What is a 3DM file?

File with a .3DM extension contains a 3D model consisting of information on surfaces, curves and points stored in an open format utilising both data representations in NURBS nets and polygons. On the www.Opennurbs.org website, a library supporting the 3DM format can be found.

3DM storing is native within the CAD/CAM/CAE Rhinoceros 3D software. Program currently available in the Rhino 6 version has a wide range of applications in modelling and creating 3D projects used in industry, manufacturing and also interactive animations and games.

How to open 3DM files

If you cannot open the 3DM file on your computer - there may be several reasons. The first and most important reason (the most common) is the lack of a suitable software that supports 3DM among those that are installed on your device.

A very simple way to solve this problem is to find and download the appropriate application. The first part of the task has already been done – the software supporting the 3DM file can be found in the table. Now just download and install the appropriate application.

Possible problems with the 3DM format files

The inability to open and operate the 3DM file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the 3DML Data Format file. Below is a list of possible problems.

  • Corruption of a 3DM file which is being opened
  • Incorrect links to the 3DM file in registry entries.
  • Accidental deletion of the description of the 3DM from the Windows registry
  • Incomplete installation of an application that supports the 3DM format
  • The 3DM file which is being opened is infected with an undesirable malware.
  • The computer does not have enough hardware resources to cope with the opening of the 3DM file.
  • Drivers of equipment used by the computer to open a 3DM file are out of date.

If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the 3DM file should operate with your programs without any problem. If the problem with the 3DM file has not been solved, it may be due to the fact that in this case there is also another rare problem with the 3DM file. In this case, the only you can do is to ask for assistance of a professional staff.

How to associate the file with an installed software?

If you want to associate a file with a new program (e.g. my-file.3DM) you have two ways to do it. The first and the easiest one is to right-click on the selected 3DM file. From the drop-down menu select "Choose default program", then click "Browse" and find the desired program. The whole operation must be confirmed by clicking OK. The second and more difficult to do is associate the 3DM file extension to the corresponding software in the Windows Registry.

Is there one way to open unknown files?

Many files contain only simple text data. It is possible that while opening unknown files (e.g. 3DM) with a simple text editor like Windows Notepad will allow us to see some of the data encoded in the file. This method allows you to preview the contents of many files, but probably not in such a structure as a program dedicated to support them.
