SketchCAD converts site sketches, hand drawings, and simple floor plans into structured CAD drawings for interior design, renovation, and measurement workflows. Capture a photo or import images from your library. SketchCAD detects walls, doors, windows, rooms, dimensions, text, and common symbols, then presents the result as editable CAD layers. Key features: • Camera and photo-library import • Multi-image stitching and batch processing • Capture quality checks and practical retake guidance • Wall, opening, room, and dimension detection • Layered CAD preview and manual corrections • Room-name, annotation, and symbol editing • On-device DXF generation and sharing • Project history, workspaces, and device recovery • Conversion completion notifications and in-app feedback Free recognition credits are included for new installations. AI recognition requires an internet connection. Project viewing, manual editing, and on-device DXF generation remain available locally. ## Key features - Sketch to CAD conversion - Photo to CAD conversion - Geometric vectorization - AI-powered inference (rooms, doors, windows) - Manual correction tools - DXF export - Sharing support ## Recent user reviews (2 of 2) All indexed reviews: https://appshunter.io/ios/app/zhuxian-cad/id6764079559/reviews.md ### 2/5 — 没有免费体验，直接付费？ *2026-09-04* 谁知道质量如何啊！ **Developer response:** 您好，抱歉让您误以为需要先付费。筑线首次安装提供 3 次免费 AI 识别，无需登录或付款；付费版用于解锁编辑、批量、导出和工作区等专业功能。您可以先在首页选择一张草图或户型图，点击“生成 CAD”体验识别效果。若未看到免费次数，请通过“App 支持”提交截图和设备信息，我们会尽快协助排查。 ### 1/5 — 最垃圾的app *2026-06-16* 毫无卵用，不明所以的一款软件 **Developer response:** 很抱歉早期版本没有清楚呈现使用流程。筑线现已支持拍照或相册导入、AI 识别墙体门窗、手动校正和 DXF 导出，并新增文字与语音生成 CAD。欢迎更新后再次体验，如遇具体问题可通过 App 内反馈联系我们，我们会持续改进。 ## Frequently asked questions about Zhuxian CAD ### How does BuildLine convert sketches to CAD?
