Onion Domes

Resurrection Church   I really like the “onion domes” you often see on Russian churches (Resurrection Church (right, from Wikipedia)). It is also a nice design element to put on the end of a board that would otherwise just be hanging out in the breeze.  If you imagine taking a slice through the middle of a dome or pressing one flat (like a flower in a book), you get the idea. You can draw them free hand with just a circle/ellipse template, square, pencil and divider (or ruler) or crank up your drawing program. For the project I just finished, I did them free hand and for this post, used CAD. I drew them somewhat backwards, by starting with a fixed board size (2” x 2” and 3.5” x 2” in this case) and smooshing the circles until I liked the shape.
– The circles touch at their tangents so the transitions are smooth, I did no blending.
– The top ellipses are centered on the board corners. That makes laying out both sides easy and makes the “point” look “right” and transitions smooth.

    Sir,

    I have been trying to find out resources to build small onion domes say 1.5′ dia at the base and about same height. I have searched the internet and for books on the subject, have not been able to find anything. Can you please help me out on this.

    Appreciate your help.

    Best regards,

    Daya Singh
