The information has been validated and tested using Ubuntu 14.04 LTS. Any related information referencing Red Hat distributions such as Fedora have also been validated throughout regular use of the Fedora 20 OS release.
TODO:
 
the information on this page needs to be split up into the several pieces,
for example all documentation about LDView should go onto LDView's wiki page, not here!

===Basic setup (applies to any Linux distribution or operating system - Recommended approach)===
 
*Download the latest <code>complete.zip</code> from [http://www.ldraw.org/parts/latest-parts.html LDraw.org download page].
*Extract the <code>complete.zip</code> archive in the directory of your choice - your home directory is recommended for simplicity (<code>~/ldraw/</code>).
 
====Updating your parts list====
 
If, for any reason you have decided to alter the original parts directory (<code>~/ldraw/parts.lst</code>), Nathanel Titane has made a Linux native 'mklist.exe' equivalent: 'make-list'.
The make-list utility operates exactly like its Windows counterpart, and generates a 'parts.lst' file that can be either sorted by part number or part description.
*Download the utility [https://raw.githubusercontent.com/nathaneltitane/ldraw/master/make-list here] (right click: 'Save link as...')
*Save the utility as 'make-list' to your LDraw parts library directory (<code>~/ldraw/</code>).
*Run the utility in the terminal: <code>chmod +x make-list && ./make-list</code> and follow the prompts.
 
'''Note:''' If present, the previous version of the 'parts.lst' file will be backed up.
 
==Install an editor==
 
===LeoCAD (recommended)===
 
Leonardo Zide's LeoCAD is readily available for install for both Debian and Red Hat based distributions. You can download a no-install AppImage from https://www.leocad.org/download.html (recommended), alternatively, you can install the editor by looking for and installing the <code>leocad</code> package using your preferred package manager or command package management tool.

Download and Install the LDraw parts Library

Basic setup (applies to any Linux distribution or operating system - Recommended approach)

  • Download the latest complete.zip from LDraw.org download page.
  • Extract the complete.zip archive in the directory of your choice - your home directory is recommended for simplicity (~/ldraw/).

Updating your parts list

If, for any reason you have decided to alter the original parts directory (~/ldraw/parts.lst), Nathanel Titane has made a Linux native 'mklist.exe' equivalent: 'make-list'. The make-list utility operates exactly like its Windows counterpart, and generates a 'parts.lst' file that can be either sorted by part number or part description.

  • Download the utility here (right click: 'Save link as...')
  • Save the utility as 'make-list' to your LDraw parts library directory (~/ldraw/).
  • Run the utility in the terminal: chmod +x make-list && ./make-list and follow the prompts.

Note: If present, the previous version of the 'parts.lst' file will be backed up.

Install an editor

LeoCAD (recommended)

Leonardo Zide's LeoCAD is readily available for install for both Debian and Red Hat based distributions. You can download a no-install AppImage from https://www.leocad.org/download.html (recommended), alternatively, you can install the editor by looking for and installing the leocad package using your preferred package manager or command package management tool.

  • Install LeoCAD:
    • All systems (AppImage method, recommended): Go to https://www.leocad.org/download.html, select "Download LeoCAD for Linux", make the AppImage executable (chmod +x), and double-click to run.
    • APT-based systems (e.g. Ubuntu, Mint): sudo apt-get install leocad
    • YUM-based systems (e.g. Fedora): sudo yum install leocad
  • Run LeoCAD and point it to the LDraw parts library:
    • Go to View > Preferences... and set your library directory by either typing it in the field or browsing to it via '...'. Make sure to select the topmost directory (normally 'ldraw') that contains the 'parts' directory.

Notes:

  • LeoCAD can use either a zip file or a regular folder as its parts library directory.
  • You can start Leocad with a different library setup using: $ leocad -l <library directory path>
  • LeoCAD also supports setting the library path as a system environment variable like so: $ set LEOCAD_LIB=<library directory path>
  • LeoCAD supports redirection to the official LDraw parts library. If you have downloaded and/or set up the LDraw parts directory on your system, you can modify LeoCAD's preferences to use your library directory as its parts database. To do so, navigate to View > Preferences and browse to the corresponding directory under the 'Custom parts library' field.

LDCad

  • Go to LDCad's download page
  • Select and download the latest generic archive of the LDCad editor.
  • Extract the archive in the directory of your choice - your home directory (or a subfolder of it) is recommended for simplicity.
  • Run LDCad, follow the prompts and point it to the LDraw parts library. Make sure to select the topmost directory (normally 'ldraw') that contains the 'parts' directory.

Note: LDCad assumes you have GTK2 installed (just about any distro should have it). Make sure you have installed the required packages and libraries to avoid any issues.

LDGLite

LDglite is only available as a standalone 64bit binary for Linux. Compared to the other editors, it does pale in comparison to the amount of features present on the more modern ones. If for curiosity's sake you still want to install it, proceed as follows:

  • Download the LDGLite binary archive
  • Extract the archive in the directory of your choice - your home directory is recommended to avoid any file permission conflict or having to tamper with your system as 'root'.
  • Run LDGlite, right click on its background to get started.

Notes:

  • Make sure that the binary is set as executable before attempting to run it: $ sudo chmod +x ldglite
  • This specific standalone requires libraries such as the DRI-accelerated OpenGL libraries, glut, glu, libpng and zlib to be installed.
  • If, for whatever reason LDGlite fails to start by clicking on the binary, you may run it via a terminal and verify its output, like so: ./ldglite

MLCAD (Hybrid setup)

  • Install Wine via your distribution's package manager or application repository.
    • APT-based systems (e.g. Ubuntu, Mint): sudo apt-get install wine
    • YUM-based systems (e.g. Fedora): sudo yum-install wine
  • Download the MLCad archive.
  • Extract the MLCad_V3.40.zip archive in the directory of your choice - your home directory is recommended to avoid any file permission conflict or having to tamper with your system as 'root'.
    • Run MLCad by selecting MLCAD.exe and follow the usual prompts (LDraw parts library directory location and file type registration setup)
    • Select Wine as the default method to open an executable on your system and proceed with the previously mentioned steps.

Note: MLCad runs exceptionally well (Platinum status on Wine's AppDB scale). Any encountered problem, whatever it may be, should be troubleshooted or reported to the Wine developers as they are responsible for maintaining Wine's underlying code base that makes running Windows executables on Linux distributions possible.

LPub3D is Trevor Sandy's continuation and modernization of Kevin Clague's LDraw building instruction editor. This tool is extremely powerful as it enables the creation of highly detailed, professional looking instructions. It uses external rendering applications to generate the model's step thumbnails to be included in the document. Both LDView and LDGlite are supported.

The latest version can be found as a no-installation-required AppImage at https://github.com/trevorsandy/lpub3d/releases; download LPub3D-<version>-x86_64.AppImage, set it as executable (chmod +x), and double click to open.

LDView

LDView, by Travis Cobbs, is a real-time 3D viewer for displaying LDraw models using hardware-accelerated 3D graphics. It is an essential tool in the creation of a model as it can be used to view and debug, in real-time and with full 3D graphics capacity, the model currently being edited (using the auto-update polling preference). It can also generate snapshots of the displayed content or of specific selected views of the given model. LDView is native to the Linux platform and is readily available for install for both Debian and Red Hat based distributions.

  • Download the latest installer package from LDView's downloads page.
  • Install LDView by using your preferred package manager or command package management tool.

Notes:

APT-based systems (e.g. Ubuntu, Mint): Your system may complain about either missing packages or unresolved dependencies. You may resolve these by running a "fix install" fix like so: $ sudo apt-get -f install

YUM-based systems (e.g. Fedora): LDView's Linux maintainer, Peter Bartfai, has an LDView repository set up using the OpenSuse build server system, from which you can get the latest LDView version, provided you add the yum repository information as follows:

$ sudo cat > /etc/yum.repos.d/ldview.repo << FILE
[ldview]
name=LDView Repository
baseurl=http://download.opensuse.org/repositories/home:/pbartfai/Fedora_$(rpm -E %fedora)/
gpgkey=http://download.opensuse.org/repositories/home:/pbartfai/Fedora_$(rpm -E %fedora)/repodata/repomd.xml.key

  • replacing an old part entry by a newer one
  • replacing a specified color by a different one
  • replacing a specific part's color with a new color

Notes:
