What is a .plt file?

A PLT file is a vector graphics file format primarily associated with Hewlett-Packard Graphics Language (HPGL). HPGL is a printer control language used by pen plotters and other printing devices to create drawings, charts, and diagrams. PLT files contain instructions for the plotter to draw lines, curves, and shapes using a series of commands. These commands specify the coordinates, pen colors, and other parameters needed to render the graphic. PLT files are often used in CAD (Computer-Aided Design), engineering, and architecture for creating technical drawings and blueprints. While originally designed for pen plotters, PLT files can now be opened and viewed by various software applications that support vector graphics. The format is relatively simple and efficient for storing vector-based drawings, making it suitable for transferring graphical data between different systems. The file format is device-independent, meaning the same PLT file can be used to generate output on different plotters or viewing software, although the final appearance may vary slightly depending on the device's capabilities.
