Files with the .SLDPRT extension can contain images, namely three-dimensional objects, or part of a file, which, coupled with other parts, can create a set saved in a single SLDASM file.

The SLDPRT 3D image format is created and used by the SolidWorks CAD software. Its viewing is also supported by the Adobe Acrobat 3D and Acrobat Pro software, versions 9 and above.
