Can´t open PLT file

[erik_f]

I have created some PLT files from AutoCAD 2024 by checking the "Plot to File" option in the plot dialog.
However, I can't open the file using the "PLT2DWG" command.
The error I get when selecting my PLT file is: "The selected PLT file is not in the proper HPGL format."
What am I missing here?

Imports legacy HPGL files into the current drawing, retaining all colors.

Plot output (PLT) files can be created in the legacy HPGL (Hewlett Packard Graphics Language) vector format. You can use PLT2DWG to import the HPGL data into an AutoCAD drawing:

Command: PLT2DWG
Enter the plot file <Drawing>: Specify the file name or enter ~ to display the File dialog box

The HPGL/2 format, the successor to HPGL, is device-dependent and not supported by PLT2DWG.

Note: PLT2DWG does not support Draftpro DXL and Draftpro EXL which are listed as options 6 and 7 in the Supported Models section under the Hewlett-Packard (HP-GL) ADI 4.2 - by Autodesk, Inc. device driver. Also, the default system printer and the HPGL/2 printer are not supported.

Hi,

Command PLT2DWG and what you missing is explained above.

To check the .plt content, you should use a .plt VIEWER what supports hpgl .plt files.

As the returned message states the "PLT2DWG" command only works on plt files that are created compatible to HPGL format.  So the pc3 device you select to generate the plt file needs to conform to this standard

heres another thread awhile back on the same topic

Hi,

>> "The selected PLT file is not in the proper HPGL format."

This message indicates that the PLT file you are attempting to use is not a valid HPGL file, or at least not in a format recognized by the specific software or tool you are using.

After returning to Autodesk Support the answer was:  " Some online resources offer conversion from PLT to other formats. Also, there are 3rd party software programs which can convert HP-GL/2 formatted PLTs into DXF and other formats."
