Here we detail how to convert your U3D file to an DAE file using the export options found within the SolidWorks application. Currently, our converters cannot convert directly from U3D to DAE. However, using the built-in export functions of SolidWorks, we can achieve the conversion.
Firstly, you will need to load your U3D file into SolidWorks and select the export to STEP option. Once you have your file in the STEP format, you can use our STEP to DAE converter to complete the conversion process.
Here are two simple steps to convert your U3D to DAE.
| Extension | U3D |
| Full Name | Universal 3D |
| Type | 3D Model |
| Mime Type | model/u3d |
| Format | Binary |
| Tools | U3D Converters, 3D Model Voxelizer, Create U3D Animation |
The U3D file is a 3D file format (Universal 3D) developed by a consortium of well-known companies in 2005 with the idea of creating a standardized file format for storing 3D data, including mesh vertices, textures, bones, and effects.
U3D files are binary in nature, containing a block-based structure that, following later revisions, could be extended with custom blocks.
| Extension | DAE |
| Full Name | COLLADA - Collaborative Design Activity |
| Type | 3D Model |
| Mime Type | text/xml |
| Format | Text |
| Tools | DAE Converters, 3D Model Voxelizer, Create DAE Animation, DAE Asset Extractor, Text to DAE, DAE Viewer |
| Open With | Blender, MeshLab |
The DAE format (also known as COLLADA) is a 3D file format used to describe 3D models, meshes, and 3D worlds using a simple text-based structure. The format was introduced in 2004 by Sony Computer Entertainment and is currently managed by the Khronos Group.
DAE files are a text/XML-based file format containing 3D geometric information used to describe 3D objects and meshes such as vertices, faces, animations, materials, camera/lighting elements, and other related metadata. The format has widespread usage and support, with applications such as Blender and MeshLab being able to read and write to it.
Our tool will save any texture files separately; these additional files will be included with your final DAE file at the time of download.
Converting from the U3D file format to DAE 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 U3D file to a valid DAE 3D model. Let's start with the conversion process, which involves the following steps:
In its simplest form, an U3D 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 U3D file format, please see this great article that goes into a lot of detail explaining the U3D format.
With the U3D 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 DAE 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 DAE format.
We aim to process all U3D to DAE conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
Yes! If your U3D file contains textured geometry, the texture image files along with the texture coordinates (UV data) will be exported with the final DAE file.
Yes, of course! We do not store the U3D file you submit to us. The resulting DAE file, once created is deleted 15 minutes after upload and the download link will expire after this time.
No. All our conversion tools process your U3D file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted DAE file quickly.
Yes! Our U3D to DAE 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 U3D 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. When you have converted your U3D to DAE, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
