Shape script for a box with no fill

[Glassboy]

Hi there.  How do I create a shape script for a rectangle with either no fill or a transparent fill.

I want to stereotype a UML node as a network but have it behave graphically like a boundary, rather than your standard 3D filled box.

Use strokepath(), e.g.:

Code: [Select]

shape main
{
    startpath();
    rectangle(0,0,100,100);
    endpath();
    strokepath();
}

Thanks.  Can I do anything to the pen beyond changing the colour and thickness?  aka can I draw dotted lines or similiar with strokepath?

Belay that question.  I found setlinestyle .

Yes, look in the help for SetLineStyle.
