I've just starting using the free 30 day trial subscription, with the intention of creating dome construction plans. I am impressed with your video presentation. It's quite good. Would you be interested in taking on a project?
Hi, thank you for the video and making clear what the angles mean. If I understand it correctly, I don't have to care about the black angle (for strut A it's 79.2°), because this dihedral angle results automatically by connecting two triangles?
The black angle is the inclination of the side an imaginary pyramid. It does not result by connecting two triangles. It results from assembling the compound miters at each strut end (of one triangle). Some people also call it "strut rotation". If you rotate a strut the inner edge will move out of the original imaginary pyramid. In order to cut it flush again, you need to cut this longitudinal angle. So it really has 3 names: 1) pyramid side inclination 2) strut rotation) 3) longitudinal cut angle. What the calculator does is it takes the triangle angle and this very strut rotation and spits out compound miters. That is really all it does ;-). In one video I show how I made a little javascript program that does the exact same thing. I think it is called "Zollinger".
@@alwaysgreener2856 Ok cool thanks. In the end that means I don't have to cut the black angle? And do you know by chance where to find the "Zollinger" program?
@@alwaysgreener2856 sorry for the late response i just saw this but where does it show me the length of the struts. where do you find and what exactly are you referencing to when you say the “longest edge”?
@@alwaysgreener2856 nevermind i understood what ur talking ab thanks for the help but im just confused about what the units the numbers are in. is it millimeters?
There is a Facebook Group called Acidome you might find more answers there. the biggest problem in my eyes is stability (which is ultimately not really what you need for a greenhouse though). In the beveled frame method the bevel is applied to the width (length > width > thickness). In acidome the bevel - if at all - is applied to the thickness. When you do beveled frame you are limited by the width of your saw blade. So you will see alot of beveled frame GeoDomes with a small width. The result is it only fits one screw at each end. This is a huge disadvantages when sheer forces start working on the vertices. Just do a test. Screw two struts together ontop of each other with 2 scews at one end. Try to rip it with your hands as though you wanted to bend the screws. Then remove 2 screws and try again. This is of course only one aspect "stability". This however the one that bothers me the most.
@@amousavizadegan In acidome there is only 2 angles "red & blue". So you have a 50% chance to get it right. One is the blade tilt and the other one is the base of the miter saw. Start with the equilateral triangle.
Exactly the questions I had. Thanks for making this video!
Hi, you solved the most headache part of the diagram. thank you very much !!
Thank you for the detailed explanation. I was finally able to understand.
@Always Greener Acidome uses 90 as a reference degree based on the mittersaw. So all calculation are made like you said "90 - x".

@@alwaysgreener2856 Thanks... just sent you an email.
Thank you its really very helpful!

how do you determine what length each of the struts are supposed to be
you chose a diameter for a dome you want and all the strut lengths depend on it. The length is always the longest edge.

I am wandering what are the pros and the cons of this acidome design compared to beveled frame of Paul Robinson.

@@alwaysgreener2856 Thanks for the detailed answer. Much appreciated.
Minute 2:40 "Without the red angle don't turn on themselves" is wrong. Should have said "without the blue angle the struts don't turn on themselves".
My question is the angle on top of struts which I cannot find any reference on how to use it or include it in the cutting of a struts.
