Annular Parts (Stents)

Hi

Could someone suggest a method to model annular, patterned parts such as stents ?

Design a repeatable portion in a flat sketch; if for example you can repeat
the pattern every 90 degrees layout a flat sketch whose baseline is exactly
(to as many decimal places as possible) 1/4 of the circumference of your
final diameter.

After you've layed out your sketch you can extrude as sheet metal and use an
insert bend to roll it to your desired radius (note: you need small
extension extruded prior to rolling that you can cut off later to make this
work) or use the wrap command to wrap the sketch onto a cylinder with the
scribe option. Use this to make a split line on the cylinder, then
surface offset, then surface thicken.
