Troubleshooting CTB Plots & Pen Styles
1. How to use PCP/CTB configuration files in AutoCAD
Importing PCP mapping settings: When running plot outputs in AutoCAD, you can import our generated `.pcp` table structure by typing the command STYLEMANAGER.
Copy the downloaded PCP parameters file into the AutoCAD Plot Styles directory, or choose the Custom Import option inside the wizard config layout selector to apply the exact pen weights mapped from this visualizer.
Setting CTB globally: Ensure your drawing is set to use color-dependent plot styles (CTB) rather than named plot styles (STB). You can toggle this using the CONVERTPSTYLES command if your drawing properties are locked to STB formatting.
2. Industry standard pen thickness conventions
To maintain standard engineering and architectural layout styles (ISO/ANSI drafting guidelines), we recommend assigning the following line weights to standard color codes:
- ACI 1 (Red): 0.18 mm — Center lines, grids, hatch contours.
- ACI 2 (Yellow): 0.25 mm — Dimensions, annotation tags, leaders.
- ACI 3 (Green): 0.35 mm — Standard structural walls, visible geometry.
- ACI 4 (Cyan): 0.50 mm — Heavy cut-through lines, room boundaries.
- ACI 5 (Blue): 0.70 mm — Extruded border margins, heavy structures.
- ACI 8/9 (Greys): 0.13 - 0.15 mm — Hatch fills (screening at 50% density).
