How to Convert PLT (HPGL) into CDR
PLT files usually contain HPGL plotter commands (vector pen instructions). CorelDRAW can work with vector data but may not interpret every plotter-specific command exactly. The recommended approach is to import PLT/HPGL directly when supported or convert it to a widely accepted vector format (SVG, DXF, PDF) first, then open in CorelDRAW and save as CDR.
1. Import PLT/HPGL Directly in CorelDRAW
- Open CorelDRAW on your computer.
- Try File → Import and select the .plt (HPGL) file if supported.
- When prompted, verify units, scale, and layer/pen handling.
- Adjust stroke widths and placement if necessary, then save as .cdr.
2. Convert PLT to SVG/DXF/PDF if Direct Import Fails
For broader compatibility convert to a universal vector format first:
- Use a tool that reads HPGL (for example: Inkscape, pstoedit, or specialized PLT/HPGL converters) to export the file as SVG, DXF, or PDF.
- Open the exported SVG/DXF/PDF in CorelDRAW.
- Check scale, line weights, and any grouped objects, then save as CDR.
3. Online Conversion via Conholdate
If you prefer an online workflow, use Conholdate:
- Upload the PLT/HPGL file to products.conholdate.app and convert it to SVG or PDF.
- Download the converted file and import it into CorelDRAW.
- Finalize adjustments and save the project as .cdr.
4. Check and Fix Plotter-Specific Details
HPGL/PLT files often include pen, lift, and speed commands:
- Verify that pen colors/indices are mapped to stroke colors in CorelDRAW.
- Confirm the drawing scale (plotter units vs. mm/inches) and rescale if needed.
- Convert text to curves if fonts are missing or not supported.
- Clean up stray commands or tiny segments caused by plotter lifts before saving.
⚠️ Important:
PLT/HPGL is a device-oriented vector language — results depend on how the importer maps plotter commands to CorelDRAW paths. Converting via SVG or PDF generally preserves vector fidelity; always check scale and pen mappings after import.
