.PLT File Extension

Vector-based plotter file created by AutoCAD drawing software; can be printed using a plotter, which prints images using lines instead of dots; based on the HPGL format.

Plotter file created using the Hewlett-Packard Graphics Language (HPGL); contains a series of two-letter codes, such as "IP," which declares the initial point on a plot; may contain optional parameters with the codes; used by various drawing programs and printers for creating printable plotter documents.

PLT files can be scaled to different sizes without losing quality. They are stored in an ASCII text format.

PLT files are the same as .HPG files.

Data file created by Tecplot, a scientific visualization program; saves output data created through a scientific computation in the software; may contain multiple frames and datasets; used for rendering complex 2D and 3D visualizations and may be rendered to a static image or an animated visualization.

Tecplot also offers an ASCII text format for data output. However, this format is discouraged for larger datasets since it renders much more slowly than the PLT binary format in the software.
