Installation advice for the LDraw Parts Library and MLCad

 
 
 
     
  This tutorial will teach you how to set up manually a simple LDraw system with the MLCad editor and the LDraw Parts Library. Furthermore it will show you tips and tricks and help with troubleshooting problems you might encounter. The tutorial is based on the LDraw Parts Library 2008-01 and MLCad 3.3.

Follow this tutorial ONLY if the LDraw All-In-One-Installer has failed or won't run on your OS. This is most true if you are still using Windows 95, 98, ME, NT Ver 4, 2000, or XP below SP2.

Navigate to the Download pages at LDraw.org and download the following file under the heading Core Files and Libraries:

Download icon   LDraw Parts Library (Windows)

Go also to MLCad's home page and download the file named:

Download icon   mlcad330.zip

The tutorial assumes that both files LDrawparts.exe and mlcad330.zip have been downloaded to your hard disk. The tutorial is grouped in two sections:

Installing the LDraw parts library

 
     
  The LDraw parts library is a collection of LDraw-format CAD files representing many of LEGO bricks produced. The parts library is required to use any of the LDraw CAD programs such as MLCad, LPUb or LDView.

  1. First we are going to install the LDraw Parts Library. Either double click the executable LDrawParts.exe setup file or select Open from the contextual menu. This pops up a dialogue asking for your preferred language. Select English from the drop down box and confirm you choice by hitting the OK button. Brick 1x2

  2. There haven't yet been any compatibility problems reported with other applications (including programs of the LDraw System of Tools) running while installing the library; nonetheless it is a good idea to follow this recommendation. Click the Next > button and proceed to the next dialogue only AFTER you have saved your work and closed all open programs.

  3. Read the License Agreement for the LDraw Parts Library by scrolling down and understand the legal terms of the license. After installation you can find the Legal Code (CAlicense.txt) as well as the easy-reading text shown in the above dialogue (CAreadme.txt) in the library's root folder or on the LDraw.org web site. An addition you'll find some rules (NonCAreadme.txt) which governs so-called NonCA-Parts.  
  4. After reading and agreeing with the license select I accept the agreement to proceed with the installation or press Cancel to abandon the setup.  
  5. The Next > button will only become accessible after you've agreed to the license terms. Click Next > and go to the next screen.

  6. It is recommended that you install the library in the proposed C:\Programs\LDraw folder. Change the location only if you're an experienced user.

NOTE! On 64 bit operating systems install to C:\Program files (x86)\LDraw.
 
  7. Click the Next > button and proceed to the next dialog.

  8. The type of installation chosen from the drop down box allows you to install the following segments of the official LDraw library.  
       
   
Core parts library The library of officially released parts for which the authors have agreed to the Contributor Agreement, allowing their work to be re-distributed. Full details of this agreement can be found in the CAreadme.txt and CAlicense.txt files in the same folder as this file. This download is restricted to generic colour versions of each part and does not contain duplicate copies of part files where different numbers have been used for the same physical part. This library may be re-distributed, subject to the conditions laid out in CAreadme.txt.
Alias parts library The library of officially released part aliases. This includes generic colour versions of parts that are physically identical to parts in the core parts library, but have a different part numbers, either because of production differences between opaque and transparent parts or due to evolution of the part numbering scheme.
Physical colour parts library The library of officially released physical colour parts. This includes hard-coded colour versions of parts or composite parts.
Non re-distributable parts library The library of officially released parts for which the authors have not agreed to the Contributor Agreement, or where we have been unable to contact the original author. This download is restricted to generic colour versions of each part and does not contain duplicate copies of part files where different numbers have been used for the same physical part. This library MAY NOT be re-distributed, as detailed in the conditions laid out in NonCAreadme.txt file.
