Open 3DM File

A .3DM file is a Rhinoceros 3D model file, used by a variety of 3D modeling, CAD (computer-aided design), and animation software programs. Typically 3DM files are created by Rhinoceros 3D modeling software. It is a file that contains information about the geometry, materials, and other properties of a 3D model, and can be used to store and exchange 3D models between different programs or platforms.

3DM and NURBS

3DM is frequently used to exchange NURBS geometry.

NURBS (Non-Uniform Rational B-Splines) are a type of curve or surface used in 3D modeling and computer graphics to represent smooth, mathematically defined shapes. In a .3DM file, NURBS curves and surfaces can be used to represent the geometry of a 3D model, allowing the model to have smooth, curved shapes and surfaces.

In a .3DM file, NURBS curves and surfaces are stored as a series of control points and curve or surface data, which define the shape and properties of the NURBS curve or surface. This data can be used by software programs to accurately render and display the NURBS curve or surface, allowing the 3D model to have smooth, detailed shapes and surfaces.

NURBS are often used in 3D modeling and computer graphics because they allow for the creation of complex, smooth shapes that are difficult to represent using other types of curves or surfaces. They are particularly useful for modeling organic shapes, such as those found in nature, and are often used in the design and visualization of products, buildings, and other objects.

In a .3DM file, NURBS curves and surfaces can be used in combination with other types of geometry, such as polygonal meshes and splines, to create a more detailed and accurate representation of a 3D model. They can also be used to create smooth, curved surfaces and shapes that would be difficult to model using other types of geometry.

Software to open 3DM file

How Can I Open 3DM File on Windows

We researched and learned that the best way to open 3DM file is to find a 3DM file in question in Windows OS File Explorer and double click on it to launch the corresponding application.
If a 3DM file is not opened in an application and you instead get a "Windows can't open a file" error message you should try looking for an application which can open the file in question.
If you know the application which can open 3DM file then run it and see if there is a File->Open main menu option in the application.
If you don't know the application which function as 3DM file opener then try to search online for "3DM viewer", "application to open 3DM file" or "open 3DM file" queries in the search engine you like.
Install the application you found and check if it can open 3DM file

How Can I Open 3DM File on Mac OS

We recommend to find a 3DM file in question in Mac OS Finder and double click on it to launch the corresponding application.
If a 3DM file is not opened in a Mac OS application and you instead get a "There is no application set to open the file" error message you can click on "Search App Store" in the error dialog and Mac OS will show you applications compatible with 3DM file.
If you know the Mac OS application which can work as 3DM file opener you can choose the "Choose Application..." option in the error box to associate the file extension and open 3DM file in it.
If you don't know the application which can open 3DM file then try to search for "3DM viewer", "application to open 3DM file" or "read 3DM file" queries in the online search engine you like.
Install the application you found and check if it can read 3DM file

How Can I Open 3DM File on Android

If you downloaded a 3DM file on Android device you can open it by following steps below:

In the Android apps list on your Android device find "My Files" or "File manager" app and tap to start it.
Tap on "Downloads" folder inside the app.
You should see your downloaded 3DM file in that folder.
Tap on the file. If Android device supports opening the file you downloaded it will open in the corresponding app.
If file does not open you can look for the corresponding app that can open the file by searching Android App Store for the "3DM".
If you cannot open the file with the apps from Android App Store it is possible that the file could only be opened on desktop platforms such as Windows or Mac OS. Try searching for "3DM viewer", "3DM file reader" online and see if any desktop applications can open it.
It is also possible that the file you downloaded is outdated and is no longer supported.

How to Open 3DM File on iPhone or iPad

To open 3DM File on iOS device follow steps below:

We advies to open Files app on your iPhone or iPad device. You can find it by swiping down on the home screen and typing "Files" in the search bar.
Tap on the Downloads folder on the Files app home screen.
You will see all files that you recently downloaded. Tap on the 3DM file to view it.
If you have the right app that can open it it will automatically launch and open your file.
If you don't have the app which can open it you need to serch Apple app store for "3DM". This way you can find apps which can open 3DM files.
If this doesn't help it is possible that your file could be opened only by the desktop application. To find an app which can open it on desktop look for "3DM viewer" or "3DM file" online in your favorite search engine.
