Alternatively, you can use this shape script or something like it:
shape main
{
ellipse(0,60,100,100);
startpath();
rectangle(0,20,100,80);
endpath();
fillpath();
ellipse(0,0,100,40);
moveto(0,20);
lineto(0,80);
moveto(100,20);
lineto(100,80);
}
See the help file to find out what to do with shape scripts. In short, you will need to define a stereotype, define a shape script for the stereotype, and apply the stereotype to your database object. Any problems, please ask.
