Function Syntax: MatchProjectionStyles / MatchProjectionStylesVersion / MatchProjectionStylesDiag / MatchProjectionStylesDump Version: 1.0 Date: 11.06.2026 1:19:26PM N/A short_description: Short SEO Description 🚀 MatchProjectionStyles is an AutoCAD Civil 3D .NET Framework plugin for fast Section View projection and crossing style management. It helps CAD users inspect, filter, edit, export, undo, redo, and apply Civil 3D Section View style data from one modeless manager. The main benefit is faster Civil 3D section drawing cleanup, consistent projected object styling, and improved AutoCAD Civil 3D productivity. command: Main Command and Loading Method 🧰 Load the plugin with NETLOAD by selecting MatchProjectionStyles.dll. Run MATCHPROJECTIONSTYLES to open the Section Style Manager inside AutoCAD Civil 3D. Run MATCHPROJECTIONSTYLESVERSION to show version, DLL path, DLL age, and log path information. Run MATCHPROJECTIONSTYLESDIAG to run a Civil 3D API self-test. Run MATCHPROJECTIONSTYLESDUMP to dump Section and Section View property data for troubleshooting. The target platform is AutoCAD Civil 3D x64 using a C# .NET Framework 4.8 plugin. description: Detailed Description 📘 This plugin scans the active Civil 3D drawing and collects Alignments, Sample Line Groups, Sample Lines, Section Views, crossing objects, projection objects, styles, labels, and elevation options. 🔍 The top grid displays Section View based data, including alignment, group, section view, object type, source object, crossing marker style, crossing label style, projection style, elevation option, elevation value, and status. 🧠 The bottom object-centric panel lets the user pick one projected source object and bulk-edit every Section View row that contains that object. 🎨 Users can change Section View styles, crossing marker styles, crossing label styles, projection styles, draw crossing options, draw projection options, and elevation options where the Civil 3D API exposes writable data. 📊 The interface includes filtering, check all, check none, reset, refresh, copy table, CSV export, apply, apply and close, undo, redo, diagnostics, and log viewer tools. Important limitation: This project does not create Alignments, Profile Views, Section Views, Sample Lines, bands, labels, surfaces, corridors, or Civil 3D styles. Its purpose is AutoCAD Civil 3D Section View projection and crossing style management for existing drawing data. helper_function: Helper Logic 🚀 Command registration system - MatchProjectionStylesPlugin registers the main command, version command, diagnostic command, and dump command. 🔍 Civil 3D data collector - SectionDataCollector.CollectFromDoc() reads Civil 3D Section View, Section, crossing, projection, style, label, and elevation information. 📐 Alignment traversal - the collector walks Alignment, SampleLineGroup, SampleLine, and SectionView objects. 🧩 Crossing row model - CrossingObjectRow stores current values and pending values for marker, label, projection, elevation, and draw options. 📊 Section View model - ViewItem connects alignment, group, Section View, current style, new style, apply state, and crossing rows. 🎨 Apply engine - SectionStyleEngine.Apply() writes changes back to Civil 3D objects using transactions. 🔐 Document safety - doc.LockDocument() is used before database writes to reduce eLockViolation problems. 🧠 Reflection fallback - TryWriteSvCrossingState() attempts available Civil 3D crossing-data methods and properties. 🔄 Bulk editing engine - CrossingStyleEngine applies marker, label, projection, elevation, and draw state changes across filtered crossing rows. ↩️ Undo and redo model - UndoRedoStack, StyleBatch, ViewSnapshot, and CrossingSnapshot preserve previous applied state. 📝 Logging and diagnostics - SectionLogger and LogViewerForm support QA, debugging, warning review, and version checks. functionalities: Functionalities 🚀 Open modeless style manager - manages Civil 3D Section View, projection, crossing, and elevation style data without blocking AutoCAD interaction. 🔍 Scan active Civil 3D drawing - collects Section View rows from existing alignments, sample line groups, and sample lines. 📊 Review Section View data - displays alignment, group, Section View, object type, source object, styles, elevation values, and status. 🎨 Change Section View styles - applies selected Section View styles to checked rows. 🟧 Change crossing marker styles - standardizes marker display for Civil 3D crossing objects. 🏷️ Change crossing label styles - updates crossing labels where Civil 3D exposes writable label style access. 📐 Change projection styles - manages projection style settings for projected source objects. 🔢 Set elevation options - works with Use Object, Manual, and Surface based elevation options. 🧩 Bulk edit by source object - edits all Section Views containing the same projected object from the bottom panel. 🧠 Filter large projects - filters by alignment, group, Section View, object category, and source object name. 🔄 Refresh and reset - reloads drawing data and clears pending edits when needed. ↩️ Undo and redo changes - reverses or reapplies recent style batches. 📤 Export and copy table data - creates CSV output and clipboard text for QA and coordination. 🧰 Run diagnostics - checks Civil 3D API access, style collections, Section data, and plugin version details. result: Final Result ✅ The final result is a productivity-focused AutoCAD Civil 3D tool for managing existing Section View projection and crossing style data from a single grid interface. It reduces repetitive manual editing, improves drawing standardization, supports faster Section View cleanup, and gives Civil 3D users better control over projection styles, crossing styles, elevation options, QA exports, and diagnostic logs. additional_info: Important Notes and Configuration 🔐 The project targets net48 and x64 AutoCAD Civil 3D. 📌 The project file imports a machine-specific ObjectARX reference file named AutoCAD_Civil3D_refferences.props. ⚠️ Some crossing and projection properties depend on Civil 3D API availability in the installed version. 🔴 The tool manages existing Section View projection and crossing style data only. It does not create Profile Views, Alignments, Section Views, labels, bands, corridors, surfaces, or styles.
