I found a few ways to convert a 3D model into a Lego sculpture. The first is a program called Dolphin Brickr. It works very well, as you can see in this image of Yoshi: The downside to this program is that it only runs on Macs, This runs on both Windows and Macs now and the output format is a series of images, one for each layer. So you can't import it into ...

(fair warning: I work for a 3D printer company [Type A Machines]) I thought this cross-posting up on the RepRap forum would be useful here. Summarizing that post: It is possible to 3D print LEGO-compatible parts on desktop 3D printers, but with caveats: The fit will likely never be as tight as real LEGOs. Those are tough tolerances to match. LEGO Corp ...

The Lego Movie Complete B-ROLL (2014) footage briefly shows that the animator is using Autodesk Softimage 2012 (at about 8:57) to move the limbs of a digital minifigure. 10 minutes in to the video we can see an animator going through frame-by-frame a partially rendered draft of a scene from the movie. The animator has the ability to draw and possibly ...

The sign-in is to enable cloud saves, build with friends, wanted list export, upload to the Studio Gallery, shopping integration features like price lookup, and probably some other features I haven't thought of or have not been mentioned in the comments yet. If you don't plan on using any of those features then it isn't required to sign-in.

Yes, there is LXFML - which is if you like an "offical" XML format for LEGO models - in that it's produced and maintained by The LEGO Group. The .LXF format used by LEGO Digital Designer is a compressed archive containing a thumbnail in .png format and a model definition file in LFXML. As I noted in the answer to that question, the LDD team have shared ...

The most commonly used one is Lego Digital Designer (often called LDD). This has the advantage of being free and quite easy to use, including automatically snapping connections together. However, it is only available for Windows and Mac. Also, LEGO has discontinued support for it. There is a system of programs based on LDraw. These programs tend to be ...

When discussing Animal Logic's involvement in the film, they state: Initially, Production Designer Grant Freckelton and his team utilised LEGO Digital Designer [...]. This allowed everyone, including the Animal Logic art department, to mock up highly accurate LEGO models from which they could calculate the required bricks and build them as subdivision ...

Buy a USB to Serial adapter. There are USB IR Towers, but the drivers are only for older version of Windows. A new USB/Serial adapter, on the other hand, should be compatible with Windows 10 (Windows 10 requires signed drivers, so do your homework before buying). Use 3rd party software. For example, Brickx Command Center and leJOS are compatible with RCX and ...

I was able to integrate this into a research project applying context free grammars: This is not a polished software package, and the design is a bit esoteric given that I started with the goal of applying context free grammars to a practical problem. Hopefully there's something in there that may be useful to someone. :)

Since there doesn't seem to be a tool, I've written my own one. In case anyone else want to use it, check it out here: https://github.com/ChrZae/bricklink-xml-diff Take care tho, it can only really process the XML generated by Stud.io, the XML-format itself has more fields which I didn't care about (also no guarantees it will always work correctly).

You can use Brickify for that. You just upload an STL file and it is converted to LEGO bricks. You don't need the 3D printing part and can go ahead to download the building instructions.

I think I might have a more elegant solution rather than downgrading to LDD 4.3.11 : You just need to replace "Assets.lif" file in the 4.3.12 installation folder with the same file from 4.3.11 version. I happen to have this file archived here. After you replace the file and restart LDD, all bricks will be available and all your previous creations will open ...

LEGO officially stopped supporting NXT in 2015, however, as of 2019, the original NXT programming software is still available on the official LEGO MINDSTORMS web page. The original NXT programming software and EV3 desktop programming software are both 32-bit, so cannot run on macOS 10.15 or later. The new EV3 programming software based on Scratch does not ...

A popular alternative is stud.io, provided by Bricklink. Another possibility mentioned by Alex in the comments is LDCad.

Stud.io only has a small selection of printed parts, but there is hope. Stud.io’s Part Designer tool can help you with your clown torso. Here’s how: Using a paint tool (like Windows’ Paint3D), save only the center bit of the torso to a PNG file, using the above torso image as your master. Open up Part Designer and choose the option to modify a part. Search ...

If the ultrasonic cannot echo-locate the objects because they're too small, even with the sensor suspended very close to the floor, I suggest using a very sensitive feeler out front. It can be sticking forward like a jousting lance, and your robot can swivel back & forth while traveling to scan. The trick to making it very sensitive is to: (1) make it ...

Update: LEGO Education software is now available for free. https://education.lego.com/en-us/downloads/mindstorms-ev3 Original answer: You need to purchase the EV3 Education version of the software.

I've recently upgraded to OS X 10.11 El Capitan (as a matter of fact, I have the exact same model of computer). I've done some basic tests with the EV3 software without running into any issues. I've downloaded programs to the brick using both USB and Bluetooth. Base on past experience with OS upgrades with both the NXT and EV3 software, the problems have ...

rpf stands for "rudolph program file" [source] (I believe "Rudolf" is the internal code name for EV3.) These are the files created using the "Brick Program" utility on the EV3 brick. Once you have created a program on the brick, you can upload the file using the EV3 desktop software. You can find the files in the BrickProg_Save folder. However, after ...

Quoting from Lego's LDD page: Sorry. We don’t support LDD version 4.3.10 anymore. If you still use version 4.3.10 you will experience errors when launching the application. You can still use “offline” mode if you wish. We urge you to update, use the download link, and install free application for Windows PC & Mac OSX. There is nothing wrong with your ...

The current download link at https://www.lego.com/en-us/ldd is https://www.lego.com/assets/franchisesites/ldd/installer/setupldd-pc-4_3_12.exe. When installed it still shows the version as 4.3.11 even though the file name hints that it is 4.3.12. This version is missing EV3 parts. Here are some links for previous versions: UPDATE May 2020: These links are ...

In the comments you asked, ...do you know if it is possible also to work in stud.io with other 3d-files or only with bricks that are pre-integrated? So if i would have designed new bricks could i use them too?... Looks like Brinklink also offers a tweak program to make custom bricks called PartDesigner, that's able to export right into Stud.io.

I believe that the last version that had a complete set of elements was 4.3.11, however that has dependencies on Adobe Flash, so will likely not work on most modern systems that have now removed Flash. The last release, 4.3.12 has a known issue with missing parts. However you can use the parts library (Assets.lif) from 4.3.11 with 4.3.12 - this can be ...

As Zhaph - Ben Duguid said, there is the .LXFML format which is basically an XML document detailing a LEGO model. Another format you might find of use if the .ldr format. .ldr files are used in various LEGO virtual building programs that make up what's called the LDraw system of tools. As an example of the .ldr format, this: Can be generated by pasting this ...

The NXT actually uses IEEE 794 32-bit floating point number format in little endian byte order. I like using this site for conversions.

The simplest way to "remember" a starting position is to make the starting position 0. You can do this using Rest in the Motor Rotation block (1). After your motors have moved (simulated by (2)), you can use a loop (3) to run the motors back to zero. The basic idea though is that if the motor position is negative, then we need to run the motor in the ...
