Function Syntax: UpdateSectionBandSets Version: 1.0 Date: 05.06.2026 2:49:03PM N/A short_description: | SEO Description 🚀 UpdateSectionBandSets is an AutoCAD Civil 3D .NET Framework plugin for editing Section View band sets, band styles, and section data sources. It helps Civil 3D users update top and bottom section view bands faster, improve annotation consistency, and reduce repetitive manual drawing work. command: | Main Command and Loading Method 🧰 Load the plugin with NETLOAD and select UpdateSectionBandSets.dll. 🚀 Run UpdateSectionBandSets to open the Civil 3D Section View Band Manager. 📌 Target platform: AutoCAD Civil 3D x64 with a C# .NET Framework 4.8 plugin. 🧩 Uses Civil 3D and AutoCAD managed assemblies such as AeccDbMgd, Acdbmgd, Acmgd, and accoremgd. description: | Detailed Description 📘 The program scans the active Civil 3D drawing and loads available SectionView objects into a selection list. 🔍 The user selects a Section View and reviews its top and bottom band rows inside an editable grid. 📊 The grid exposes practical fields such as Location, Band Style Name, Section 1 Data Source, and Section 2 Data Source. 🎨 The user can assign Civil 3D section view band styles and adjust the section data sources used by each band row. The result is faster Section View band set editing, cleaner Civil 3D annotation management, and fewer repetitive manual steps. Important limitation: The tool updates band set configuration for existing Section Views; it does not create alignments, sample lines, corridors, surfaces, or new Section Views. helper_function: | Helper Logic 🧰 Command registration system - LaunchSectionBandUpdaterDialog opens the Section Band Updater dialog from the AutoCAD command line. 🔍 Drawing data scan - LoadInitialDrawingData reads the active CivilDocument, SectionViews, Sections, SampleLines, and band style collections. 📐 Section View selector - cmbSectionViews and CmbSectionViews_SelectedIndexChanged refresh the grid when the selected Section View changes. 📊 Band grid population - PopulateGridBands fills dgvBands with top and bottom Section View band rows. 🧩 Metadata mapping - SectionBandRowMeta, SectionViewMeta, SectionViewBandItem, and BandSetItem keep ObjectId references aligned with grid rows. 🎨 Style collection access - the plugin reads BandStylesRoot, SectionViewSectionDataBandStyles, and SectionViewSegmentsBandStyles from the Civil 3D document. 🔄 Top and bottom band workflow - GetTopBandItems, SetTopBandItems, GetBottomBandItems, and SetBottomBandItems manage band location-specific updates. 🔒 Transaction-safe database updates - StartTransaction, GetObject, and Commit apply changes safely to the AutoCAD database. 🔴 Error handling - MessageBox feedback reports success, database errors, and update failures. functionalities: | Functionalities 🚀 Open Section View Band Manager - launches a focused Civil 3D dialog for section view band set editing. 🔍 List Civil 3D Section Views - scans the active DWG and lets the user choose the target Section View. 📊 Review band rows in a grid - displays top and bottom band entries with location, style, and data source columns. 🎨 Update band styles - assigns Civil 3D section view band styles from available drawing style collections. 📐 Change section data sources - edits Section 1 and Section 2 sources used by section view band rows. 🔄 Update top and bottom bands - applies changes to both upper and lower Section View band sets. 🧠 Use ObjectId-based mapping - targets the correct Section View, section sources, sample lines, and styles. 🔒 Apply database-safe changes - uses AutoCAD transaction logic for safer drawing modification. ✅ Confirm update results - reports successful Section View updates and database errors. result: | Final Result ✅ The final result is a productivity-focused AutoCAD Civil 3D plugin for faster Section View band set updates. It improves drawing consistency, reduces manual Civil 3D dialog work, and supports better section annotation management in production DWG files. additional_info: | Additional Notes 📌 The uploaded package contains the compiled UpdateSectionBandSets.dll and UpdateSectionBandSets.pdb. 🧩 The description is based on compiled metadata, embedded UI strings, command names, and detected AutoCAD Civil 3D API usage. 🔴 Test the command on a copy of the DWG before applying band set changes to production drawings.
