How to Download and Use Lego Digital Designer V4.1.7 on Your Computer
Lego Digital Designer (LDD) is a free software that lets you create models with virtual Lego bricks. You can use it to design anything you can imagine, from cars to robots, and get parts lists and building instructions for your creations. In this article, we will show you how to download and use LDD V4.1.7 on your computer.
Step 1: Download LDD V4.1.7
To download LDD V4.1.7, you need to visit the official website of BrickLink, a platform for buying and selling Lego parts and sets. BrickLink acquired LDD from Lego in 2019 and has been maintaining and updating it since then. You can find the download link for LDD V4.1.7 here[^1^]. You can choose between Windows or Mac versions, depending on your operating system.
Step 2: Install LDD V4.1.7
After downloading the setup file, you need to run it and follow the instructions to install LDD V4.1.7 on your computer. The installation process is simple and straightforward, and it should not take more than a few minutes. Once the installation is complete, you can launch LDD from your desktop or start menu.
Step 3: Choose a Mode
When you open LDD for the first time, you will see a welcome screen that gives you access to three modes: Lego Digital Designer, Lego Mindstorms, and Lego Digital Designer Extended[^2^]. The Lego Digital Designer mode lets you build your model using a limited selection of bricks and colors, while the Lego Digital Designer Extended mode offers an unlimited collection of bricks and colors. The Lego Mindstorms mode lets you build programmable robots using Lego Mindstorms and Technic elements.
You can choose any mode you like, depending on what kind of model you want to create. You can also switch between modes at any time by clicking on the mode icon at the top left corner of the screen.
Step 4: Build Your Model
Once you have chosen a mode, you can start building your model using the virtual Lego bricks and pieces available in the palette on the left side of the screen. You can drag and drop them onto the building area in the center of the screen, and use the mouse wheel or the arrow keys to rotate them. You can also use the tools at the top of the screen to move, copy, delete, group, or connect bricks.
You can zoom in or out of your model by using the slider at the bottom right corner of the screen, or by pressing the + or - keys on your keyboard. You can also change the view angle of your model by clicking and dragging on the background around your model, or by pressing the A, S, D, or W keys on your keyboard.
Step 5: Save Your Model
When you are happy with your model, you can save it by clicking on the save icon at the top right corner of the screen, or by pressing Ctrl+S on your keyboard. You can name your model and choose a folder to save it in. Your model will be saved as a .lxf file, which is a proprietary format that can only be opened by LDD or BrickLink Studio[^3^], another software for designing Lego models.
Step 6: Export Your Model
If you want to share your model with others, or use it for other purposes, you can export it by clicking on the export icon at the top right corner of the screen, or by pressing Ctrl+E on your keyboard. You can choose between three options: Building Guide Mode (HTML), Image (PNG), or 3D (LDraw). The Building Guide Mode option will generate a .html file that contains step-by-step instructions for building your model in real life. The Image option will generate a .png file that contains a screenshot of your model from different angles. The 3D option will generate a .ldr file that contains a 3D representation of your model that can be opened by other programs that support LDraw format[^4^], such as MLCad or LeoCAD.
