    Carol I would put out a pm or email to Dave Richards. He has a blog and is a contributor to Fine Woodworking and incredibly helpful in the Sketchup Department.

    I aint got it right to draw anything in Sketchup let alone even think about how you do ogees.

    Thanks, Rob, I am hoping Dave will jump in.

    Don, I am looking for the methodology. I know what they look like. I have a defined distance and height. I need to know how to determine esthetically pleasing proportions of the convex and concave curves. Are they equal or some proportion of each other? Where is the center of circle the radius is taken from?

    Example: If I drew an isosceles triangle, offset the edge of the base and the height, where along the new hypotenuse would the centers of the circle from whose ark I get the curve lie?

    Carol, I found the following which explains how to draw an ogee. Look at figure 4-41. The only thing it does not explain is how to determine the ratio of the large curve to the smaller curve. The golden rectangle ratio?

    Your welcomed Carol. I just checked and the curve shown is based on the Golden Ratio. The distance from point B to C multiplied by the golden ration (1.61803399) gives you the distance from point C to A. So knowing the distance between lines A & B, you should be able to reverse engineer where point C should be.

    Carol, it is only a coincidence that I just looked in right now.

    Thanks Rob for the nice words.

    I guess I was answering the wrong question. Sorry.

    Dave, I didn't see you answer to the "wrong" question." Did you delete it?

    And did you have a Sketch-Up drawing process answer to my question now that I have Bill's resource for drawing lovely ogees?
