I have LDD on my Mac and have used it to create EV3 models (like an FLL robot, or a Lego dot-matrix printer). Recently, I purchased a cheap Windows laptop for use by a FLL team.

After twice installing LDD v4.3.11 on the PC, however, I am running into a roadblock. It doesn't seem to have EV3-specific parts, such as EV3 motors, sensors, or brick/brain.

For example, if on the PC I try to load a model I designed using LDD on my Mac (which does have these parts), I get the following error:

1 brick could not be loaded and has been removed from the model

If I search the parts either by specific part number or by the term "EV3", I find nothing. It also doesn't matter which mode I use ("Mindstorms", "Extended", etc).

I think they are just missing from v4.3.11 for Windows!

Can anyone confirm? Can anyone suggest a way to get them back?

  • yes i m also facing the same issue in fact EV3 large motor ,medium motor ,and EV3 brick are totally omitted from piece list – user13475 Dec 21 '19 at 18:33

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:

Also found a hint for installing old versions on Windows 10 if Adobe Flash Player fails to install: https://breeks.gr/index.php/el/menu-gr-main-forum/general-discussion-english/183-installing-ldd-on-windows-10.html

For anyone looking for an alternative to LDD since it is not longer supported by LEGO, Studio from Bricklink has a similar building experience and can even open LDD files.

    So it seems I had that 4.3.12 installed (with "Brick version 777"). Downgrading to 4.3.11 (with "Brick version 2670") restored the EV3 parts! – Kirkman14 Sep 19 '19 at 21:44

    For some reason the latest version is missing a lot of parts. I wonder if it might be possible to copy the LIF files from the previous version. – Alexander O'Mara Sep 19 '19 at 23:45
