LayersNameToClipboard

Short description

📋 LayersNameToClipboard is an AutoCAD AutoLISP clipboard utility that reads the Layer property from selected objects and copies unique cleaned layer names.
🧹 It includes a simple formatting-code stripping helper and is useful for preparing layer-name lists for documentation, filters, Excel, and CAD QA workflows.

Command:

🚀 Main command: LayersNameToClipboard
🧩 Load the LSP in AutoCAD or Civil 3D, then type the command at the command line.

Description:

📋 This AutoCAD command collects selected objects, converts them to VLA objects, and reads the Layer property where available.
🧹 The StripSimpleCodes helper removes backslash-based formatting codes from text before the layer name is stored.
🔎 Duplicate layer names are ignored so the final result contains each layer only once.
📄 The layer list is converted into newline-separated text, printed in the command line, and copied to the Windows clipboard.
⚙️ Clipboard output is created through the Windows htmlfile ActiveX clipboardData interface.

Helper function: (if any)​

🧩 StripSimpleCodes removes simple AutoCAD formatting fragments such as \A1;, \C256;, and \fArial; from a text string.
🧩 C:LayersNameToClipboard runs the selection, VLA property reading, unique-list creation, clipboard copy, and command-line output.

Functionalities:

✅ Read unique layer names from selected AutoCAD objects.
✅ Use VLA object property access instead of raw DXF entity data.
✅ Check whether the selected object exposes a Layer property.
✅ Remove duplicate names from the collected list.
✅ Copy the cleaned list to the clipboard as newline-separated text.
✅ Print the number of copied unique layer names for confirmation.

Result:

✅ Unique selected-object layer names are copied to the Windows clipboard.
✅ The output can be pasted into layer filters, Excel sheets, text reports, scripts, or project documentation.

<Run>• If nothing is selected: prints </Run><Run Foreground="DarkRed">Nothing selected</Run><Run>.</Run><LineBreak/>
<Bold>Operational notes and limitations</Bold><LineBreak/>
<Run>• Clipboard support relies on Windows COM interfaces; behavior may differ in non-Windows environments.</Run><LineBreak/>
<Run>• The uniqueness check is case-sensitive because it uses </Run><Run Foreground="DarkRed">member</Run><Run> on strings; layers that differ only by case may appear separately.</Run><LineBreak/>
<Run>• The formatting stripper removes backslash-initiated segments up to the next semicolon; unusual strings without semicolons are handled by removing a short portion after the backslash.</Run><LineBreak/>
