=Step 1 (latest update 2006-01-06):=
 
Download and install the LDraw Parts Library.
<pre>
user$ cd /tmp
user$ wget [http://www.ldraw.org/files/unix-complete.tgz http://www.ldraw.org/files/unix-complete.tgz]
...
user$ su -
Password:
root# cd /usr/local/share/
root# tar xzf /tmp/unix-complete.tgz &amp;&amp; echo OK
...
OK
root# mkdir -p ldraw/bitmap
root# chmod a+w ldraw/bitmap
root# chown -R root.root ldraw
root# exit
exit
user$
</pre>
 
=Step 2 (latest update 2006-01-06):=
 
To view ldraw model use [http://ldview.sf.net LDView].
You can install RPM or tar.gz version (available on
[http://sourceforge.net/project/showfiles.php?group_id=120592&package_id=131411 sf.net]),
or build from source.
To install LDView3.tgz (root permission is not required):
<pre>
user$ tar zxvf LDView3.tgz
user$ cd LDView3
user$ ./LDView
</pre>
To install from RPM (root privilege is required):
<pre>
root# rpm -i ldview-3.0-1.i386.rpm
</pre>
To build from source:
<pre>
user$ su -
root# cvs -z3 -d:pserver:[email protected]/cvsroot/ldview co LDView
root# cd LDView/QT
root# ./makeall
root# make install
root# exit
user$ LDView
</pre>
 
=Step 3 (latest update 2002-05-23):=
 
Install LDGLite. LDGLite is a rather
efficient tool for showing building instructions &quot;on the fly&quot;, when you
download them as &quot;<code>.dat</code>&quot;, &quot;<code>.ldr</code>&quot; or
&quot;<code>.mpd</code>&quot; files from the web.
<pre>
user$ cd /tmp
user$ wget [http://ldglite.sourceforge.net/ldglitesrc0_9_5.zip http://ldglite.sourceforge.net/ldglitesrc0_9_5.zip]
...
user$ unzip -uoa ldglitesrc0_9_5.zip
...
user$ cd ldglite
user$ make -f makefile.linux &amp;&amp; echo OK
...
OK
</pre>
 
There is a small risk that you may run into errors at this point, if
your system lacks some libraries. These errors will probably be of the
form <code>.../bin/ld: cannot find -lX11</code>. If you don't know how to
handle this, please contact an experienced Linux system
administrator.
<pre>
user$ su
Password:
root# chown root.root l3glite l3gledit ldglite readme.txt
root# mv l3glite l3gledit ldglite /usr/local/bin
root# mv readme.txt /usr/local/share/ldraw/ldglite.readme
root# exit
exit
user$ cd ..
user$ rm -rf ldglite
</pre>
 
Now you should be ready to run LDGLite - as the command ldglite - but
since the LDraw library has been placed differently from what LDGLite
expects, you have to set the environment variable LDRAWDIR to that
directory (/usr/local/share/ldraw). You can do that in your runtime
configuration scripts, just before you run ldglite, or you can create a
script that sets LDRAWDIR and then calls ldglite. I have chosen the last
of these three solutions (where I also make sure that there is no limits
on the stack size):
<pre>
user$ su
Password:
root# cat &gt; /usr/local/bin/ldglite-run &lt;&lt; THE-END
? #!/bin/tcsh
? setenv LDRAWDIR /usr/local/share/ldraw
? limit stacksize unlimited
? /usr/local/bin/ldglite \$*
? THE-END
root# chmod a+x /usr/local/bin/ldglite-run
root# cat &gt;&gt; /etc/mailcap &lt;&lt; THE-END
? application/x-ldraw;/usr/local/bin/ldglite-run -mc %s
? application/x-multi-part-ldraw;/usr/local/bin/ldglite-run -mc %s
? THE-END
root# exit
exit
user$
</pre>
 
=Step 4 (latest update 2002-05-23):=
 
Now your browser should be ready to open LEGO building instructions
directly in LDGLite, when you click on links to them on the internet. You
can test it by clicking on [http://jacob.sparre.dk/LEGO/Byggevejledninger/Tux/tux.dat tux.dat],
which should open a window with building instructions for a penguin (Tux,
the mascot of Linux). You may have to restart your browser to make it
recognise the existence of LDGLite.

LeoCAD is a great 3D editor for Linux (and Windows) which has offered
several improvements to the straight LDraw .dat format. It supports some
basic animation (via keyframing) and can also export to 3DStudioMax,
POV-Ray, and Alias Wavefront.

Step 1: Download ans Install the LDraw Library

  • Go to the LDraw.org Update page and download the latest complete.zip
  • Unzip complete.zip in the directory of your choice

Step 2: Install LDCad

  • Go to http://www.melkert.net/LDCad and download the Linux version of LDCad
  • Unzip the package into the directory of your choice
  • Run LDCad
  • When asked for the location of the LDraw Library, use the directory you unzipped complete.zip into.

Step 3: Making Building Instructions

There are currently two ways to create LEGO building instructions on your computer. You can either write/edit the raw text LDraw files or you can use an interactive drawing program, where you can move pieces around on the screen. If you chose the former method, you should just use your usual text editor and skip this step. If you would like to try the latter method, you should use LDCad.

Step 4: Dive in

Learning how to use your new editor or understanding the LDraw file format may be a challenge, but with a little practice you will get the hang of it.

Help!
