A CALS (Continuous Acquisition and Life-cycle Support) file is part of a set of standards developed by the U.S. Department of Defense (DoD) for the representation and interchange of technical data and engineering drawings. CALS files are commonly associated with raster graphics used in engineering and technical documentation.
What is a CALS File?
CALS files can be in various formats, such as CALS Type 1 (also known as MIL-R-28002), CALS Type 2, or CALS Type 4. They often include black-and-white or grayscale images, and the standardization ensures compatibility and interchangeability of technical data within the defense and manufacturing sectors.
How to Open CALS Files
To open CALS files, you’ll need software that supports the CALS standards. Here are some options:
1. ACDSee Photo Studio: ACDSee is an image viewer and editor that supports various file formats, including CALS. It provides tools for viewing and basic editing of images.
2. IrfanView: IrfanView is a versatile and lightweight image viewer that supports a wide range of file formats, including CALS. It is suitable for quick viewing and simple editing tasks.
3. Adobe Acrobat: CALS files may be converted to PDF format for easier viewing and sharing. Adobe Acrobat, the PDF creation and viewing software, can be used for this purpose.
4. CorelDRAW Graphics Suite: CorelDRAW, a vector graphics editor, may support CALS files, especially in scenarios where technical illustrations or engineering drawings need to be accessed.
5. AutoCAD: AutoCAD, a widely used software for computer-aided design (CAD), may have the capability to handle CALS files, particularly in engineering and design workflows.
Various Apps that Use Files with CALS Extension
CALS files are primarily used in engineering, defense, and manufacturing contexts for the exchange of technical data. Various applications that generate or use CALS files include:
