PRT file extension - CAD 3D part or component

What is prt file? How to open prt files?

File type specification:

3d graphics, CAD-CAM-CAE file type icon 3d graphics, CAD-CAM-CAE file type

File extension prt is frequently used by various CAD software for files that contains 3D information about specific part or component. These are very often part of some large projects.

This is not a generic format, unique .prt files are often in completely different format, just share the same file extension.

In the MCAD world, geometry is contained in individual "part files" using common extensions such as part, prt, and sldprt.

Multiple parts are then placed into the final 3D scene using one or more "assembly files", which use such common extensions as asm or assem.

The assembly file allows one geometry part file to be instanced one or many times without duplicating the base geometry and for material overrides to be placed on each instanced part file.

Some formats are interchangeable, while others are proprietary and cannot be used outside the original application.
