<br>
I was trying to automatize some drawings using the multido package and
PostScript operations (mul, add...). Let's suppose I want to draw a 3D
vector rotating around the z-axis. The following works fine:<br>
<br>
\documentclass[a4paper,10pt]{article}<br>
<br>
\usepackage{pstricks}<br>
\usepackage{pst-3dplot}<br>
<br>
\begin{document}<br>
\begin{pspicture}(-4,-4)(4,4)<br>
\psset{Alpha=60,Beta=10}<br>
\pstThreeDCoor<br>
\pstThreeDLine(0,0,0)(0 cos,0 sin,1)<br>
\pstThreeDLine(0,0,0)(45 cos,45 sin,1)<br>
\pstThreeDLine(0,0,0)(90 cos,90 sin,1)<br>
\pstThreeDLine(0,0,0)(135 cos,135 sin,1)<br>
\pstThreeDLine(0,0,0)(180 cos,180 sin,1)<br>
\pstThreeDLine(0,0,0)(225 cos,225 sin,1)<br>
\pstThreeDLine(0,0,0)(270 cos,270 sin,1)<br>
\pstThreeDLine(0,0,0)(315 cos,315 sin,1)<br>
\end{pspicture}<br>
\end{document}<br>
<br>
But when trying to use multido, the sine and cosine commands seem to
not work, nothing appears on the output (except the axes):<br>
<br>
\documentclass[a4paper,10pt]{article}<br>
<br>
\usepackage{pstricks}<br>
\usepackage{pst-3dplot}<br>
\usepackage{multido}<br>
<br>
\begin{document}<br>
\begin{pspicture}(-4,-4)(4,4)<br>
\psset{Alpha=60,Beta=10}<br>
\pstThreeDCoor<br>
\multido{\rA=0.00+45.00}{8}{%<br>
\pstThreeDLine(0,0,0)(\rA cos,\rA sin,1)}<br>
\end{pspicture}<br>
\end{document}<br>
<br>
Is there any way to get this working? Why doesn't multido perform the
operations?<br>
<br>
