Mirror of the Lego Digital Designer 4.3.10 installers + user manual + archive of my own LXF files
LEGO have announced they will finally be killing Lego Digital Designer (LDD), their famous CAD program that allows anyone to build LEGO models on their computer. This doesn't surprise me and I always questioned the future of LDD when they removed Pick-a-Brick which allowed you to order the models you made.
I have great nostalgia for this software and want to preserve a few models I have floating on my Google Drive. EU-based LEGO fan forum Eurobricks has a brilliant thread encouraging users to upload retail models made in LDD, several of these models are from that. I do not own Lego Digital Designer and all rights (to my best knowledge) belong to the LEGO Group.
I also archived the (download page) on archive.today.
LEGO purchased BrickLink and now BrickLink Studio is deemed the successor to LDD. I plan on trying it, particularly when the tagline is "FEEL THE DIFFERENCE".
If you proceed to download and use LDD version 4.3.10 you will experience errors when launching the application. You can still use "offline" mode if you wish.
The official minimum system requirements as taken from the LDD download page. Reportedly high RAM is required for particularly large models.
| Apple Mac | Windows PC | |
|---|---|---|
| OS | macOS 10.10 | Windows XP, Windows Vista, Windows 7, Windows 8 or Windows 10 |
| CPU | Intel processor | 1GHz processor or higher |
| RAM | 1GB | 1GB |
| GPU | NVIDIA GeForce 5200/ATI Radeon 7500 or better | 128MB graphics card (OpenGL 1.1 or higher compatible) |
| HDD | 1GB | 1GB |
Unsurprisingly, LDD 4.3 does not support PowerPC Macs (Apple switched to Intel back in 2006 and now to their own ARM chips in 2020).
