BookmarksC3DEntities - Civil Engineering Tools

Short description

🔖 BookmarksC3DEntities.lsp is an AutoCAD Civil 3D AutoLISP bookmark manager that lets users save selected Civil 3D entities into a searchable navigation list. The tool stores object type, object name, color, bounding-box location, handle, and user remarks so designers can quickly zoom back to important alignments, profiles, profile views, corridors, pipes, structures, COGO points, surfaces, sections, assemblies, and other Civil 3D objects.

Command:

📌 Main command: BMEntityPosC3D.
🧰 Loading method: load BookmarksC3DEntities.lsp in Autodesk Civil 3D using APPLOAD, then run BMEntityPosC3D from the command line.
🪟 The command opens a temporary DCL dialog named C3D Bookmarked Entity Positions.
📌 The user clicks Pick from drawing to select supported Civil 3D entities.
🔎 The user selects a saved bookmark and clicks Zoom to navigate back to the object location.
💾 The user can save, save as, load, or import bookmark lists using .lst files.
🎯 Target platform: Autodesk Civil 3D with AutoLISP and Visual LISP COM support through functions such as vl-load-com, vla-getboundingbox, vla-ZoomWindow, vlax-ename->vla-object, vlax-get-property, and handent.

Description:

🧠 This AutoLISP routine is designed for Civil 3D users who work in large production drawings and need a faster way to return to important design objects. Instead of manually panning and zooming around a complex model, the user can bookmark selected Civil 3D entities and later zoom back to them from a DCL dialog.

The workflow starts with the command BMEntityPosC3D. The tool opens the C3D Bookmarked Entity Positions dialog, where the user can pick objects from the drawing, view bookmarked objects in synchronized columns, filter the list, add remarks, duplicate entries, delete entries, clear the list, save the list, load a default list, or import another bookmark list.

When the user selects Civil 3D objects, the routine checks the object class name and accepts supported entities such as AeccDbAlignment, AeccDbProfile, AeccDbProfileView, AeccDbSampleLine, AeccDbFeatureLine, AeccDbCogoPoint, AeccDbCorridor, AeccDbPipe, AeccDbStructure, AeccDbNetwork, AeccDbSurfaceTin, AeccDbGraphCrossSection, AeccDbSection, AeccDbAssembly, and AeccDbSubassembly objects.

Each bookmark stores a label, bounding-box coordinates, color text, AutoCAD handle, Civil 3D object type, and remark. When the user clicks Zoom, the routine tries to find the object again by handle and refresh its bounding box. If the handle is still valid, the zoom is based on the current object extents. If the object is no longer found, the stored bounding-box values can still provide a fallback location.

This tool is useful for Civil 3D design review, corridor checking, pipe network review, profile and section navigation, surface QA, COGO point review, large drawing management, and project coordination. It does not edit ProfileView, SectionView, Alignment, labels, bands, styles, corridors, pipe networks, or point groups. Its purpose is focused on navigation, bookmarking, filtering, saving, loading, and zooming to Civil 3D entity locations.

Helper function: (if any)

📐 Bounding-box reader — bmC3d-get-bbox reads object extents with vla-getboundingbox and converts the result into point lists.
🔎 Zoom window helper — bmC3d-zoom-ll-ur uses vla-ZoomWindow to zoom the AutoCAD view to a lower-left and upper-right window.
📐 Padding window builder — bmC3d-make-window creates a padded zoom window around the bookmarked object extents.
🎨 Color name mapper — bmC3d-aci-name converts common AutoCAD ACI indexes into readable color names.
🎨 Color string builder — bmC3d-color-string reads entity color data and returns ByLayer, ByBlock, ACI color names, ACI numbers, or true-color text.
🔒 Safe property reader — bmC3d-safe-prop uses vl-catch-all-apply to read object properties without stopping the command when a property is unavailable.
🏷️ Civil 3D name resolver — bmC3d-get-name-from-obj reads Name or DisplayName from supported Civil 3D objects.
🔍 Wildcard matching — bmC3d-wild-match performs case-insensitive filtering with wildcard patterns through wcmatch.
🔐 Supported object validator — bmC3d-supported-p checks Civil 3D object class names and keeps only supported object types.
🧩 Group mapping — bmC3d-map-group maps Civil 3D class names into user-friendly groups such as Alignments, Profiles, Profile Views, Sections, Cogo Points, Corridors, Pipes, Structures, Surfaces, and Assemblies.
📁 Default file path builder — bmC3d-file-path creates the default bookmark list path using DWGPREFIX, DWGNAME, and _BMEntityPosC3D.lst.
💾 Bookmark file writer — bmC3d-write-list-to-file writes the current bookmark list to a .lst file with prin1.
📂 Bookmark file reader — bmC3d-read-list-from-file reads a saved bookmark list from a .lst file.
📚 Group list builder — bmC3d-build-groups builds the available filter groups from the active bookmark entries.
🧩 Visible list updater — bmC3d-update-list refreshes synchronized list boxes for element type, name, color, and remark.
📌 Pick and store engine — bmC3d-pick-and-store processes the user selection, validates Civil 3D object types, reads extents and color, and appends bookmark entries.
🔎 Zoom action — bmC3d-apply-zoom zooms to the selected bookmark using a current handle-based bounding box when available.
📝 Remark editor — bmC3d-set-remark stores the user remark on the selected bookmark entry.
🧹 Delete selected bookmark — bmC3d-delete-selected removes the selected bookmark from the active list.
📋 Duplicate selected bookmark — bmC3d-duplicate-selected duplicates the selected bookmark entry directly after the original.
🪟 Runtime DCL writer — bmC3d-write-dcl creates the C3D Bookmarked Entity Positions dialog dynamically at runtime.

Functionalities:

🔖 Bookmark Civil 3D entities — the user can select supported Civil 3D objects and store them in a reusable navigation list.
🧩 Support many Civil 3D object types — the routine supports alignments, profiles, profile views, sample lines, feature lines, COGO points, corridors, pipes, structures, pipe networks, surfaces, section views, assemblies, subassemblies, and profile network parts.
📐 Store object extents — each bookmark stores the selected object bounding box so it can be used for zoom navigation.
🔎 Zoom to selected bookmark — the user can select a row and zoom directly to the bookmarked Civil 3D object location.
🔄 Refresh extents by handle — when the original entity still exists, the tool recalculates the current bounding box before zooming.
🎨 Capture object color — stored color values help identify bookmarked objects and allow color-based filtering.
🏷️ Read object names — the routine displays Civil 3D object names or display names when available.
🧩 Filter by object group — users can filter bookmarks by Civil 3D category such as Alignments, Profiles, Cogo Points, Corridors, Pipes, Structures, Surfaces, and Assemblies.
🔍 Filter by name — wildcard name filtering helps users find bookmarks in large Civil 3D drawings.
🔍 Filter by color — wildcard color filtering helps isolate bookmarked entities by stored color text.
📝 Filter by remark — custom remarks can be searched with wildcard filters for faster review workflows.
📝 Add custom remarks — the user can attach a note or description to any bookmark entry.
📋 Duplicate bookmark entries — a selected bookmark can be duplicated for repeated review workflows or list organization.
🧹 Delete selected bookmarks — unwanted bookmark rows can be removed from the active list.
🧹 Clear the full list — the entire bookmark list can be cleared from the dialog.
💾 Save bookmark lists — the current list can be saved to a drawing-based .lst file.
📁 Save bookmark lists as custom files — users can choose a custom save location for bookmark list sharing or archiving.
📂 Load drawing bookmark lists — the tool can reload the default bookmark list for the current drawing.
📥 Import bookmark lists — saved bookmark lists from other files can be imported into the active session.
🪟 Use a temporary DCL dialog — the interface is created at runtime and does not require a separate permanent DCL file.
🔴 Important limitation — this routine stores bookmark data and zoom locations only. It does not create named views or modify Civil 3D design objects.
🔴 Save limitation — bookmarks are not saved automatically when the dialog closes. The user must click Save or Save as.
🔐 Platform limitation — this script is intended for Autodesk Civil 3D and is not a general plain AutoCAD bookmark manager for all entity types.

Result:

📘 The final result is a faster Civil 3D navigation and design-review workflow. Users can bookmark important Civil 3D objects, organize them by type, filter them by name, color, or remark, add notes, save and reload bookmark lists, and zoom back to critical drawing areas with fewer manual steps. This improves productivity, reduces time spent searching large Civil 3D drawings, supports better QA review, and helps project teams manage complex Civil 3D models more efficiently.
