.PRT File Extension

A PRT file is a part file created by PTC Creo Parametric, a CAD program part of the Creo suite that is used to design manufactured parts and assembly processes. It contains part information, including a 3D model and part structure. PRT files can be combined with other parts into an assembly file (.ASM file).

PTC Creo Parametric was formerly known as Pro/ENGINEER but was renamed in 2010. PTC stands for Parametric Technology Corporation.

CAD file created by CADKEY, a program used for designing 2D and 3D parts; contains both the model and drawing layouts; includes model geometry in wireframe, surface, and solids (ACIS based), plus dimensioning, annotation, vector, plane and other entity types in one modeling space.

The Drawing Layout Mode in CADKEY contains defined views of model geometry for associative dimensioning and annotation, as well as section views. It also allows 2D wireframe geometry creation.

NOTE: KeyCreator, the successor to CADKEY, uses .CKD files to store designs.

Presentation template created by Corel Presentations, an application included with Corel WordPerfect Office; saves a slide style and layout that can be used for creating new .SHW presentations.

A PRT file is a model part file saved in a three-dimensional model format used by Unigraphics, a 3D CAD program. It contains surface and solid information for a single part. PRT files are saved in a binary format, similar to an Alias wire model and an SDRC (Structural Dynamics Research Corporation) model.

NOTE: Unigraphics was acquired by Siemens and is now distributed as Siemens NX.

3D model created with Solid Edge, a CAD program used primarily for creating industrial parts and assemblies; can be combined with other 3D parts in an assembly (.ASM) file.

Contains configuration information that allows the computer to communicate with the printer; may be used by certain software programs, such as Dr. Halo software, which saves images in a device-independent format.

Output from a printing job sent to the printer and saved as a file; contains formatting information that tells the printer how the document should be printed.

PRT files may be created on Unix systems using the FILEUTIL function with a Filename parameter. They can also be opened by FILEUTIL and printed using the LP (line printer) parameter.

Protected text document created by Crypt Edit, a free program used for word processing; stores an encrypted and password protected document; may contain text, images, and page formatting information; used to securely store documents.

NOTE: PolySoft Solutions discontinued development for Crypt Edit in 2000.
