Hi,

According to the Allegro PCB Editor 16.0 data sheet, "RF geometry and
circuit creation/editing" is an option only available for XL and GXL.
Though this feature may have additional benefits beyond just the shape
creation, at least for me, writing SKILL routines that provide these shapes
is a lot less expensive.

Regards,

Austin

  No takers? The only way I know of to create a spiral pattern (not with
variable trace widths) is add connect and use arcs. If you do need variable
width, creating a shape with arcs should do it.
