[pstricks] some questions on pst-solide3d

[Zbigniew Nitecki]

Thanks again, and sorry, one more question (I guess the short term was  
shorter than expected :-):  can one use \multido within  
\pstsolides3d?  I want to put some vectors along the centerline that I  
drew on the Moebius band, perpendicular to the band.   So I need for  
multiple values of \rv to place a vector with arguments (-sin \rv\cos  
2\rv, -sin \rv\sin 2\rv, cos\rv) at location
(2 cos 2\rv, 2 sin 2\rv,0).  The addition to my previous code of
*************************************************
		\multido{\rv=0+20}{18}{%
			\psProjection[object=vecteur,
				linecolor=red,
				args= \rv\space Sin \rv\space 2 mul Cos neg %
					 \rv\space Sin \rv\space 2 mul Sin neg %
					 \rv Cos%
			](\rv 2 mul Cos 2 mul, \rv 2 mul Sin 2 mul, 0)
		}	
**********************************************************
(also with \space after the \rv in the location, or with ! inside the  
parentheses) crashes.
Am I still doing something stupid with \space or !, or does \multido  
not apply here (and if so, is there something that does?), or does  
\psProjection only work with vecteurs that have two arguments?  or...?
