How to convert PLT to DWG with Amethyst PLT-2-DWG

How to convert PLT to DWG with Amethyst PLT-2-DWG How to convert PLT to DWG with Amethyst PLT-2-DWG

Every AutoCAD user should know what exactly PLT and DWG files are, because DWG is the native format for several CAD (Computer-Aided Design) applications (including AutoCAD, Caddie or IntelliCAD) used for storing 2D and 3D designs and metadata; and PLT, also known as HPGL, implies plotter files that are mainly created with AutoCAD. Basically, PLT files contain a set of commands that are issued to a vector graphics printer (plotter) to produce the desired result. Even though converting DWG files to PLT format is a simple task using CAD software, turning them back to a drawing can be quite tricky. This is where specialized applications (or converters) step in to help you out.

Next, I will show you how you can transform PLT files into AutoCAD DWG drawings using Amethyst PLT-2-DWG 3.0 (Shareware $75.00) by CA Design Associates LTD. I have selected this application because it is a powerful, yet easy-to-use converter that has a good quality-price report (compared to several other programs). Also, it can save you some time by converting multiple files at once (batch conversion).

You can never perform a 100% conversion from a PLT file back to a DWG drawing, because the PLT file doesn't contain all of the original file's information.

This software comes with a 15-day free trial that has certain features disabled until being purchased.

Here is the step-by-step guide for converting PLT files into DWG drawings

Step 1

Add the PLT files. You can either individually add the desired files ("Add Files" button) or add an entire folder ("Add Folder"). 

Step 2

Select the AutoCAD version for the DWG file from the drop-down menu.

Step 2.1

Before starting the conversion process, you can modify several settings by clicking on the "Conversion Options" button. You can change the color palette used for the DWG drawing as well as the text size.


Step 3

Choose the output directory (or leave the default one) and press on the "Convert" button to start the process. If it takes too long, you can always press the "Escape" button on your keyboard to stop the task.


Well done! You have successfully changed your PLT files into DWG drawings. After the conversion process is complete, a log will appear to display detailed information about the completed task. As you might have noticed, converting PLT files to DWG format using Amethyst PLT-2-DWG 3.0 is as easy as 1-2-3 and the entire process should take very little of your time, thanks to the program's fast conversion speed.
