PLT Export for SolidWorks (formerly HPGL Export for SolidWorks) — Quick Overview

How to Use PLT Export for SolidWorks (formerly HPGL Export for SolidWorks)

Overview

PLT Export for SolidWorks converts SolidWorks drawings and vector geometry into PLT/HPGL files for plotters and cutting machines. It preserves line types, layers, and scale while offering export options for precision and device compatibility.

Step-by-step guide

1. Install and enable the add-in

   • Download the PLT Export add-in compatible with your SolidWorks version.
   • In SolidWorks: Tools → Add-Ins → check the plugin for the current session and/or startup.

2. Prepare your SolidWorks drawing/model

   • Layers/line types: Use distinct layers and correct line types for elements you want preserved.
   • Scale and units: Set drawing scale and units (Tools → Options → Document Properties → Units).
   • Simplify geometry: Remove small or unnecessary entities and convert splines to polylines if your target device prefers straight segments.

3. Open the PLT Export dialog

   • With the drawing active: File → Save As → choose “PLT/HPGL” or use the add-in toolbar/menu to open the export dialog.

4. Configure export settings

   • Device/plotter selection: Pick the target device profile or define custom plotter parameters (page size, resolution, pen assignments).
   • Scale/fit options: Choose to use drawing scale or fit to page; set output units (inches, mm).
   • Line mapping: Map SolidWorks layers/line types to PLT pens; assign pen widths and colors as needed.
   • Curve handling: Specify polyline approximation tolerance for splines and arcs to control output fidelity vs. file size.
   • Text handling: Choose to export text as vectors or keep as device text (if supported).
   • Optimization: Enable path optimization to reduce cutter/plotter travel and improve performance.
   • Advanced: Set character encoding, end-of-file markers, and include or strip header comments.

5. Preview the output

   • Use the built-in preview to check scaling, pen assignments, and missing geometry. Zoom to critical areas and adjust tolerance or layer mapping if needed.

6. Export and test

   • Export to a PLT file and test on target hardware or in a PLT viewer. Verify line weights, text readability, and overall scale.
   • If issues appear, return to the export settings to tweak pen mappings, scale, or curve approximation.

7. Common troubleshooting

   • Missing entities: Ensure layers aren’t set to hidden; explode complex features or convert blocks.
   • Text unreadable: Increase text vectorization quality or export as device text.
   • Too many segments: Reduce spline-to-polyline tolerance to limit segment count.
   • Incorrect scale: Verify document units and scale in both SolidWorks and export dialog.

Tips

• Save export presets for repeated jobs.
• Create device-specific layer-to-pen mappings.
• For cutting machines, use single continuous paths where possible and enable path optimization.
• Keep a small test file to quickly validate settings before full exports.

Example quick settings (recommended starting point)

• Units: mm; Scale: Use drawing scale; Curve tolerance: 0.01–0.1 mm; Pen mapping: map major layers to pens 1–4; Path optimization: ON.
