About this app

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.

DRAFTING TOOLS
• Line, polyline, rectangle, circle, arc, spline and point
• Copy, move, rotate, mirror, offset, trim and extend
• Object snaps, polar tracking and precise keyboard input (@1000<45)
• A real command bar: type L, C, LAYER or a coordinate like desktop CAD
• Unlimited undo and redo, window and crossing selection

ARCHITECTURE & BIM
• Walls with wall types, doors and windows that cut openings automatically
• Dimensions, text, callouts, leaders and hatch patterns

DWG, DXF & IFC
• Open and save DWG (R13 to 2018) and DXF files from any desktop CAD
• Layers, blocks, dimensions and hatches round-trip with desktop CAD
• View IFC4 building models in 3D with section cuts and measurements

• Comments pinned to the drawing for review notes
• Share drawings as DWG, DXF, PDF or the native project format

WORKS OFFLINE
Your drawings stay on your device. No sign-in, no cloud upload and no data collection. Projects are plain files you can back up or move with any file manager.
