I'll just go ahead and paste this here out of the email I sent you, so others can see the answer, too:
Try the Paint tool. If you put it in Polyline mode, you'll get Write-on/Write-off controls in the Stroke Controls. To get an Ellipse or Rectangle, don't use the Circle or Rectangle modes. Instead, put it in Polyline, then Right-click in the Viewer, point to the PolyLineStroke (very last entry in the context menu), and choose Create > Ellipse, for instance.
Paint is a very deep and flexible tool, but it's not laid out as nicely as you might like, so it can be difficult to find the controls you need. Read the entry in the Tool Reference manual carefully, and take the time to poke at it to learn what all it can do.
