Geometric definition

is there a geometric definition on this curve's construction? i.e. how did the artisans construct the ogee shape? Xah Lee 10:31, 2005 Mar 17 (UTC)

Without looking this up anywhere, I've just changed parallel to tangential. -- Trevj (talk) 12:26, 27 March 2013 (UTC)[reply]

I have been looking into the geometry, and it seems that today ogees are universally depicted as 2 curves of the same radius, one rotated 180 degrees. That goes for diagrams in this article, other articles online, and for almost all ogee router bits (and every ogee router bit I found that specified the radius of the curves. Sample size: several dozen, I didn't count.). The curve is usually 90 degrees, except for large radii (and I suspect that is likely due to the common thickness of wood being around 3/4 of an inch).

But if you look at antique ogees, such as either of the stone arches pictures on this page, or the 2 Victorian moldings from my house that I just measured, the concave curve has a larger radius than the convex curve. And the curves seem to be around 60 degrees (based on eyeballing the 2 pictures, and in the 4 curves I measured on molding: all 4 appear to be 60 degrees of a curve before tapering into the next shape.)

Obviously those are small sample sizes. I would love to have more. Would also love to have a more mathematical description than "tapering."Skintigh (talk) 03:57, 29 October 2021 (UTC)[reply]

origin

Is Ogee short for something? i.e. is there a full Latin name

"Oh, gee"?

Can this be cited? I'm very skeptical.65.96.201.130 (talk) 14:17, 8 November 2008 (UTC)[reply]

Cyma recta or reversa

I would think an ogee is a cyma recta not a reversa. Or can ogee be used for both? See [1] for ogee as cyma recta. Notum-sit (talk) 08:31, 2 December 2008 (UTC)[reply]

Requested diagram

The photos are good illustrations but do not clearly identify which elements are of the shape being discussed. A diagram in which the shape is isolated would be helpful. Jim (talk) 15:48, 8 July 2009 (UTC)[reply]

Added an image from the molding page. Does that work? --76.98.88.59 (talk) 02:54, 15 July 2009 (UTC)[reply]

Ogee Clock

The picture of the clock doesn't seem to contain any Ogee curves (unless you count the beehive), and the title is definitely incorrect: the moulding of the clock is square bevelled, not Ogee. 122.176.243.137 (talk) 17:11, 15 September 2010 (UTC) Raj Mathur[reply]

Arch

Should not the concept of an arch be indexed off this page?

That was a big gap on this page. Now fixed, with edit summary acknowledgement to you. Thanks. --Old Moonraker (talk) 07:52, 27 June 2012 (UTC)[reply]

"semicircular"?

maybe my eyes or my thinking are not working correctly here but I cannot see (two) halfs of circles in the two drawings, but rather about (two) 1/4s of circles (and a completely different section of a circle in the wider (flatter?) bow of the tomb arch)?
