HPGL / PLT to DWG / DXF / PDF conversion software

Easy 3 steps to (batch) convert PLT to DWG (PLT to DXF or HPGL to DWG):

Step 1: Select DWG as Output Format and click the '...' button.

Step 2: Select a file to convert and then click the Open button.

Step 3: Press the Convert button. Once the translation ends, press the View Output button. Then you can see a resultant DWG/DXF file on your CAD file viewer.

Batch Conversion: You just need to type "*"(asterisk), "."(dot) and file extension in both Input and Output. For example: *.plt in Input and *.dwg in Output. Then press the Convert button. In case of HPGL file, type *.hpgl in Input.

Your Feature Complete Solution!

Support File format types:

 • As input file, HPGL plot file format (*.hpgl and *.plt).
 • As output file, PDF and All AutoCAD DXF/DWG versions through to AutoCAD 2025 are supported.

Batch Conversion:

 • Batch conversion on the software interface.
 • Batch conversion via command line.
 • Allows wild card file naming to be used - i.e. translate *.plt *.dxf or *.plt *.dwg etc.
 • Command Line mode allows automated conversions.

Handy conversion features:

 • Support multi-folio (multi-page) plot files. Each page is output to a separate DXF/DWG file.
 • Efficient output. e.g. makes use of R14+ DXF/DWG HATCH entity instead of outputting multiple lines.
 • option to join lines and arcs to single polyline.
 • output HPGL 'dot' as Point, or ignore, in preference to the HP defined 'unit length vector'.

Polyline Widths conversion feature:

 • If selected, all line entities will be output as 2D Polylines/LWPolylines with widths corresponding to the originating plot file Pen Widths.

Line Weights feature:

 • If selected, then for AutoCAD 2000+ versions of DXF/DWG Pen Widths in the plot file are translated to Line Weight values in the output file.

Output drawing rotation:

 • Apply a rotation to the translation. Available rotation values are 0,90,180,270 degrees.
