I have a problem with this code
\documentclass{article}
\usepackage{pst-3dplot}
\begin{document}
\begin{pspicture}(-3,-2.5)(3,4.25)
\pstThreeDCoor
\end{pspicture}
\end{document}
Error:
! Undefined control sequence.
\XC@usec@lor ...\expandafter \c@lor@to@ps #1#2@@
\else \expandafter \expand...
l.9 \end
{pspicture}
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., \hobx'), typeI' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
Do you anyone know what I do wrong?
Thank you!
pdflatex, which does not understand postscript. Try compiling withxelatex. – Bernard Jun 28 '19 at 09:39
