Graphics, Figures & Tables ⇒ Circular Arrow in the x-y Plane

[kmath]

Hello everyone,

I currently have this.

Code: Select all

\begin{tikzpicture}[
  cube/.style={very thick,black},
  grid/.style={very thin,gray},
  axis/.style={->,blue,thick}
]
  %draw the axes
  \draw[axis] (0,0,0) -- (6,0,0) node[anchor=west]{$y$};
  \draw[axis] (0,0,0) -- (0,6,0) node[anchor=west]{$z$};
  \draw[axis] (0,0,0) -- (0,0,6) node[anchor=west]{$x$};

  %draw the top and bottom of the cube
  \draw[cube] (0,0,0) -- (0,0,4) -- (4,0,4) -- (4,0,0) -- cycle;
  \draw[axis] (2,0,2) -- (2,4,2) node[anchor=west]{$v$};
\end{tikzpicture}

It's a square in the x-y plane and vector v running perpendicular to it. I'd like to add a circular arrow around v indicating the plane is rotating around v. Any ideas?

Thanks,
Kevin

It's easier to use tikz-3dplot here. The output is attached.

Code: Select all

\documentclass[11pt]{standalone}
\usepackage[T1]{fontenc}
\usepackage{tikz,tikz-3dplot}

\begin{document}
  \tdplotsetmaincoords{75}{120}
  \begin{tikzpicture}[
    tdplot_main_coords,
    >=stealth,
    cube/.style={very thick,black},
    grid/.style={very thin,gray},
    axis/.style={->,blue,thick}
  ]
    \draw[axis] (0,0,0) -- (6,0,0) node[black,anchor=north east]{$x$};
    \draw[axis] (0,0,0) -- (0,6,0) node[black,anchor=north west]{$y$};
    \draw[axis] (0,0,0) -- (0,0,6) node[black,anchor=south]{$z$};

    \draw[cube] (0,0,0) -- (4,0,0) -- (4,4,0) -- (0,4,0) -- cycle;
    \tdplotdrawarc[->]{(2,2,0)}{0.5}{45}{375}{}{}
    \draw[axis] (2,2,0) -- (2,2,4) node[black,midway,anchor=west]{$\vec{v}$};
  \end{tikzpicture}
\end{document}

Wow. You owned that. Is there a "thumbs up" button to give you a personal point or is it enough to click the "checkmark?"
