Question: What is an U3D File?

Have you found, downloaded or received an U3D file, but don't know which software program is required to open it?

Before attempting to open an U3D file, you'll need to determine what kind of file you are dealing with and whether it is even possible to open or view the file format.

Answer: Files which are given the .U3D extension are known as Universal 3D files, however other file types may also use this extension. If you are aware of any additional file formats that use the U3D extension, please let us know.

How to open a U3D file:

The best way to open an U3D image file is to simply double-click it and let the default assoisated application open the file. If you are unable to open the file this way, it may be because you do not have the correct application associated with the extension to view or edit the U3D file.

This image file format was added to our database by a visitor to this site, but no additional information was provided. We have yet to investigate this file type further, or there was not enough information available at the time to report accurately on the format.

Please check back soon for more information as we are constantly updating our file descriptions based on search frequency.

Tip: Try to open the U3D file using a text-editor such as Notepad, as many file types contain simply contain unformatted plain-text and can viewed correctly using this method.

U3D is the Universal 3D format, developed by a diverse group of companies, but it has been slow to catch on.

It can be used by several drawing programs, but its most important use is probably embedding in .pdf files. It is the one 3D format that Adobe Acrobat supports, although it isn't supported in all PDF viewers.
