Hi all,<br><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>Mikel<br>
