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)
INPUT:
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.
OUTPUT:
srf : cylindrical surface patch
Description:
Construct a cylinder or cylindrical patch by extruding a circular arc.
