Hi, if you have version 6, lock up "RegionFunction" in the manual. Here is an example: fun1[x_]=x^2; fun2[x_]=2 x^2; ParametricPlot[{Sin[u v],Cos[u]},{u,0,1},{v,0,1},RegionFunction->Function[{x,y},fun1[x]<y<fun2[x]]] hope this helps, Daniel chuck009 wrote: > Suppose I have two lists of r and theta points that make up two curves in the x-y plane. I'd like to be able to draw a parametric plot of a surface that only draws the component of the surface between these two curves. I can create a table of the Polygons between the two curves directly but that's messy and time-consuming. Is there no other way to do this type of graphics programming? >
