In these situations, top posting is probably the easiest method. A forum is completely different. In this situation, top posting is very inconsiderate. You have already heard all the reasons. Best Regards, Mike Monett Mike, Just for your pleasure I am posting at the bottom.

And most importantly: If the list owner says top posting is a no-no, then top posting is a no-no. Point. He sets the rules. He could even require that we use a violett font and include pictures of rosa ponies in all our mails and we'd have to adhere to it.

Yeah, you would use offset_sweep twice for the top and bottom of the skin object. I did a quick test: up(2.5) offset_sweep(botBot,h=.5,top=os_circle(r=.5)); and you get the result below. To get it really nice looking you'll need a custom profile that better matches the slope of your shape, with a smaller rounding arc.
