Basic Examples 
(4)
 

A simple curve:
[◼]
Intrinsic3DCurve
[Sin,Cos,5.5,2.18,0.015,0.01,2200]
Out[3]=
———
Increasing width, we get a ribbon-like surface (in fact, a ruled surface—the other edge has a displaced TNB frame):
[◼]
Intrinsic3DCurve
[Sin,Cos,5.5,2.18,0.19,0.01,2200]
Out[4]=
———
With a constant function:
[◼]
Intrinsic3DCurve
[1&,Sin,1.,1.,0.3,0.01,1255]
Out[5]=
———
A higher constant function:
[◼]
Intrinsic3DCurve
[Sin,3&,2.25,.5,1.,0.073,560]
Out[6]=
