Basically you have to define your own primitives by programming. You could use ParametricPlot to define the 3D circle or colored Polygon. The Presentations package has these built-in as 3D primitives. Circle3D[position, normal, radius, anglerange] Disk3D[position, normal, radius, anglerange] The extra element needed over 2D circles and disks is the specification of a normal vector. David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ From: David [mailto:lists at theflorys.org] Newbie question: Is there a simple way to convert a 2D graphic object like Circle or Disk (lets assume they are in the xy plane) into a 3D object? I want to be able to do a 3D rotation on, for example, a circle. Thanks for hints or solutions, David.
