Dwg - Gateway

Unlocking Interoperability: The Essential Role of a DWG Gateway in Modern CAD Workflows

In the world of design, engineering, and architecture, DWG is the undisputed king of file formats. For decades, Autodesk’s native drawing format has served as the lingua franca for 2D and 3D design data. However, as software ecosystems diversify, a persistent problem remains: How do you get proprietary DWG data into non-Autodesk software without losing intelligence, layers, or metadata?

Example API surface (minimal, pragmatic)

POST /upload — accept DWG, return file token, parse summary.
GET /files/id/thumbnail?size= — return PNG/JPEG preview.
GET /files/id/svg?layout=modelspace&layers=… — return SVG or simplified geometry.
POST /files/id/export?format=pdf|dxf|ifc — enqueue conversion job.
GET /files/id/metadata — returns layers, blocks, attributes, units, extents.
POST /files/id/render-tile?z=z&x=x&y=y — tile-based raster/vector tile server.
POST /files/id/redact — returns redacted copy based on layer/block rules.

The primary report-like feature in DWGgateway is the creation of PDF documents. This allows you to share design data in a universal format [19]. Unlocking Interoperability: The Essential Role of a DWG
