• ChangeLayer — DCL layer picker with wildcard filter and “pick from drawing” option
• Lists only visible layers (not off, not frozen) and supports * / ? pattern matching
• Remembers the last filter via environment variable and can auto-filter based on an object’s layer

• ChangeLayerToCurrent — DCL filtered layer chooser + optional “pick layer from drawing”, then move selected objects to that layer
• Filters layer names (non-Xref only) using a substring-style match and remembers last filter + last chosen layer
• After choosing a layer, prompts for a multi-selection of objects and runs CHPROP to change their layer

• DeleteLayerByFilter — embedded DCL layer deleter with filter + multi-select, using -LAYDEL scripted sequence with VLA fallback
• v10 change: fixes the -LAYDEL command sequence to mirror manual steps: ._-LAYDEL → _N → <name> → "" → _Y (plus localized fallback)
• Excludes Xref layers and reserved layers (0, DEFPOINTS) and reports deleted vs failed

• DUPLICATELAYER / DUPLICATELAYERCURRENT — duplicate a layer’s properties into a new layer name via DCL, then set it current (optionally move the selected object).
• Copies common layer properties (Color, Linetype, Lineweight, Description) and PlotStyleName when available (STB-aware).
• DCL dialog asks for the new layer name and includes an “assign selected object” checkbox (used by DUPLICATELAYER).

• DuplicateToSelectedLayer — duplicate selected entities onto a chosen target layer via a simple DCL layer picker, then bring the copies to front and preselect them
• Remembers the last chosen layer and defaults the dialog selection accordingly
• Uses COPY with zero displacement to create duplicates in place, then CHPROP + DRAWORDER on the new entities

• FLMS3 — Model Space layer control dialog: filter + multi-select + batch actions (Freeze/Off/Lock/Plot, etc.) with optional Xref scoping
• Fixes: filters never show stray “T”; Xref layer names are displayed without the xref| prefix while operations still use full names internally
• Persists filter/toggle/xref selections between runs via environment variables

• LayerCreation — create/update a layer with True Color + Color Books support, plus a “Set as current layer” toggle (DCL with CLI fallback).
• Fields: Name, Color (ACI / RGB / ColorBook), Linetype, Lineweight, Transparency; also sets defaults for NEW objects (CELTSCALE, CETRANSPARENCY, THICKNESS).
• Runs a DCL dialog when the DCL core is healthy; otherwise runs NEWLAYERCLI (always works).

🚀 LayerList is an AutoCAD AutoLISP layer reporting utility that exports the active drawing layer table to a clean text file for Excel review, CAD auditing, and DWG quality control. It helps AutoCAD and Civil 3D users document layer names, on or off state, freeze state, lock state, color, linetype, lineweight, plot style, plottable status, and viewport default freeze settings in one fast report.

• LayersName2Clipboard — collect unique layer names from a user selection and copy them to the Windows clipboard as a newline-separated list
• Uses an HTMLFile COM object to access clipboardData and write text directly to the clipboard

• Purges unused layers using a dialog that scans the drawing and deletes layers with no entities on them.
• Protects critical layers and the current layer and optionally skips Xref layers.

• LRN — DCL-driven batch layer renamer with search filter, add prefix/suffix, remove substring, replace text, optional ALL CAPS, and optional auto-merge after remove
• Builds a matching layer list (excluding layer 0), then renames each layer via command-line -RENAME and optionally merges via -LAYMRG
• Wraps operation in an Undo mark and shows an Express Tools progress meter

• Displays a filterable layer selection dialog and then zooms the view to the extents of all objects on the chosen layer.
• Supports picking a layer directly from a selected object in the drawing and remembers the last filter used.
