(2021, November 26th) Updated release including 15,663 CAD drawings.

(2021, August 13th) Initial release including 11,602 CAD drawings.


Access to large and diverse CAD drawings is critical for developing vector graphics and symbol related algorithms. Here, we present FloorPlanCAD, a large-scale real-world CAD drawing dataset containing over 15,000 floor plans, ranging from residential to commercial buildings. With line-grained annotations, we introduce the panoptic symbol spotting task, which requires spotting both instances of countable things and semantics of the uncountable stuff. Other tasks will be available in the future.

The rich semantic, accurate location and detailed 3D shape (middle) of windows (light blue), blind windows (blue), railings (orange) and walls (dark red) are faithfully encoded in the CAD drawings of a floor plan (left) and its south facade (right).


CAD drawings in the dataset are in the SVG format. An illustration of our FloorPlanCAD dataset.
