Short description

🧩 LayerImport is an AutoCAD and Civil 3D AutoLISP layer standards importer for restoring layer properties from CSV or XML files through a production-friendly DCL interface.
📥 It is designed for CAD template recovery, layer-state transfer, project standardization, and Civil 3D drawing cleanup where layer properties must be copied accurately between drawings.

Command:

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

Description:

🧩 This AutoCAD layer import tool reads external CSV or XML layer tables and applies the selected layer properties to the active DWG.
📥 The workflow supports full layer-state restoration including On/Off, Frozen, Frozen in Viewport, Locked, Plot, Colour, Linetype, Lineweight, Plot Style, and Description.
🎛️ The DCL dialog gives the user field-by-field control, so a drawing can import only colour, only linetype, only viewport freeze settings, or any selected property combination.
🔎 A wildcard layer filter using * and ? plus comma-separated OR matching helps isolate project layers before applying changes.
🧠 The tool includes undo-state snapshots so the user can apply changes, review the result, and restore the previous layer state when needed.
🗂️ Predefined folder management and DWG-name matching help automate common Civil 3D project folders and repeatable layer standards workflows.

Helper function: (if any)

🧩 LI:MakeDCL dynamically writes the embedded DCL dialog to a unique temporary file for the main import interface.
🧩 LI:ParseCSV reads CSV header and data rows, trims values, and prepares layer rows for import.
🧩 LI:ParseXML reads Layer blocks from an XML layer export format and converts them into import rows.
🧩 LI:FilterRows filters loaded layer rows by wildcard patterns using * and ? matching.
🧩 LI:SaveLayerStates and LI:RestoreLayerStates provide one-step undo for imported layer changes.
🧩 LI:ApplyRow applies selected properties to each AutoCAD layer through VLA and DXF edits.
🧩 LI:SetFrozenInVP updates the viewport-freeze bit using DXF group 70 logic.
🧩 LI:SetPlot updates the layer plot flag using DXF group 290.
🧩 LI:DoImport runs the full create/update workflow and returns the created, updated, and skipped summary.
🧩 LI:CopyToClip and LI:DebugReport copy layer names and import diagnostics to the clipboard.
🧩 LI_FOLDERS opens the predefined folder manager for adding, deleting, reordering, and saving project folder presets.

Functionalities:

✅ Import AutoCAD layer properties from CSV or XML.
✅ Create missing layers automatically when enabled.
✅ Update existing layers only when the update option is enabled.
✅ Choose exactly which layer fields are imported using property toggles.
✅ Filter import rows using * and ? wildcard patterns.
✅ Use multi-select layer lists, Select All, Select None, paging, and horizontal-scroll support for long layer names.
✅ Apply changes without closing the dialog, then use Undo to restore the previous layer state.
✅ Copy the visible layer list or debug report to the clipboard.
✅ Store settings in a support-folder configuration file and remember dialog position.
✅ Use predefined OneDrive/project folders and auto-select a folder based on the active drawing name.

Result:

✅ Selected layer properties are applied to the current AutoCAD drawing.
✅ Missing layers can be created with imported properties.
✅ Existing layer states can be updated selectively and reversed with the built-in undo snapshot.
✅ A final summary reports created, updated, and skipped layers.
