dsh-noBS-CAD-step: Converting 2D Flat Engineering Drawings into noBS CAD Scripts and STEP Files

`dsh-noBS-CAD-step` is a plugin for DeepSeek Harness (DSH) that uses the noBS CAD engine to automatically convert 2D flat sheet drawings into 3D models and STEP files. The plugin includes a core Skill covering workflows such as sheet material lists and hole position recognition, along with five tools that support script execution, file checking, print probing, and view overlay. It provides visual operation through a Web UI panel and is cross-platform without requiring additional dependencies. The plugin only recognizes vertical cylindrical holes, and its accuracy depends on the quality of the printed material itself. Overall, it offers developers an automated drawing-processing solution without complex environment setup.
