HPGL2CAD

With a name that clearly indicates its basic features and capabilities, HPGL2CAD is a lightweight and efficient piece of software that allows you to quickly convert HPGL, HP-GL, and PLT files to DWG and DXF, both formats that are supported by a multitude of CAD applications out there.

Before anything else, you should be aware of the fact that this application is capable of outputting files compatible with all version of AutoCAD, starting from AutoCAD 11, 12, 13, and 14, all the way up to  AutoCAD 2016.

Deploying this utility on your computer's system is by no means challenging, thanks to a streamlined installer that does not require much user intervention in order to get the job done.

The application sports a somewhat outdated user interface but, thanks to its intuitive layout and small set of features, it should not pose any kind of difficulties.

To start working with this utility, simply load the input file, select the output location, pick the version of AutoCAD and choose one of the two output options, namely DXF and DWG and, finally, hit the 'Translate' button.

Please note that you can also rotate the output file at 90, 180 and 270 degrees as well as choose the decimal place threshold. The application provides you with accurate information regarding the entire conversion process on the lower part of the main window.

This said, are looking for a quick way to convert HPGL, HP-GL and PLT files to formats widely-supported by AutoCAD or other CAD apps, then HPGL2CAD surely fits the bill.

For some users, the only drawback might be the fact that it does not come with a built-in viewer, which, truth be told, could have slowed the app down quite a lot.
