Function Syntax: SelectCreateLayerFilter / SCLF Version: 1.1 Date: 20.06.2026 6:38:54PM N/A Description 🧩 SelectCreateLayerFilter is an AutoCAD and Civil 3D AutoLISP utility designed for faster, cleaner CAD layer and drawing-management workflows. 📌 It turns the layers of selected AutoCAD objects into a reusable layer Properties Filter with wildcard search, multi-select control, clipboard export, and dialog-based review. Function Syntax 🚀 Main command: SelectCreateLayerFilter ⚡ Alias command: SCLF SEO Optimized Overview 🔎 This AutoCAD layer filter builder extracts unique layer names from selected entities and converts them into a layer Properties Filter expression. 🧱 The routine reads the entity layer from DXF group code 8 and removes duplicate layer names before opening the dialog. 🎛️ The dialog supports filter name, parent filter, wildcard pattern search, multi-select layer selection, horizontal scrolling, Select All, Select None, Undo, Copy Expression, Copy Layers, and Debug. 📋 The generated expression uses syntax like NAME=="LayerName" OR NAME=="OtherLayer" for AutoCAD layer filter creation. Primary Workflow 1️⃣ Run SCLF or SelectCreateLayerFilter. 2️⃣ Select drawing entities whose layers should become part of the filter. 3️⃣ Enter the filter name and parent filter in the Layer Filter Builder dialog. 4️⃣ Use the Pattern (*,?) field to narrow the visible layer list. 5️⃣ Select the required layers, copy/debug the expression if needed, then click Apply. Functionalities ✅ Selection-based layer discovery - collects unique layer names from the objects chosen by the user. ✅ Layer filter expression creation - builds NAME-based OR expressions for AutoCAD layer filters. ✅ Wildcard filtering - supports * and ? searches in the DCL layer list. ✅ Clipboard export - copies either the generated expression or selected layer names for documentation and troubleshooting. ✅ Registry persistence - remembers the last filter name and parent filter under LayerFilterPlus. Important Commands and Functions 🧩 ssget selects the source entities. 🧩 entget reads object data and layer names. 🧩 wcmatch performs wildcard matching. 🧩 -LAYER FILTER creates or updates the AutoCAD layer filter. 🧩 load_dialog, new_dialog, and action_tile control the DCL interface. Important Notes ⚠️ The command creates layer filters; it does not move, freeze, delete, or rename entities. ⚠️ Clipboard and registry features depend on Windows and Visual LISP ActiveX support. ⚠️ The temporary DCL file must be writable in the AutoCAD temporary folder.
