What is an M3D file?

M3D files mostly belong to DIALux by DIAL. M3D is a file extension that's mainly used to store 3D furniture objects and their preview images created using DIALux, a Windows-based software for light planning. 3D objects in such M3D files include furniture, scenes, and characters. M3D files can also be used to import and export 3D objects. Earlier editions of Corel Motion 3D also used the M3D file format to store 3D scenes. In addition, M3D is used as a file extension for EverQuest game data files. An older use case of M3D file extension can be found in Cossacks, a real-time strategy game that stored single-player map data in M3D files.

How to open M3D files

You need a suitable software like DIALux to open an M3D file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your M3D file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a M3D file directly in the browser:. Just drag the file onto this browser window and drop it.

M3D file format:

To find out what program is needed to open M3D files, you need to determine the file format. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So you need a detailed analysis of a file to find out the format and the associated program. Below you will find our evaluation of the M3D files:

The M3D file extension is quite widespread and includes different formats for different programs. The file formats most commonly found in M3D files are:

60% of all M3D files are based on the zip format, the M3D file contains a number of compressed files. Primarily 5 to 7 files are included. Customary file names are Contents, FileInfo, MetaInfo, MetaProductInfo, Preview, Sources and SysInfo. A little tip: If you rename the file extension to .zip and then double-click, you will see the included files and images. The file size is in the range of 60 KB to 2 MB. The keywords FileInfo, [FileInfo], AppName and AppVersion=KOMPAS_ are typical for these files. Such files sometimes refer to detal, holder, korpus, model, cover, setup, case, drawing, housing, virtual, flange, shaft and step.
10% of all M3D files belong to Kompas-3D Model. They consist of unreadable binary data. The files are often between 86 KB and 1 MB in size. Several words can almost always be found in the files, e.g. DbQ8, DOCUMENT_IMAGE and HdR9$. Such files sometimes refer to side and driver.

All the rest of the M3D files (30%) have different formats, the following 14 formats exist: DIALux 3D Mesh / furniture, Model 3D, EXE, XML, Mad, MFSBCFS and File. Sometimes used for mssa, mssds, msseax, mssrsx, mssdx, mssfast or msssoft. If you want to find out which format your M3D file belongs to, just click on the button "Choose your .m3d file to analyze".

How to solve problems with M3D files

Associate the M3D file extension with the correct application.
Update your software that should actually open 3d furniture objects. Because only the current version supports the latest M3D file format. Search, therefore, e.g. on the DIAL manufacturer website after an available DIALux update.
To make sure that your M3D file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
