in my software but if i calculate the hight of the pavilion with the angles, the messurements arent correct. How can this be?! What is the solution?! I have used the 42.10 and the 41.00 degrees. If i draw the angles with the heigth in my CAD software then the pavilion heigth is ore to long or to short?! What am i doing wrong! Diagram: [url]http://www.facetdiagrams.org/database/files/pc01006.html[/url] Drawing is in inches as at the diagram [img]http://www.88i.nl/images/degrees_a.jpg[/img] [img]http://www.88i.nl/images/degrees_b.jpg[/img] Or do i need to calculate from the bottom. I feel stupid :) it has been some years i calculated these angles... 3d results (these messurements ar not correct yet) three positions [img]http://www.88i.nl/images/degrees_c.jpg[/img] [/QUOTE]
