Function Syntax: ManageProfileViewStyles / ManageSectionViewStyles Version: 1.0 Date: 07.06.2026 19:14:44 Version: 1.0 Date: 08.06.2026 08:57:08 Version: 1.1 Date: 07.06.2026 8:37:46PM N/A Description This project is an Autodesk Civil 3D C# .NET plugin that manages Profile View and Section View styles from a custom dark-themed Windows Forms dialog. The plugin allows the user to select existing Civil 3D Profile Views or Section Views, then apply a selected graph style, a selected band set style, or both. The main commands are ManageProfileViewStyles and ManageSectionViewStyles. The project is built as a .NET Framework plugin DLL named Civil3DProfileViewUtils.dll. The tool is useful for Civil 3D users who need to update multiple ProfileView or SectionView styles quickly without editing each view manually. Project Type🧩 C# .NET Plugin — the project builds a Civil 3D managed DLL named Civil3DProfileViewUtils.dll.🪟 Windows Forms Interface — the UI is created in code using System.Windows.Forms, not XAML or WPF.🎨 Dark Theme Dialog — the form uses custom dark background colors, styled buttons, combo boxes, check boxes, and a checked view list.📘 Documentation Included — the project includes README.md with command names, build notes, loading instructions, and project structure.🔴 Not A Standalone LISPthis uploaded project is not an AutoLISP routine and does not include a visible LSP loader file. Main Commands🚀 ManageProfileViewStyles — opens the style manager for Civil 3D Profile Views.📊 ManageSectionViewStyles — opens the style manager for Civil 3D Section Views. Loading Method🧰 Build DLL — open Civil3DProfileViewUtils.csproj in Visual Studio and build the project.📦 Load Plugin — load Civil3DProfileViewUtils.dll in Civil 3D using NETLOAD.📌 Run Command — run ManageProfileViewStyles or ManageSectionViewStyles from the Civil 3D command line.📘 Load Banner — when the DLL loads, the plugin writes a command-line message showing the available commands. User Workflow🚀 Start Command — the user runs ManageProfileViewStyles or ManageSectionViewStyles.🧩 Collect Civil 3D Data — the plugin reads available styles, band set styles, and target views from the active Civil 3D drawing.🪟 Open Dialog — the plugin opens either Profile View Style Manager or Section View Style Manager.🎨 Choose Graph Style — the user can enable Apply Graph Style and select a Profile View or Section View style.📊 Choose Band Set Style — the user can enable Apply Band Set Style and select a Profile View or Section View band set style.📌 Select Target Views — the user checks one or more views in the Target Views list.✅ Select All Option — the user can use Select and Deselect All to toggle all listed views.✔ Apply Changes — the user clicks Apply to update the selected views while keeping the dialog open.↩ Undo Last Apply — the user clicks Undo to reverse the last applied style or band set operation when possible.✅ Close With OK — the user clicks OK to close the dialog.🔴 Cancel Dialog — the user clicks Cancel to close the dialog. Functionalities🚀 Profile View Style ManagementManageProfileViewStyles lets the user apply Profile View styles and Profile View band set styles to multiple Profile Views.📊 Section View Style ManagementManageSectionViewStyles lets the user apply Section View styles and Section View band set styles to multiple Section Views.🧩 Automatic Profile View Discovery — the plugin searches Civil 3D alignments and reads Profile Views through Alignment.GetProfileViewIds.📐 Automatic Section View Discovery — the plugin searches alignments, sample line groups, sample lines, and Section Views using GetSampleLineGroupIds, GetSampleLineIds, and GetSectionViewIds.🎨 Style List Collection — the plugin reads ProfileViewStyles or SectionViewStyles from the Civil 3D style collection.📊 Band Set Style Collection — the plugin reads ProfileViewBandSetStyles or SectionViewBandSetStyles from the Civil 3D style collection.✅ Multi View Selection — the user can update many Profile Views or Section Views in one Apply operation.✔ Apply Graph Style Only — the user can enable only the graph style option and update view styles without changing bands.📊 Apply Band Set Style Only — the user can enable only the band set option and import a new band set style without changing the graph style.🧩 Apply Both Style Types — the user can update both the main view style and the band set style in one operation.↩ In Dialog Undo — the plugin records a snapshot before Apply and can reverse the last applied operation from the dialog.🔒 Document Locking — write operations are wrapped with DocumentLock before modifying the Civil 3D drawing database.🧩 Transaction Handling — view style changes and band set imports are wrapped inside AutoCAD database transactions.🔄 Drawing Regen — the plugin calls Editor.Regen after Apply or Undo so the view display updates.⚠ Validation Messages — the dialog warns the user when no style option is enabled or no target view is selected.🪟 Modal Dialog — the plugin uses Application.ShowModalDialog so the style manager stays focused during editing. Important Helper Logic🚀 Plugin BootstrapProfileViewStyleExtension.Initialize prints the load message and available commands when the plugin loads.📌 Command ClassStyleManagerCommands defines ManageProfileViewStyles and ManageSectionViewStyles.🧩 Profile View Data CollectorCollectProfileViewData collects Profile View styles, Profile View band set styles, and Profile Views found through alignments.📊 Section View Data CollectorCollectSectionViewData collects Section View styles, Section View band set styles, and Section Views found through sample line groups and sample lines.📦 Data ModelsStyleItem, ViewItem, and DrawingData store style names, ObjectIds, view names, and dialog data.↩ Snapshot ModelViewSnapshot stores the previous style ID, previous band set style ID, and flags showing what was modified.✔ Apply EngineStyleApplyEngine.Apply applies selected styles and band set styles to all checked views.↩ Undo EngineStyleApplyEngine.Undo restores the previous style and attempts to restore the previous band set style.📊 Profile Band Set ResolverResolveProfileBandSetStyleId compares current Profile View band items against available Profile View band set styles.📊 Section Band Set ResolverResolveSectionBandSetStyleId compares current Section View band items against available Section View band set styles.🔍 Band Item ComparatorBandItemsMatch compares band style ObjectIds and order between live band items and style band items.🪟 Dialog ClassStyleManagerForm builds the full dark-themed Windows Forms interface in code.✅ Apply Button HandlerBtnApply_Click validates options, collects checked views, calls the Apply engine, and updates the status label.↩ Undo Button HandlerBtnUndo_Click calls the Undo engine and updates the dialog status.🎨 UI Button FactoryMakeButton creates styled dialog buttons for Apply, Undo, OK, and Cancel. Important Code Notes📌 Command Namesthe command names are ManageProfileViewStyles and ManageSectionViewStyles.🔴 Platform Requirementthis project requires Autodesk Civil 3D because it uses CivilDocument, ProfileView, SectionView, Alignment, SampleLineGroup, SampleLine, and Civil 3D style APIs.🔴 Build Requirementthe project targets .NET Framework 4.8 and x64 and requires AutoCAD and Civil 3D managed references.🔴 Props File Requirementthe project imports a machine-specific props file from a OneDrive path. If that file is missing, the project may fail to build until the reference path is corrected.🔴 README Output Path Mismatchthe README mentions C:\B\PVU, but the visible project file redirects output to USERPROFILE\PVU. The documentation should be updated to match the actual project file.🔴 Undo Scope Notethe Undo button reverses only the last Apply operation tracked inside the open dialog session. It is not a persistent undo history after closing and reopening the dialog.🔴 Band Set Undo Limitationband set undo depends on matching current top and bottom band items against available band set styles. If no exact match is found before Apply, the previous band set may not be fully restored.🔴 No Style Filteringthe visible dialog does not include wildcard filtering or search boxes for style names, band set names, or target views.🔴 No LSP Loaderthe visible project files do not include an AutoLISP loader, so the DLL is loaded manually with NETLOAD unless a loader is created separately.🔴 No Geometry Editingthe plugin does not create or modify alignments, profiles, sample lines, corridors, surfaces, labels, or drawing geometry. It changes Profile View and Section View style assignments and band set imports. Final Result The final result is a faster Civil 3D Profile View and Section View style management workflow. The user can select multiple Profile Views or Section Views, apply graph styles, apply band set styles, update many views in one operation, and undo the last Apply operation from the same dialog. This improves productivity, reduces repetitive Civil 3D style editing, supports better drawing standardization, helps QA review, and makes ProfileView and SectionView management easier in production drawings.
