What is U3D file?

U3D extension files belong to the category of graphic files. The content of files with the U3D extension includes three-dimensional models. This standard was developed by a consortium of large enterprises (including Boeing, Intel, and HP) with the goal of standardizing the recording standards of 3D data. In the U3D files, we find all the information concerning three-dimensional models, in particular:

  • dimensions and shapes,
  • textures,
  • rules and methods of lighting,
  • trajectory of motion and rotations.

Files with the U3D extension contain three-dimensional models.

How Are U3D Files Utilized?

U3D extension files are supported by a large number of applications, serving to generate three-dimensional reality. Thanks to the use of CAD applications, U3D files can store 3D models of computer-designed parts, elements, and even entire installations. The U3D format was adopted as an ECMA-363 standard, which contributed to its increased popularity. Nowadays, the fourth edition is widely used as a standard for recording complete information about 3d objects. Files with the U3D extension are supported by so many graphic programs that there is no need to convert this format to others.

Programs which support U3D file extension

Below you will find an index of software programs that can be used to open U3D files divided into 3 categories according to system platform supported. Files with U3D suffix can be copied to any mobile device or system platform, but it may not be possible to open them properly on target system.

How to open file with U3D extension?

There can be multiple causes why you have problems with opening U3D files on given system. Fortunately, most common problems with U3D files can be solved without in-depth IT knowledge, and most importantly, in a matter of minutes. The following is a list of guidelines that will help you identify and solve file-related problems.

Step 1. Download and install Blender

Install software to open U3D file The most common reason for such problems is the lack of proper applications that supports U3D files installed on the system. This one is an easy one. Select Blender or one of the recommended programs (for example, Adobe Acrobat, Adobe Photoshop, Micro Poser) and download it from appropriate source and install on your system. The full list of programs grouped by operating systems can be found above. If you want to download Blender installer in the most secured manner, we suggest you visit Stichting Blender Foundation website and download from their official repositories.

Step 2. Verify the you have the latest version of Blender

Update software that support file extension U3DIf you already have Blender installed on your systems and U3D files are still not opened properly, check if you have the latest version of the software. It may also happen that software creators by updating their applications add compatibility with other, newer file formats. The reason that Blender cannot handle files with U3D may be that the software is outdated. The latest version of Blender should support all file formats that where compatible with older versions of the software.

Step 3. Set the default application to open U3D files to Blender

If you have the latest version of Blender installed and the problem persists, select it as the default program to be used to manage U3D on your device. The method is quite simple and varies little across operating systems.

Associate software with U3D file on Windows

Change the default application in Windows

  • Choose the Open with entry from the file menu accessed by right-mouse clicking on the U3D file
  • Click Choose another app and then select More apps option
  • Finally select Look for another app on this PC, point to the folder where Blender is installed, check the Always use this app to open U3D files box and conform your selection by clicking OK button
Associate software with U3D file on Mac

Change the default application in Mac OS

  • Right-click the U3D file and select Information
  • Proceed to the Open with section. If its closed, click the title to access available options
  • Select Blender and click Change for all...
  • Finally, a This change will be applied to all files with U3D extension message should pop-up. Click Continue button in order to confirm your choice.

Step 4. Verify that the U3D is not faulty

You closely followed the steps listed in points 1-3, but the problem is still present? You should check whether the file is a proper U3D file. It is probable that the file is corrupted and thus cannot be accessed.

Check U3D file for viruses
1. Check the U3D file for viruses or malware

If the U3D is indeed infected, it is possible that the malware is blocking it from opening. It is advised to scan the system for viruses and malware as soon as possible or use an online antivirus scanner. If the U3D file is indeed infected follow the instructions below.

2. Verify that the U3D file’s structure is intact

Did you receive the U3D file in question from a different person? Ask him/her to send it one more time. It is possible that the file has not been properly copied to a data storage and is incomplete and therefore cannot be opened. It could happen the the download process of file with U3D extension was interrupted and the file data is defective. Download the file again from the same source.

3. Verify whether your account has administrative rights

Sometimes in order to access files user need to have administrative privileges. Switch to an account that has required privileges and try opening the Universal 3D Format file again.

4. Verify that your device fulfills the requirements to be able to open Blender

If the systems has insufficient resources to open U3D files, try closing all currently running applications and try again.

5. Verify that your operating system and drivers are up to date

Latest versions of programs and drivers may help you solve problems with Universal 3D Format files and ensure security of your device and operating system. It may be the case that the U3D files work properly with updated software that addresses some system bugs.
