dsh-cad

In an AI-powered workflow, users often need to quickly glance at a DWG or DXF file to check its layer structure, pull out text annotations, or generate a preview image to share with teammates. The traditional route means launching a full CAD application and waiting for it to load. dsh-cad turns that into a single natural-language request: drop the drawing into the workspace, describe what you need, and the model resolves the right tool automatically.

Three native tools power the plugin: cad_inspect reads drawing metadata, units, bounds, layers, and block statistics; cad_extract batches text, block, or entity records with filters on layers, entity types, keywords, and more, exporting to JSON or CSV; cad_export renders an SVG or PNG preview or converts DWG to DXF, then reopens the output to validate text, entity types, and layers in a round-trip check. Every operation is strictly read-only and the source file is never modified, while multi-layer resource guards on file size, entity count, vertex count, and output bytes keep even large drawings from stalling the session, backed by worker-thread isolation and hard timeouts.

It is a fit for architects, engineers, and document curators who regularly inspect or extract data from CAD drawings, as well as anyone working inside DeepSeek Harness who wants to process drawings in conversation without switching to a dedicated CAD application.
