PLO to CG4 Conversion: FAQ

What are PLO files?

The .plo file format is a variant of the HPGL (Hewlett-Packard Graphics Language) format, commonly used for plotter files. Like standard .hpgl files, .plo files contain a series of vector instructions—written in ASCII—that control pen movements on plotting devices. These files are typically generated by CAD software and used in engineering, architecture, and manufacturing to produce precise line drawings. The .plo extension is often used to distinguish plot-ready files prepared specifically for output on plotters, while still following the HPGL command structure.

What are CG4 files?

CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data.
