Opening X_T files

Did your computer fail to open a X_T file? We explain what X_T files are and recommend software that we know can open or convert your X_T files.

What is a X_T file?

The .x_t file extension is used for a proprietary CAD and 3D graphics file format, which was developed by Siemens Product Lifecycle Management (PLM) Software, Inc. The X_T file format is used for the geometric CAD modelling kernel that was created by ShapeData, which was then acquired by Siemens PLM and packaged as the Parasolid kernel. Other companies are able to use Parasolid for their 3D graphics modelling and CAD software tools through a license from Siemens PLM.These X_T files are encoded in plain text format and can support high precision boundary-representation technologies. These include free form surface/sheet modeling, generalized cellular modeling and solid modelling within an integrated CAD framework.These X_T files can normally be found in computers where Parasolid-based 3D graphics modelling tools and CAD programs are installed. It's best to leave these .x_t files alone. These are not meant to be opened and can only be used by Parasolid-based CAD applications and 3D graphics modelling programs.
