I'm asking Maple for simple things only, yet still (5 years later) I get nothing.

I'm creating 3 contour plots for potential functions in 3 bordering regions of 3-space,

because a continuous potential function isn't possible to define. 

After an entire worksheet worth of variable definitions and series expansions, i say simply:

CPA:=contourplot3d(VI(a,b,c,d,e)......)

CPB:=contourplot3d(VII(a,b,c,d,e)......)

CPC:=contourplot3d(VIII(a,b,c,d,e).......)
