The .X_T file format is associated with Parasolid. This is a geometry modeling kernel which was originally created by ShapeData.
This kernel is used for model developing and editing purposes. The features added in this kernel include feature modeling support, Boolean modeling operators, hollowing, thickening, advanced surfacing, sheet modeling, filleting and blending. If any 3D model is designed in this environment, its details are saved in .X_T file format. This file format contains information which is required by the kernel to define the geometry and render it in the environment. This file is specifically used for storing 3D data type.
In addition to the problem described above, i.e. the lack of the appropriate application to support the .X_T 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_T file, you may have a problem with it because of its version. Perhaps in previous versions the application has not yet supported the .X_T 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_T extension. Directly on this website you can find a solution of the most common problem with the .X_T file – that you do not have on your computer the appropriate program to open the file.
