Graphics, Figures & Tables ⇒ PSTricks | Draw a Brick

[svend_tveskaeg]

Hi all.

Consider the following MWE (inspired by this topic) where I try to draw a brick:

Code: Select all

\documentclass{article}

\usepackage{auto-pst-pdf,pst-solides3d,pstricks-add}
%\usepackage{siunitx}
\definecolor{nicered}{rgb}{0.796,0.255,0.329}

\begin{document}

\begin{figure}
 \centering
 \psset{unit=5cm,viewpoint=10 -30 15 rtp2xyz,Decran=9}
  \begin{pspicture}[solidmemory](-5,-5)(6,12)
   \psSolid[object=parallelepiped,a=2.28,b=1.08,c=0.54,RotZ=30,fillcolor=nicered,name=brick,action=draw*](0 0 0)
   \multido{\iA=0+1}{8}{%
     \psSolid[object=point,definition=solidgetsommet,args=brick \iA,action=none,name=P\iA]
     \uput[90](P\iA){$P_{\iA}$}
   }
%  \psset{offset=12pt,nrot=:U}
   \psSolid[object=line,linecolor=green,args=P0 P4]
%   \ncput*{$h = \SI{5.4}{\cm}$}
   \psSolid[object=line,linecolor=green,args=P4 P7]
%   \ncput*{$b = \SI{10.8}{\cm}$}
   \psSolid[object=line,linecolor=green,args=P7 P6]
%   \ncput*{$l = \SI{22.8}{\cm}$}
  \end{pspicture}
\end{figure}

\end{document}

I am trying to label the green sides (which should not be green in the finale drawing). I would like to label them as in the example at the bottom of page 71 in the pstricks manual, i.e., with offset and lines with arrows as |-|, but (of course) \ncput* is not working. Furthermore, I would like to put a node $P_i$ at every corner of the brick, but \uput seems to have no effect here.

How do I do these things?

Thank you in advance!

you cannot mix 2d and 3d functions. Drawing in 3d with perspective view and hidden lines and surfaces is a bit more complecated as the trivial 2d stuff.

First the box:

Code: Select all

\documentclass{article}
\usepackage{pst-solides3d}
\begin{document}

 \psset{viewpoint=10 -30 15 rtp2xyz,Decran=30}
  \begin{pspicture}[solidmemory](-5,-5)(6,12)
   \psSolid[object=parallelepiped,a=2.28,b=1.08,c=0.54,RotZ=30,
     fillcolor=red!30,name=brick,action=draw*]
   \multido{\iA=0+1}{8}{%
     \psSolid[object=point,definition=solidgetsommet,args=brick \iA,
       linecolor=blue,name=P\iA]}
   \psSolid[object=line,linecolor=green,args=P0 P4,linewidth=5pt]
   \psSolid[object=line,linecolor=green,args=P4 P7,linewidth=5pt]
   \psSolid[object=line,linecolor=green,args=P7 P6,linewidth=5pt]
  \end{pspicture}


\end{document}

See the first example in http://tug.org/PSTricks/main.cgi?file=E ... /Gallery3D how to place text in the 3d space

Hi Herbert.

I have accomplished (most of) what I want:

Code: Select all

\documentclass{article}

\usepackage{auto-pst-pdf,pst-solides3d,pstricks-add}
\usepackage[locale=DE]{siunitx}
\definecolor{nicered}{rgb}{0.796,0.255,0.329}

\begin{document}

\begin{pspicture}[solidmemory](-4,-2)(4,1.5)
\psset{viewpoint=10 -30 15 rtp2xyz,Decran=30}
\psset{fontsize=20,linewidth=2pt}
  \psSolid[
    object=parallelepiped,
    a=2.28, b=1.08, c=0.54,
    RotZ=30,
    fillcolor=nicered,
    name=brick,
    action=draw*
  ]
  \multido{\iA=0+1,\iB=1+1}{8}{%
    \psSolid[
      object=point,
      definition=solidgetsommet,
      args=brick \iA,
      name=P\iA,
      action=none
    ]
  }
  \pspicture[showgrid,solidmemory](-4,-3)(4,2)
%    \pcline[offset=12pt](P6)(P7)
%    \ncput*[nrot=:U]{$l = \SI{22.8}{\cm}$}
    \rotatebox{-7}{\rput(-0.8,-1.65){$l = \SI{22.8}{\cm}$}}
    \rotatebox{34}{\rput(1.8,-3.1){$b = \SI{10.8}{\cm}$}}
    \rotatebox{-1}{\rput(4.6,0){$h = \SI{5.4}{\cm}$}}
  \endpspicture
\end{pspicture}

\end{document}

Issue: I would like the label text to be typed in math mode. (I had a look at the examples in section 11.12 of the pst-solides3d manual, but to the conclusion that it is not the way to go.)

Damned! I edited the wrong post.

the math mode is not possible here. All characters are passed to PostScript and then set. Use

Code: Select all

\pspicture[showgrid,solidmemory](...)(...)

and then put all math stuff with the default 2d macros like \uput or \rput. Later you can delete the showgrid option.

Okay. I have done the following:

Code: Select all

\documentclass{article}

\usepackage{auto-pst-pdf,pst-solides3d,pstricks-add}
\usepackage[locale=DE]{siunitx}
\definecolor{nicered}{rgb}{0.796,0.255,0.329}

\begin{document}

\begin{pspicture}[solidmemory](-4,-2)(4,1.5)
\psset{viewpoint=10 -30 15 rtp2xyz,Decran=30}
\psset{fontsize=20,linewidth=2pt}
  \psSolid[
    object=parallelepiped,
    a=2.28, b=1.08, c=0.54,
    RotZ=30,
    fillcolor=nicered,
    name=brick,
    action=draw*
  ]
  \multido{\iA=0+1,\iB=1+1}{8}{%
    \psSolid[
      object=point,
      definition=solidgetsommet,
      args=brick \iA,
      name=P\iA,
      action=none
    ]
  }
  \pspicture[showgrid,solidmemory](-4,-3)(4,2)
%    \pcline[offset=12pt](P6)(P7)
%    \ncput*[nrot=:U]{$l = \SI{22.8}{\cm}$}
    \rotatebox{-7}{\rput(-0.8,-1.65){$l = \SI{22.8}{\cm}$}}
    \rotatebox{34}{\rput(1.8,-3.1){$b = \SI{10.8}{\cm}$}}
    \rotatebox{-1}{\rput(4.6,0){$h = \SI{5.4}{\cm}$}}
  \endpspicture
\end{pspicture}

\end{document}

Can I somehow use the defined nodes P0,...,P7 within the

Code: Select all

\pspicture[showgrid,solidmemory](-4,-2)(4,2)
 ...
\endpspicture

environemt?

no, the reason why I told you to use absoulte coordinates which can easily been find with the 2d coordinate system, drawn by showgrid

Okay. Thank you very much for helping me!
