ViewCompanion Pro: The Complete Guide for CAD & PDF ViewingViewCompanion Pro is a powerful desktop application for viewing, printing, converting, and editing CAD and vector-based files. It supports a wide range of formats (including HPGL, HPGL/2, PLT, CALS, TIFF, DWF, CGM, SVG, PDF, and many CAD formats) and offers tools designed for engineers, draftsmen, printers, and anyone who needs precise control over technical drawings and vector documents. This guide covers installation, core features, workflows, advanced functions, tips for optimizing performance, common troubleshooting steps, and comparisons with alternatives.
What is ViewCompanion Pro?
ViewCompanion Pro is a Windows-based viewer and converter focusing on plotter and CAD file formats. It provides accurate rendering of vector data, supports batch processing for large numbers of files, and includes editing features such as markups, measurements, and layer control. The application is used across industries where precise handling of technical drawings is critical—manufacturing, engineering, architecture, and printing.
Supported File Formats
ViewCompanion Pro supports a broad set of raster and vector formats. Notable supported formats include:
- CAD and plotter: HPGL, HPGL/2, PLT, SVG, CGM
- Documents: PDF, DWF
- Raster: TIFF, JPEG, PNG, CALS
This wide compatibility makes ViewCompanion Pro a central tool for workflows that must translate between plotter files and modern document formats.
Installation and Licensing
Installation is straightforward—download the installer from the publisher’s website and follow the setup wizard. Licensing is typically offered as a paid single-user license with options for volume licensing for organizations. A trial version is often available to evaluate features before purchasing.
User Interface Overview
The UI is designed for efficiency:
- Main viewing pane with zoom, pan, and rotate tools
- Layer and pen/color management panels
- Toolbar for common actions: print, convert, batch process, measure
- Status bar with file info and current scale
Customization options allow you to arrange panels and toolbars to match your workflow.
Core Features
- Viewing and navigation: fast rendering, smooth zooming and panning, multi-page document support.
- Conversion: export between supported formats (e.g., PLT/HPGL to PDF, PDF to TIFF).
- Batch processing: automate conversions, print jobs, or rasterization for multiple files.
- Printing: precise scale control, tiling, and print to plotter or printer.
- Markup and annotations: place text, symbols, and graphical annotations; save as separate files or embed in output.
- Measurement tools: distance, area, and angle measurements with scale calibration.
- Layer and pen control: show/hide layers, remap colors and pen widths.
- OCR (in some versions or with plugins): extract text from raster images or PDFs.
Common Workflows
- Converting legacy PLT files to PDF for distribution
- Open PLT → adjust pens/layers → set page size → Export as PDF.
- Batch rasterizing drawings to TIFF for archival
- Use Batch Plot/Convert → select output format and resolution → run job.
- Reviewing and annotating drawings for manufacturing
- Open drawing → use markup tools to add notes and symbols → save annotated copy.
- Printing large drawings on multiple sheets (tiling)
- Set scale and tile layout → preview → send to plotter/printer.
Advanced Features and Tips
- Use pen and layer remapping to standardize output across different source files.
- Create and save export profiles for repeated batch jobs to save time.
- For large files, increase memory settings or use 64-bit version if available to improve performance.
- When converting to raster formats, choose appropriate DPI—300–600 DPI for print-quality archival.
- Use the measurement calibration tool to ensure distances match real-world units if source files lack embedded scale.
Performance Optimization
- Close unnecessary background applications to free RAM.
- Split extremely large multi-page documents into smaller batches for conversion.
- Disable complex rendering options (e.g., transparency) during review for faster navigation.
- Keep software updated; updates may include rendering and stability improvements.
Troubleshooting Common Issues
- Incorrect line weights/colors after conversion: check pen remapping and color settings.
- Missing fonts in PDFs: embed fonts during export or substitute fonts in settings.
- Slow rendering: try the 64-bit version, increase memory, or reduce display complexity.
- Batch job failures: verify file permissions and that source files aren’t open in another program.

Security and File Privacy
ViewCompanion Pro runs locally on Windows; files processed do not need to be uploaded to external servers, which is useful for sensitive engineering drawings. Always follow company policies for handling proprietary designs.
Licensing & Cost Considerations
Licensing models typically include single-seat licenses and volume discounts. Consider maintenance/support plans if you rely on the tool for critical workflows. Trial versions allow feature evaluation before purchase.
Final Thoughts
ViewCompanion Pro is a focused tool for professionals working with plotter and CAD file formats. Its strength lies in format compatibility, precise control over printing and conversion, and automation for batch processing. For organizations dealing with legacy plotter files or needing reliable conversions to PDF and raster formats, ViewCompanion Pro is a practical choice.
