Short description
🚀 UpdateSectionBandSets is an AutoCAD Civil 3D .NET Framework plugin for editing Section View band sets, band styles, and section data sources from a focused grid-based dialog. It helps Civil 3D users update top and bottom section view bands faster, reduce repetitive manual edits, and improve section view annotation consistency in production drawings.
Command:
🧰 Load the plugin in AutoCAD Civil 3D with NETLOAD and select UpdateSectionBandSets.dll.
🚀 Run the main command UpdateSectionBandSets to open the Civil 3D Section View Band Manager dialog.
📌 The target platform is AutoCAD Civil 3D x64 with a C# .NET Framework 4.8 managed plugin.
🧩 The compiled assembly uses AutoCAD and Civil 3D managed APIs including Acdbmgd, Acmgd, accoremgd, and AeccDbMgd.
Description:
📘 UpdateSectionBandSets scans the active Civil 3D drawing, reads available SectionView objects, collects their existing top and bottom section view band rows, and presents the editable band configuration in a Windows Forms grid.
🔍 The user selects a Civil 3D Section View from the dialog, reviews each band row, and can adjust the band location, band style, and linked section data sources. This is useful when multiple Civil 3D section bands need to be standardized without opening several native dialogs manually.
📊 The grid displays practical columns such as Location, Band Style Name, Section 1 Data Source, and Section 2 Data Source. The program then applies the selected configuration back to the active SectionView using Civil 3D API band set objects.
🧠 The tool is designed for Civil 3D production workflows involving SectionView, sample lines, section sources, section data bands, segment bands, styles, band sets, and drawing annotation management. It does not create sample lines or section views; its main purpose is to update the band configuration of existing Civil 3D section views.
Helper function: (if any)
- 🧰 Command registration – the plugin exposes a Civil 3D command through
CommandMethodAttribute, with the launch methodLaunchSectionBandUpdaterDialogopening the updater form. - 🔍 Initial drawing scan –
LoadInitialDrawingDatareads the activeCivilDocument, finds alignments, sample line groups, sample lines, section views, sections, and section band styles. - 📐 Section View selection logic –
cmbSectionViewslists availableSectionViewobjects, andCmbSectionViews_SelectedIndexChangedrefreshes the grid when the user changes the selected Section View. - 📊 Band grid population –
PopulateGridBandsfillsdgvBandswith editable rows representing top and bottom section view bands. - 🧩 Band source mapping – metadata objects such as
SectionBandRowMeta,SectionViewMeta, andSectionViewBandItemkeep track ofSection1Id,Section2Id,BandStyleId,SampleLineId, andSectionViewId. - 🎨 Band style loading – the plugin reads Civil 3D style collections through
CivilApplication.ActiveDocument.Styles,BandStylesRoot,SectionViewSectionDataBandStyles, andSectionViewSegmentsBandStyles. - 🔄 Top and bottom band editing – helper calls such as
GetTopBandItems,SetTopBandItems,GetBottomBandItems, andSetBottomBandItemsseparate band locations and write them back to the selected Section View. - 🔒 Transaction-safe updates – the updater uses AutoCAD database transactions with
StartTransaction,GetObject, andCommitto apply changes safely to drawing objects. - 🔴 Error reporting – failed updates are reported through message boxes such as
Error applying changes to Section ViewandDatabase Error, making troubleshooting easier for Civil 3D users.
Functionalities:
- 🚀 Open Section View Band Manager – launches a focused Civil 3D dialog for editing section view band set data.
- 🔍 List Civil 3D Section Views – scans the active drawing and lets the user choose the target
SectionView. - 📊 Review band rows in a grid – displays top and bottom band entries with location, style, and data source columns.
- 🎨 Update band styles – lets the user assign Civil 3D section view band styles from available drawing style collections.
- 📐 Change section data sources – supports editing of Section 1 and Section 2 data sources used by band rows.
- 🔄 Update top and bottom bands – applies changes to both upper and lower section view band sets.
- 🧠 Use Civil 3D object identifiers – stores and applies
ObjectIdvalues so the correct Section View, sections, sample lines, and styles are targeted. - 🔒 Database-safe modification – uses AutoCAD transaction logic to reduce the risk of partial drawing edits.
- 📝 Clear update workflow – provides
Update SelectedandCancelactions for simple user control. - ✅ Success and error feedback – confirms successful updates and reports Civil 3D database errors when a change cannot be applied.
Result:
✅ The final result is a practical AutoCAD Civil 3D productivity plugin that speeds up Section View band set editing, improves style consistency, reduces manual Civil 3D dialog work, and helps CAD users manage section view annotation data more efficiently. It is especially useful for drawings with multiple Section Views, sample line sources, band styles, and production annotation requirements.
