CAD Tools

There are many useful and practical software tools available to the LEGO® fan community. These tools can be used to build models, plan layouts, illustrate instructions, and much more. In this section, you can find libraries, extensions, data files, etc. specifically related to LEGO® trains for some of these software tools. These resources can be downloaded from the categorized tables below.

BlueBrick Add-on Libraries

BlueBrick (by Alban Nanty) is an excellent open source software tool for designing Lego® based layouts. This tool allows you to arrange baseplates, track, and other items into any desired layout configuration. You can assign different drawing layers for each item, generate parts lists, add text annotations, and much more. BlueBrick comes pre-installed with many different parts libraries, including Lego® track from the 4.5V era up to current 9V/RC track. Since the introduction of new alternative track items from ME Models, we can now build layouts with new curve radii options of 56, 72, 88, and 104 studs. Below, you can download additional component libraries to expand the possibilities of layout design using BlueBrick.

Since v.1.2, the schematic track library has been split into two parts: one for RC/plastic track components and another for 9V/metal track components. This makes each library a more manageable size and the grouping of similar components makes track elements easier to find.

BlueBrick Add-on Libraries

Preview	Description	Rev
	RC Schematic Track Library This library exclusively contains plastic track components illustrated as symbols so that you can create track schematic drawings. This library has the following features: Universal: includes plastic track elements from LEGO®, ME Models, BrickTracks, and other vendors Colour Coded: elements are colour coded for easy identification. Red elements represent track products from LEGO®, orange elements are custom parts, and components have different colours for each unique curve radius. Custom Elements: a range of customized track elements are included such as single element stub switches and compound track arrangements such as pre-made/aligned crossovers (LH/RH) Complete: all track elements are properly identified by colour and part number (where applicable). This will be especially helpful when generating a parts list since it will itemize all unique parts. It is recommended to install this library into a new sub-folder of the BlueBrick ..\parts\ folder. To install and use this library: Make a new subfolder under the BlueBrick library folder, e.g. ..\BlueBrick 1.8.0\parts\Schematic RC Copy and unzip the SchematicRC.zip file into the new sub-folder Launch BlueBrick and verify that the new track components are contained in a new category with the same name as the sub-folder you created, e.g. "Schematic RC"	1.2

	9V Schematic Track Library This library exclusively contains metal/9V track components illustrated as symbols so that you can create track schematic drawings. This library has the following features: Universal: includes metal/9V track elements from LEGO®, ME Models, and other vendors Colour Coded: elements are colour coded for easy identification. Red elements represent track products from LEGO®, orange elements are custom parts, and components have different colours for each unique curve radius. Custom Elements: a range of customized track elements are included such as single element stub switches and compound track arrangements such as pre-made/aligned crossovers (LH/RH) Complete: all track elements are properly identified by colour and part number (where applicable).
