OrthoGraph 3D

OrthoGraph 3D is a free CAD tool specialized in architectural floor plan creation. Users can trace walls, windows, and doors, then extrude them into 3D. A measurement mode syncs with a phone’s AR sensor for approximate room dimensions. The software automatically calculates area and volume. It supports interior object placement like furniture. Suited for home design projects or real estate pros, OrthoGraph 3D emphasizes easy floor plan input and AR measurements without advanced architectural complexities.
