.X_B is related with Parasolid software. This is a geometric modeling kernel which contains a number of geometrical model creation and editing tools.
The file extension used by this software application is .X_B. This format is binary format of saved file therefore making this file more machine independent and is also not subjected to binary to text conversion errors which can cause change in geometry in most of the cases. Generally this file type is used to define 3D models and is not suitable for defining 2D elements. This file type contains geometrical information about the object with its rendering.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .X_B file, there may be several reasons that cause problems with opening and operation of the data format:
A quite common problem is the lack of application in the appropriate version. Even if you have an application, with the help of which you should open the .X_B file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .X_B file, so download the update and check again.
If you have already installed the appropriate application, and it is the correct version, the file may not open correctly, because the operating system does not have information that this program supports the file. So you need to "show" which program the computer should use. To do this:
It also happens that the file you want to open is corrupt and therefore there is no such possibility. In this situation, you should find its different version, or ask a person from whom you got, to send it again.
There may be several reasons why you cannot open the file with .X_B extension. Directly on this website you can find a solution of the most common problem with the .X_B file – that you do not have on your computer the appropriate program to open the file.
