Joey already show us how to use the Follow Me Tool, but as many of you are asking how to make a Domo...here is a way to do it...



With the Circle Tool draw a circle. Before dragging to draw the circle, type 50 (and Enter) or more to make a more "rounded" one. With the Pencil draw 2 lines. Remember that in SU drawing and "closing" with lines is the same as in Flash: you are "cutting" into pieces that face. Erase the rest.




Now rotate the figure 90 degrees. And watching from the down side draw a circle with his center in the vertical side of the "quarter circle"




The new circle has to intercect the other object like this. Now, with the Follow Me Tool "mouse over" the quarter circle and follow the border of the "complete" circle to close the Dome. Practice it. If it is not closed, make Ctrl Z and try again.




Now explore with differents type of "quarters". Adding or substracting small pieces in the curve you can make "textures" to the Dome.




Finally, erase the surfaces below the Dome.
