Client-Side AutoCAD DWG Header Parsing with SwiftWasm: In-Browser Performance Benchmark

In security-conscious engineering environments, uploading proprietary CAD drawings (DWG/DXF) to remote cloud services for version validation introduces significant data compliance risks. We conducted a performance benchmark utilizing Swift compiled to WebAssembly (via SwiftWasm) to inspect raw binary header signatures directly from DOM File blobs and ArrayBuffer slices. By slicing only the initial 6 bytes (0x00 through 0x05), the Swift WASM module instantly classifies Autodesk revisions across ...
