I don't understand my error below.  I am trying to draw a hemisphere  
with a cone cut out.

		\pstThreeDCoor[xMin=0, xMax=2, yMin=0, yMax=2, zMin=0, zMax=2]
			\pstThreeDLine(0,0,0)(\rt\space cos 0.707 mul,\rt\space sin 0.707  
				t cos \rt\space cos mul
				t cos \rt\space sin mul
				t sin%
%			\pstThreeDEllipse(0,0,\rz)(1 \rz \rz mul sub 0.5 exp,0,0)(0,1 \rz  
\rz mul sub 0.5 exp,0)%
With the last line commented out (as above) I get a picture, whereas  
when it is uncommented I get an error:
Error: /undefined in 0.0070.007mul
