Convert CDT to PLT

Understanding CDT and PLT file formats

CDT files are CorelDRAW template files, used to store pre-designed layouts, graphics, and settings for creating new documents in CorelDRAW. These templates help users maintain consistency across multiple projects.

PLT files are plotter files based on the HPGL (Hewlett-Packard Graphics Language) standard. They are commonly used for sending vector graphics to plotter printers, especially in engineering, CAD, and architectural applications.

Why convert CDT to PLT?

Converting a CDT template to a PLT file allows you to use your CorelDRAW designs with plotter hardware or CAD software that supports the HPGL format. This is essential for producing large-scale technical drawings or signage.

How to convert CDT to PLT

Since CDT is a proprietary CorelDRAW format, the most reliable way to convert it to PLT is by using CorelDRAW itself. Here’s how you can do it:

1. Open your CDT file in CorelDRAW.
2. Go to File → Save As or File → Export.
3. In the Save as type dropdown, select PLT - HPGL Plotter File (*.plt).
4. Click Save and adjust any export settings as needed for your plotter.

Best software for CDT to PLT conversion

• CorelDRAW – The native application for CDT files, offering direct export to PLT.
• ABViewer – A versatile CAD viewer and converter that supports PLT files, but you must first save your CDT as CDR in CorelDRAW.

Online converters generally do not support CDT files due to their proprietary nature, so using CorelDRAW is recommended.

Tips for successful conversion

• Before exporting, ensure all fonts and graphics are properly embedded or converted to curves.
• Check plotter settings such as page size, pen width, and color mapping in the export dialog.
• Test the PLT file with your plotter or a PLT viewer to verify accuracy.
