Convert Your 3D Mesh/Model 3DM Files to BLEND

to

Our free and fast tool will convert most 3D mesh or 3DM (Rhinoceros 3D) model files to a standard BLEND (Blender) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple 3DM files; up to 25 files at a time can be converted.

To convert your 3DM file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a BLEND file and will be ready for download shortly afterwards. For more information about the 3DM to BLEND conversion process, see the conversion information section below.

Frequently Asked Questions

How can I convert my 3DM file to BLEND?

First click the "Upload..." button, select your 3DM file to upload. Select any configuration options. When the 3DM to BLEND conversion has completed, you can download your BLEND file straight away.

How long does it take to convert my 3DM to BLEND?

We aim to process all 3DM to BLEND conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the 3DM to BLEND conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.

Is it safe to convert my 3DM to BLEND on ImageToStl.com?

Yes, of course! We do not store the 3DM file you submit to us. The resulting BLEND file, once created is deleted 15 minutes after upload and the download link will expire after this time.

Can I convert 3DM to BLEND on Windows, Linux, Android, iOS or Mac OS?

Yes! Our 3DM to BLEND tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

What if I am using an Ad Blocker, will that affect things?

Yes. Although you can use an Ad Blocker, if you like our 3DM conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.

What version of Blender will the file be saved as?

Our tool will save all Blender files that can be opened with version 4.0 of Blender.

I have several 3DM files; can I batch convert my 3DM to BLEND?

Yes! Our 3DM tool supports full batch conversions. You can upload up to 25 and 3DM files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the BLEND files individually or download them all in a single ZIP file.

Description

The 3DM format, also known as Rhino3D or Rhinoceros 3D, is a 3D graphics model file format developed and used in CAD applications, industrial design, and 3D printing. The format has some compatibility with Adobe Illustrator and can be exported as an AI file using vector graphics.

Although it is a 3D file format, it stores data in the NURBS geometry format, which allows for greater mathematical precision compared to triangle or polygon-based mesh geometry formats such as STL. Along with support for converting between other CAD formats, the 3DM format can also support two different scripting languages.

3DM Notes

If your 3DM file contains textures, these will be ignored. If a material contains color information, this will be translated where possible.

Supported Features

  • Mesh geometry
  • Mesh material colors

Unsupported Features

Description

The BLEND file type is the native 3D graphics file format of the 3D modeling application Blender. Originally released in 1994, Blender has grown over the years and is one of the most popular 3D applications available.

BLEND files store 3D content such as 3D geometry, vertices, faces, normals, animations, materials, and much more. Blender is free and open-source, contains many features you would expect in a high-end 3D editing application, and is available for most current operating systems.

BLEND Notes

If your original model file contains texture images and other texture-related data, these will be included in the final BLEND file.

Supported Features

  • Mesh geometry
  • Materials
  • Textures

How does it work?

Converting from the 3DM file format to BLEND can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your 3DM file to a valid BLEND 3D model. Let's start with the conversion process, which involves the following steps:

Step 1: Read the Source 3DM File

In its simplest form, an 3DM file is a binary data file containing 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.

For more information regarding the 3DM file format, please see this great article that goes into a lot of detail explaining the 3DM format.

Step 2: Process File Data

With the 3DM file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the BLEND format.

Step 3: Saving to the BLEND Format

With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the BLEND format.
