Civil Engineering Tools

• Creates a 3D offset of a selected 3D polyline.
• Converts the original 3D polyline into a temporary 2D polyline.
• Applies a user-defined offset distance.
• Reconstructs a new 3D polyline using original Z-coordinates.
• Restores system variables and cleans up temporary entities.

UnReloadDetachSelectedXrefs Xref management dialog for filtering, selecting, zooming, saving lists, loading lists, and batch operations on xrefs in the current drawing.

Sort / Purpose: Interactive Xref management tool for AutoCAD that saves, reloads, and bulk-edits Xref state via a dialog, while preserving the current UCS and view for bulk actions. • Type of tool: Dialog-driven Xref control command with filters, selection, zoom-to-xref, save/load list, and batch operations. • Scope: Works on all Xrefs in the current drawing, or only the user-selected subset (selection defaults to all). • Goal: Quickly standardize Xref configuration (Type + Found At + Units + Layer) and reapply it reliably across sessions without disrupting the user’s working context.

Purpose: Duplicate only a chosen segment of a LWPolyline between two picked points and generate it on a selected layer Supported objects: Single LWPOLYLINE only Usage style: Extract partial polyline segments and place them on a different layer using a filterable layer picker dialog

Sort / Purpose: Create a new polyline segment copied between two picked points on an existing LWPOLYLINE, place it on a chosen layer, and optionally extend, rotate, move, and generate multiple offset copies via an interactive dialog with Apply and Undo. • Scope: Works only on a selected LWPOLYLINE, extracting the portion between two points along the polyline and building a new, separate polyline from that segment. • Goal: Speed up creation of repeated pipe or band segments with controlled layer assignment, geometric extension at ends, rotation, perpendicular distance, and multiple parallel offsets using presets.

XrefLayers is a single-window tool to manage XREF insert layers: create per-XREF target layers, assign inserts to target layers, force all XREFs onto one existing layer, and zoom to a selected XREF extents.

Short description This LISP lets the user align Civil 3D pipes to chosen TIN surfaces and or profiles using elevation offsets, with a dialog that supports multi selection, live Apply preview and final OK or Cancel confirmation.

Short description
This LISP adjusts Civil 3D manhole structures so their rim elevations follow selected TIN surfaces or profiles, with elevation offsets, batch selection and a dialog that supports live Apply preview and final confirmation.

Sort / Purpose: A pipe-only shortcut command that still launches the same full UI. User may ignore manhole lists if not needed.

• Type: Shortcut alias to the master interface
• Scope: Provides access to all pipe-related elevations
• Goal: Simpler entry for users working only with pipes

Sort / Purpose: Civil 3D utility to set structure (manhole) elevations based on TIN Surfaces and/or Profiles, using a scrollable dialog with filters. • Scope: Works with AeccDbStructure and profile-view network parts, using profiles or surfaces as elevation sources, with separate offsets. • Priority: For each manhole, it tries Profiles first; if no valid profile elevation, it falls back to Surfaces.

Sort / Purpose: Civil 3D utility to set pipe invert elevations from selected TIN Surfaces and/or Profiles, using separate elevation offsets for each source and a scrollable, filterable UI for many pipes. • Scope: Works with AeccDbPipe (model), pipe profile-views, TIN Surfaces and Profiles, using wildcard filters and “Apply” inside the dialog so you can tweak/preview without closing it. • Priority: For each pipe, it tries Profiles first, then falls back to Surfaces if no valid profile elevation is found at pipe ends.

Sort / Purpose: Create a Civil 3D Structure (AeccDbStructure) at every selected COGO point, by copying a user-chosen template structure and placing the copies at each point’s location with rim set to point elevation. • Scope: Batch “stamp” manholes/inlets/etc. on COGO points. • Dependency: Uses only AeccDb COM objects (no AeccXUiPipe / AeccPipeApplication), so it avoids Civil 3D COM version issues.
