An X_B file is a Parasolid binary model file used in 3D CAD design, engineering, and manufacturing. In simple terms, it is a file that stores the actual 3D shape of a part or object, not just a picture or drawing of it. It is commonly used to exchange 3D models between CAD programs such as SolidWorks, Siemens NX, Solid Edge, Autodesk Inventor, Onshape, and other software that can import Parasolid files.
If you have any type of questions concerning where and how to utilize X_B file opener, you can call us at our own page. The word Parasolid refers to the 3D modeling technology used to define the geometry of the object. Many CAD programs use Parasolid as their geometry engine, which is why X_B files are widely supported in engineering and product design. The binary part means the file is saved in a compact machine-readable format. Unlike a text file, an X_B file is not meant to be opened in Notepad or edited manually. If you try to open it using a basic text editor, the contents will usually appear as unreadable symbols or random characters.
An X_B file may contain solid bodies, which are complete 3D objects that CAD software understands as having real shape, thickness, and volume. For example, a bolt, bracket, gear, pipe fitting, machine part, or plastic casing can be stored as a solid body. A solid body is different from a flat drawing because the CAD software can rotate it, measure it, calculate its volume, inspect its surfaces, and check how it fits with other parts. It may include faces, edges, curves, holes, rounded corners, cutouts, and other geometric details that define the finished object.
X_B files may also contain surface bodies, which are surfaces or skins without full enclosed volume. A solid body is like a complete sealed 3D object, while a surface body is more like a sheet or outer skin. Both can be useful in CAD work, but solid bodies are more commonly associated with parts that can be measured, machined, assembled, or manufactured.
One important thing to understand is that an X_B file usually stores the finished 3D geometry, not the full design history. For example, the original CAD file may have been created using sketches, extrusions, cuts, fillets, chamfers, and hole features. When that model is exported as an X_B file, the receiving software may only see the final shape instead of all the original steps used to create it. This means the file can often be opened, measured, inspected, and modified, but it may not show the original feature tree from the program where it was designed.
The related file type X_T is also a Parasolid file, but it is the text-based version. The X_B format is binary, which usually makes it more compact and efficient for software to read, while X_T is stored as text. Both formats can contain similar 3D CAD geometry, but X_B is generally the more compact binary version.
In SolidWorks, an X_B file can usually be opened or imported because SolidWorks also uses Parasolid geometry. However, the file will often appear as an imported body rather than a fully editable native SolidWorks part. Instead of seeing a full feature tree such as Sketch, Extrude, Cut, Fillet, and Chamfer, you may only see something like “Imported1” or “Solid Body.” You can still perform many edits using direct editing tools, add new cuts or holes, measure the part, create drawings, and save it as a SolidWorks part file, but the original modeling steps are usually not restored.
X_B files are often shared by engineers, product designers, machine shops, mold makers, manufacturers, and CAD contractors. They are useful when someone wants to send the accurate 3D geometry of a part without sending the original native CAD file. For example, instead of sending a SolidWorks `.sldprt` file, a designer may export the model as an `.x_b` file so another person using a different CAD program can import and use the geometry.
In plain English, an X_B file is a compact 3D CAD design file that contains the actual digital shape of a part or model. It is used for engineering, product design, manufacturing, CNC machining, mold making, assembly checking, and sometimes 3D printing preparation. It is not a regular document, image, or video file. To open it properly, you need CAD software or a compatible 3D model viewer.
