nrbcylind

 
 NRBCYLIND: Construct a cylinder or cylindrical patch.
 
 Calling Sequence:
 
   srf = nrbcylind
   srf = nrbcylind(height)
   srf = nrbcylind(height,radius)
   srf = nrbcylind(height,radius,center)
   srf = nrbcylind(height,radius,center,sang,eang)
 
 Parameters:
 
   height    : Height of the cylinder along the axis, default 1.0
 
   radius    : Radius of the cylinder, default 1.0
 
   center    : Center of the cylinder, default (0,0,0)
 
   sang        : Start angle relative to the origin, default 0.
 
   eang    : End angle relative to the origin, default 2*pi.
 
 
 Description:
 
   Construct a cylinder or cylindrical patch by extruding a circular arc.
