    It is indeed a good solution to that shape. Looking at the shape Wade ended up making to complete his dome that is also a good solution. The biggest problem with Revit massing I've always run into is that creating non-uniform shapes is very finicky and not intuitive. Great steps were made with the 2010 revision to massing and hopefully we continue to see more additions to surface editing added to the program.

      I agree very finicky I find my self using a Generic Family Model as a massing tool sometimes for these kind of applications.

      As far as Max and Shech up we do not have these programs at this point. I can only use the tools we are given.

        Start on Horizontal plane with the base Elipse.
        Then add the central elipse on the centre vertical cross plane to match the length required and set to width (height required-3')
        Image 1 and 2
        Move on to the width cross vertical plane and add an elipse extanding the width and height. Image 3.
        Then split the elipse and trim it back to the horisontal reference plane. Image 4
        repeat this by duplicating the reference plane and adding an elipse to the plane matching it up with the underlying width of the base elipses for width and height. The higher the number of intervals the smoother you eliptical dome will be. Image 5
        THe tricky part is finishing off the dome. I very small profile/line is needed at the very end of the form to finish the CREATE FORM. Make sure that this line (form) is also on a vertical plane. Image 6
        If need be I can make a video bit the video posted earlier should be more than enough to get similar shapes.

          Actually I did a complete study on this one... Wanted to create exactly this form only with the cross section that followed the catenary line. This is how I did it:

          1. Create groundbase form out off two elipses
          2. Set up a number of refplanes perpendicular to the center axis (so you get cross sections). On the center axis draw a vertical elips with the desired height.
          3. Using 3D snapping you can now draw elipses on every refplane which snap to the intersections of the base elips and vertical elips
          4. Close all elipses with a baseline.

          5. Select all the cross-section elipses and Create Form. Here's a picture of the endresult of the ranting above:
