Dome Radius

[KLS]

Just wondering if there is a way to specify the radius of a dome?
Thanks

KLS,
Not to my knowledge. The dome size is controlled by the height and carve region. So, the smaller the carve region, and deeper the depth, the smaller the radius is. If you want to trig out the approximate dome radius, i can post a formula for you...

Ron,
Thanks for the reply. What I'm needing to do is cut a 14" radius across 2 3/8", 19.5 " long. Maybe there is a better function besides dome to accomplish this?

KLS,
I have never checked the accuracy of this function but it calculates out to a .05 depth on 2.375 width equals a 14" radius. It should work.

Hi Ron,

What is the formula you used? Thanks in advance!

Arc height when you know the chord length and radius:

B = R - sqrt( R^2 - (A/2)^2 )
(B = Arc Height) (R = Radius) (A = Chord Length)

Said as:
B equals R minus the square root of the quantity R squared minus A over 2 squared

Thank you, Ron!
