BuildCAD: 2D CAD, DWG Viewer

BuildCAD is a professional 2D CAD and BIM drafting app built for tablets, touch and stylus. Draw floor plans, elevations and construction details, open DWG and DXF drawings from desktop CAD, lay out sheets with title blocks and schedules, and export print-ready PDFs — all offline, with no account required.
