File extension .X_B

Parasolid Document Format | Siemens PLM Software | CAD Files |
The X_B file extension is a 3D CAD modeller part format, commonly used by Parasolid software. This file format is used to store data and changes related to the 3D models that have been designed and constructed using Parasolid CAD modelling tools.
The X_B file format is based on and follows the currently accepted industry standards for universal 3D data exchange, such as the STEP-AP 203 Standard, as well as those used by the modelling packages from Siemens PLM Software. This allows for easy transfer and exchange of models between multiple software systems, including compatibly created 3D files.
The X_B file extension also stores grid mesh data, which is the foundation of the model's geometry, and which drives its functionality in design environments. These arrays of polygons are driven by the model's visual cues, such as line colours, object markers, fill patterns, texture and other related information.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .X_B) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .X_B extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .X_B file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .X_B extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .X_B extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .X_B file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .X_B file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .X_B file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .X_B file) will be extended to the maximum.
It is also good to check
- if the .X_B file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
