About SR3D Builder modeling software

I have been using SR3D Builder to create my digital models after finish my real models from more than 5 years.

I use it because in my opinion it is the best software to create technic models. You can do more things and it has more parts than LDD, and it is easier, more intuitive and quicker to build than MLCad.

Also its 3D models files are compatible with all LDraw tools(MLCad, LDview, etc).

But unfortunately, Sergio Reano, the creator of this awesome program passed away in October 2014.

But today is not possible download the progran fron its official site(HERE).

Quick guide about how to install lastest SR3D in your PC (Windows 7 o newer)

I have uploaded the lastest free available version(, you can download it HERE.

SR3D uses a very particular software and windows functions to run in and it is hard to get it running correctly.

Usually when try to install SR3D in your PC the installation finish correctly without any advise.

But when you try to execute the program and error message window appears and you can't use it.

I bought a new PC a few months ago and I spend more than 6 hours to find a solution to get the SR3D work properly. I downloaded the newest drivers for all PC devices, newest DirectX, all Windows updates, trying with older SR3D versions, anything you can imagine and nothing worked.

But finally I found a very easy solution for this problem. Actually I don't know why it works, but it does.

This solution worked for in two differents PC, so I hope it work for you too if you can't get the SR3D run correctly.

1 - Uninstall any version of SR3D and LDraw you have in your PC.

2 - Download the lastest version of LDraw All-in-One which included SR3D Builder, it was the 2013_1_v1 version. You can download it HERE

3 - Instant LDraw software tools including at least MLCad, LDraw and SR3D Builder ( version), I recomend install all tools because they need just a few MB in your HDD.

4 - When the LDraw installation end open SR3D, and finish the instalation (rebuild part list).

5 - When SR3D finish it must work properly with all its functions, but it is not in the lastest version.
Then you can keep in that version if you want, or upgrade it.

6 - To upgrade it just close SR3D and install the lastest version ( normaly. When the instalation finish it should work properly.

Now if you want you can upgrade LDraw if you want to any version you wish.

I hope this short guide can help you.

Hi, Sheepo. Thank you for sharing. Is the software working in Mac?

No, it is only for Windows. But many Ldraw tools work in MAC

Please, could you tell me what are the best tutorials on SR 3dBuilder.

Sheepo said...

Try with the official SR3D website.

Pops said...

Thank you! but it seems that all content in the "User Manuals" section of official SR3D website was deleted..."URL not found". That's why I asked you if you knew other sources.

Thanks Sheepo. Sad to hear about Sergio's passing. He and I had emailed back and forth about SR3D a few years ago.

Does anyone have a copy of the user manual? When I drag parts around, they snap to things and I can figure out how to rotate and shift them. They seem to only snap to other blocks.

Hello, i made the install twice as you write, but when started the program, have an error:

The file ZSTUD.DAT contain an error: probably TAB character instead of space or there is a missed zero '0' before a dot '.'.
The line containing the error is: 4 16 -4 0 -1.5 -4 -4 1.5 -4 0 1.5
SR 3D Builder will terminate

I close sr3d with only task manager.
In the sr3d folder and in the ldraw folder zstud.dat files not contains this line...

What is the problem? (win10/64bit)
