I think you're talking here about these images from the Boolean Merge topic in the help file?
To make those kind of rounded caps you generally want to use the Sweep command - you make 2 rounded curves that cross each other and use one as the profile and the other as the path, see some of these previous posts for some more illustration:
But if you're mainly focused on making a shape that is like a tube with an ellipse cross section, then it's probably better to draw the ellipse and then a path curve and use Sweep to build the shape directly as Brian shows above.
Basically if you want to create a shape that is generally tube like with some particular shaped cross sections, the sweep tool can construct that kind of thing - you draw the cross section for the profile and draw the path curve, then select the profile and run Sweep then select the path curve.
Check out the video tutorials here for some more details - Sweep is used in both the sunburst and the six-legged pod videos: http://moi3d.com/2.0/docs/tutorials.htm
