.PRT 文件扩展名

A PRT file contains portal information used by the Valve Visible Information Set (VVIS) command-line tool included with Hammer Editor, which is a program used to build maps for Valve games such as Half-Life. It stores a list of portals in ASCII format that are used by VVIS to perform visibility calculations to determine which objects on a map can be seen by a player and must be rendered.

A PRT file is a template used by Corel Presentations, a presentation application part of the Corel WordPerfect Office suite. It contains predefined slide styles and layouts, allowing users to efficiently create new .SHW presentation files with consistent design elements.

Users save or export PRT files with Corel Presentations when defining custom templates. The templates streamline the presentation creation process by providing a uniform starting point for new projects, similar to how .POTX files work within Microsoft PowerPoint. The files typically reside within the Templates directory of a Corel WordPerfect Office installation.

You can open PRT files with Corel Presentations, part of the Corel WordPerfect Office suite. To open a PRT file with Presentations, select File → Open.

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.

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

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.

A PRT file is a 3D model file created by Solid Edge, a computer-aided design (CAD) application used to develop industrial parts and assemblies. It contains detailed part geometry, material properties, and other design parameters essential for building components. Solid Edge users often combine PRT files with other 3D parts to form assemblies, which are saved as .ASM files.

Engineers and designers in manufacturing and mechanical industries are the most likely to use PRT files for prototyping and product development. They generate PRT files by designing a component within Solid Edge, then save the design as a PRT file for later use in modeling, simulation, or production processes.

PRT files can also be referenced for technical documentation, analysis, or collaboration in design teams. These files can be exported in various formats for integration into other CAD applications, facilitating a flexible workflow across multiple design environments.

You can open PRT files with Siemens Solid Edge in Windows. To open a PRT file with Solid Edge, select File → Open.

Siemens Solid Edge can convert PRT files to several file types, including the following formats:

• .STP - STEP 3D Model
• .IGS – IGES Drawing
• .JT - JT Open CAD File
• .STL – Stereolithography File
• .OBJ - Wavefront 3D Object 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.

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