 # ExportDXF
 
-A Windows desktop application that automates exporting flat pattern DXF files from SolidWorks drawings, assemblies, and parts. Built for sheet metal fabrication workflows, it extracts BOM data, generates DXF flat patterns with etch/bend line markings, and exports everything to a local folder with an Excel workbook for downstream tools like [OpenNest](https://github.com/ajisaacs/OpenNest).
+A Windows desktop application that automates exporting flat pattern DXF files from SolidWorks drawings, assemblies, and parts. Built for sheet metal fabrication workflows, it extracts BOM data, generates DXF flat patterns with etch/bend line markings, and exports drawing PDFs to a local output folder with SQL Server tracking.
 
 ## Features
 
 - **Batch DXF export** from SolidWorks drawings, assemblies, or individual parts
 - **Flat pattern generation** with automatic sheet metal detection
-- **Etch line insertion** on bend-up lines for fabrication reference (via EtchBendLines/ACadSharp)
+- **Etch line insertion** on bend-up lines for fabrication reference (via EtchBendLines library)
 - **PDF export** of SolidWorks drawings
-- **Excel BOM output** -- generates an xlsx workbook with a BOM sheet (direct copy of the SolidWorks BOM table) and a Cut Templates sheet (DXF filenames, thicknesses, K-factors, bend radii, content hashes)
-- **Revision tracking** -- content hashing detects unchanged DXFs across re-exports; changed files get revision suffixes (e.g., `PT03 Rev2.dxf`)
-- **Configurable filename template** -- format like `4321 A01 PT{item_no:2}` with placeholders for item number, part name, configuration, and material
-- **Pluggable drawing info extraction** -- auto-fills the filename template from the document name; extensible via `IDrawingInfoExtractor`
+- **Local file export** -- saves DXFs and PDFs to a configurable output folder
+- **SQL Server database** -- tracks export history and BOM data via Entity Framework Core
 - **View flip control** with automatic, manual, and prefer-up strategies
-- **Active document tracking** -- connects to SolidWorks and updates the UI when the active document changes
-- **Per-export and app-level logging** to plain text log files
+- **Active document tracking** -- connects to SolidWorks and displays the active document in the title bar
+- **BOM extraction** from drawing BOM tables or assembly component trees
+- **Drawing history dropdowns** -- equipment and drawing number filters populated from past exports
 
 ## Requirements
 
 - Windows 10/11
 - .NET 8.0
 - SolidWorks (installed and licensed)
+- SQL Server (default: `localhost`, database: `ExportDxfDb`, Windows auth)
 
 ## Solution Structure
 
 ```
 ExportDXF.sln
   ExportDXF/          Main WinForms application
-  EtchBendLines/      Library for adding etch lines to DXF files (git submodule, uses ACadSharp)
+  EtchBendLines/      Library for adding etch lines to DXF files (git submodule)
+    netDxf/           DXF file read/write library

 ## How It Works
 
-1. **Startup** -- Connects to a running SolidWorks instance (or launches one). Auto-fills the filename template from the active document name using pluggable extractors.
+1. **Startup** -- Connects to a running SolidWorks instance (or launches one) asynchronously. Loads past export history from the database to populate equipment/drawing dropdowns. Displays the active SolidWorks document name in the title bar.
 
 2. **Export** -- Based on the active document type:
-   - **Drawing**: Copies the raw BOM table to the Excel BOM sheet, exports the drawing as PDF, then generates flat pattern DXFs for each sheet metal component.
+   - **Drawing**: Extracts BOM items from BOM tables, exports the drawing as PDF, then iterates through each component to generate flat pattern DXFs.
    - **Assembly**: Extracts components from the assembly tree and generates flat pattern DXFs for each sheet metal part.
    - **Part**: Generates a single flat pattern DXF for the active part.
 
-3. **Post-processing** -- Each exported DXF is run through the EtchBendLines library, which identifies bend-up lines and adds short etch marks at their endpoints on a dedicated `ETCH` layer. Only up bends are etched because SolidWorks automatically flips the flat pattern so the shortest flange is the first bend. The etch marks let the press brake operator verify part orientation right off the laser table without flipping.

Only up bends are etched because SolidWorks automatically flips the flat pattern so the shortest flange is the first bend. The etch marks let the press brake operator verify part orientation right off the laser table without flipping -- the first bend (shortest flange) will always have an etch line.
 
-4. **Save** -- DXF and PDF files are saved to a `Templates/` folder next to the source file. An Excel workbook is written with the BOM and Cut Templates sheets. If re-exporting, content hashes are compared against the existing workbook -- unchanged DXFs are skipped, changed DXFs get a revision suffix.

+# Auto-fill Equipment/Drawing from Export History
+
+## Problem
+
+When a SolidWorks file is opened that doesn't match the `DrawingInfo` regex (e.g., `Conveyor Frame.sldasm` instead of `5028 A02 Conveyor.slddrw`), the equipment and drawing number dropdowns are left empty even though the file may have been exported before with known values.
+
+## Decision
+
+- **Lookup key:** SolidWorks source file path (`ActiveDocument.FilePath`)
+- **Storage:** Query the existing `ExportRecords` table (no new table or migration)
+- **Priority:** Database lookup first; fall back to title regex parse if no history found
+
+## Design
+
+### Modify `UpdateActiveDocumentDisplay()` in `MainForm.cs`
+
+When the active document changes:
+
+1. Query the DB for the most recent `ExportRecord` where `SourceFilePath` matches `activeDoc.FilePath` (case-insensitive)
+2. If found, parse the stored `DrawingNumber` via `DrawingInfo.Parse()` and auto-fill equipment/drawing dropdowns
+3. If not found, fall back to current behavior: `DrawingInfo.Parse(activeDoc.Title)`
+
+### What doesn't change
+
+- No schema changes, no new migration
+- Equipment/drawing dropdowns still populated with historical values in `InitializeDrawingDropdowns()`
+- Export flow untouched
+
+### Error handling
+
+- DB query wrapped in try/catch so failures don't break the UI
+- Case-insensitive path comparison (Windows paths are case-insensitive)
