Function Syntax: PLOTEXTRALOG Version: 1.0 Date: 15.07.2026 11:27:53AM N/A 🚀 Command Name 🧩 Type PLOTEXTRA018 at the AutoCAD command line. 🧩 Type PLOTEXTRALOG at the AutoCAD command line. 🧭 SEO Optimized Description 🖨️ PlotExtra is an SEO-friendly AutoCAD .NET plugin for improving layout plotting, page setup control, PDF output preparation, and plot preview workflows. 📐 The project captures layout geometry for a lightweight preview panel and exposes a custom plot dialog modeled after AutoCAD plot settings. 🧾 A dedicated log viewer command helps diagnose plot dialog actions, preview capture issues, and workflow status during testing. 🗂️ PDF project and age-tier configuration forms support project-based output management and visual organization of recently modified PDF files. 🎯 This is useful for Civil 3D plotting, AutoCAD sheet production, PDF export workflows, custom plot automation, and C# plugin UI development. 🧰 Main Workflow 1️⃣ NETLOAD the PlotExtra build DLL in AutoCAD or Civil 3D. 2️⃣ Run PLOTEXTRA018 to open the custom plot dialog. 3️⃣ Review page setup, device, paper, plot area, PDF, and preview information. 4️⃣ Use PLOTEXTRALOG to inspect runtime messages and preview diagnostics. 5️⃣ Adjust project/PDF settings and continue the plotting workflow. ✅ Functionalities ✅ 🖨️ Open a custom plot dialog from AutoCAD using a .NET command. ✅ 📐 Show a paper/layout preview based on captured drawing geometry. ✅ 🧾 Open a modeless log viewer with save and clear actions. ✅ 🗂️ Manage PDF project locations and project-specific plotting folders. ✅ 🎨 Use C3D dark/light palettes, compact buttons, and generated icons for consistent UI styling. ✅ ⚙️ Centralize build naming through project properties so command and assembly names follow the build number. ✅ 🧪 Provide a foundation for wiring UI fields to AutoCAD PlotSettings and PlotEngine logic. 🧩 Important Commands and Helper Functions 🧩 Commands.cs registers the plot dialog command and the PLOTEXTRALOG viewer command. 🧩 PlotDialogForm.cs contains the main WinForms plot interface and plot setting controls. 🧩 PreviewControl.cs renders sampled layout geometry in a reusable GDI+ preview panel. 🧩 PlotService.cs captures layout geometry and supports preview preparation. 🧩 Logger.cs records runtime messages for troubleshooting and workflow review. 🧩 PdfProjectConfig and PdfTierConfig store project output paths and file-age display tiers. 🧩 C3DTheme and ButtonIconFactory provide a consistent Civil 3D styled interface with reusable icons. 🎯 Practical Result 🎯 The result is a structured plotting workspace for AutoCAD and Civil 3D that supports preview, logging, project PDF settings, and future plot automation. 🧰 PlotExtra helps replace scattered manual plot setup steps with a single CAD-oriented interface designed for production sheet workflows. ✅ The project is especially useful as a C#/.NET template for custom plot tools, Civil 3D UI styling, and layout preview utilities. ⚠️ Important Notes ⚠️ The attached project is build 018; the generated command name is derived from the PlotExtra command prefix and build number. ⚠️ Some plot execution logic appears structured as a UI/preview foundation and may require final PlotSettings/PlotEngine wiring for real plotting in every environment. ⚠️ AutoCAD .NET plugins must be built against compatible x64 AutoCAD/Civil 3D assemblies before NETLOAD. 🏷️ Tags 🏷️ AutoCAD, 🏷️ Civil 3D, 🏷️ .NET, 🏷️ C#, 🏷️ AutoCAD Plugin, 🏷️ Plot Dialog, 🏷️ Plot Settings, 🏷️ PDF Plotting, 🏷️ Layout Preview, 🏷️ WinForms, 🏷️ PlotExtra, 🏷️ PLOTEXTRA018, 🏷️ PLOTEXTRALOG, 🏷️ CAD Automation, 🏷️ Sheet Production, 🏷️ C3D Theme
