Our free and fast tool will convert most 3D mesh or 3DM (Rhinoceros 3D) model files to a standard IDTF (PDF With integrated 3D Models) 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 IDTF file and will ready for download shortly afterwards. For more information about the 3DM to IDTF conversion process see the conversion information section below for more information.
Here are 2 simple steps to convert your 3DM to IDTF.
First click the "Upload..." button, select your 3DM file to upload. Select any configuration options. When the 3DM to IDTF conversion has completed, you can download your IDTF file straight away.
We aim to process all 3DM to IDTF conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
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.
Yes, of course! We do not store the 3DM file you submit to us. The resulting IDTF file, once created is deleted 15 minutes after upload and the download link will expire after this time.
Yes! Our 3DM to IDTF tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
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.
Yes! Our 3DM tool supports full batch conversions. You can upload up to 25 3DM files at a time. Our tool will convert them all as quickly as possible. Once completed, you can either download the IDTF files individually or download them all in a single ZIP file.
Converting from the 3DM file format to IDTF 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 IDTF 3D model. Lets start with the conversion process, which involves the following steps:
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.
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 ready for exporting to the IDTF 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 this to the IDTF format.

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 mathematically precision compared to triangle/polygon based mesh geometry formats such as STL. Along with support for converting between other CAD formats the 3DM format can also supports two different scripting languages.
If your 3DM file contains textures, these will be ignored. If a material contains color information this will be translated where possible.
The IDTF file format is a bespoke format that enables interactive 3D content to be embedded within a PDF document. Currently only Adobe Reader and PDF-XChange Editor are able to render PDF documents that contain this 3D content.
IDTF files are a simple text-based format containing 3D geometry defined using vertices and faces in a structured hierarchy. Prior to importing the IDTF file to the PDF it must be converted to a U3D file format using one of the free applications such as IDTFConverter.
Currently only mesh geometry will be carried over from your source model to the final IDTF file for download.
