Detailed Description for the .3dm File Extension

.3dm File Extension – An Overview

Three different file types are known to be associated with the .3dm file extension. A brief description of these three file types is shared below:

File Type #1 – Rhino 3D Model File

The .3dm file extension is associated with ‘Rhino 3D’, which is a commercial NURBS-based 3D modeling tool for Windows from Robert McNeel & Associates. Rhino 3D software is primarily used in industrial and multimedia CAD design.

The Rhino 3D Model (.3dm file) comes under the category of 3d Image Files.

  • 3DM Import for Alibre Design

File Type #2 – QuickDraw 3D Metafile

The file extension .3dm is also used by QuickDraw. The mime type is x-world/x-3dmf.

Little information is available on this file type, its purpose or behavior.

File Type #3 – Cadent 3D Model file

The .3dm file extension is also used by Cadent applications. Again, little is known about this file type, its purpose or behavior.

Question: I’ve received a .3dm file as an email attachment, but the file doesn’t open when I double-click it. What can I do?

Answer: In Windows, the easiest way to open a file is to double-click on it. However, in case you don’t have the software that opens the file type, then the file will not open and you are likely to receive an error.

So, if you are unable to open a .3dm file type, it is likely that the required software is not installed on your computer. To view the contents of the file, you may use a reliable file opener program.
