Pilou,

>> Yes that works for the normal options but not for the "number point" option! ;) <<

I had preempted this query with additional note in previous post. The NumPoints option allows for rebuilding of input curves. In the instance of sweeping from a circle to a rectangle the resulting surface will be a polysurface with multiple seams. If however a single surface is desired it can be achieve by rebuilding the profiles so they have similar control points. Of course unless the number of points is set extremely high the polyline shapes such as the rectangle with lose definition.

If this still not clear perhaps Michael could phrase what I am trying to say more eloquently.
