![]() The second number is the color of the line. (In this case it is a straight line with a start and end point). The line types are: 0: Comment or META Command 1: Sub-file reference 2: Line 3: Triangle 4: Quadrilateral 5: Optional Line For example, a line type 2 would might look like: 2 24 -3.75 0 3.75 3.75 0 3.75 The first number is the line type. The line type is set by the first number on each entry. Specifically, there are six general line types in a LDRAW file. It is made up of a series of lines that define the edges and shapes of the object. I thought it would be of benefit to everyone to explore how to develop elements directly in the dat format.Ī dat file is a text file that defines the object. In the past I have designed components in a GUI environment such as SolidWorks, and then coverted the files into a LDRAW format. *There are an awesome set of LDRAW authoring tools at Philippe Hurbain's website: ![]() *Kevin Clague et al LEGO SOFTWARE POWER TOOLS WITH LDRAW, MLCAD AND LPUB There are a number of awesome resources that cover in detail how to use LDRAW and related programs: I have plans for future ft-ibles covering this information. There is a lot more detail that can be added. DISCLAIMER: This is meant as a very bare bones/general introduction to get things rolling. This ft-ible is a basic introduction to how to create your own library of parts for LDRAW. dat file to build a library that can be used to generate awesome CAD images documenting models! A dat file is a text file that defines an object (such as a LEGO brick). It is useful to know how to create an original. There are many unofficial libraries that can work with LDRAW. Analogous programs such as LEOCAD can access the LDRAW libraries. MLCAD is the gui interface that sits on LDRAW. It is easy to use, released under the open content license, and very popular.

This article was published in BrickJournal, Issue 9, Volume 2 Have an insight into how to author patterns for LDraw parts. Having their digital counterparts also available in the LDraw system calls for special authoring techniques. The “Standard Grin Pattern”, the “Classic Space Logo” - some patterns are as iconic as the brick shape itself. Get a crash course in LDraw part authoring and learn that you don’t have to be a math guru or hack your way through a jungle of ones or zeros. Many people build models virtually with editors like MLCad, Leo, SR 3D or Bricksmith but just a handful know how to create a part for these programs to use or what’s needed before a part can show up in the preview window of your preferred building editor. In this category you'll find parts I created by myself or reengineered solely as mock-up. accepts only virtual parts of official LEGO elements. You'll find the helper parts shown in the image as well as high quality 3D-numbers to label your instruction steps directly in a LDraw scene without the usage of photo editing or desktop publishing programs. To show how parts fit into each other, building instruction often make usage of exploded views along with arrows or dotted lines. As soon as I finish a so-called unofficial element I submit it to the LDraw Parts Tracker for certification. Missing some of them when browsing MLCad's parts library tree? Well, the official package and updates include only parts which had undergone a peer review and have been certified. These are all official virtual elements which make part of the LDraw library. In this tutorial you'll get an overview on the differnent screens shown by the AIOI as well as some background information. Use the LDraw All-In-One-Installer, in short AIOI, if you want a quick and easy way to install the LDraw Parts Library and many of the popular 3rd party tools as well.
