U3D extension files belong to the category of graphic files. The content of files with the U3D extension includes three-dimensional models.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the U3D file after converting to IGES may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from U3D to IGES to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting U3D to IGES does not meet your expectations, you can simply try to find on the Internet a different version of your file in U3D format, properly converted to a IGES file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file U3D the desired result was not achieved, you can try to change the format of U3D file to other than IGES. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your U3D file converted by someone else, and the attempt to convert it to IGES on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the U3D file in its original format (without conversion to IGES file). Such a solution will be difficult to implement, but it certainly will give the best result.
