IFCNet
The full IFCNet dataset currently consists of 19,000 CAD models distributed over 65 classes according to the taxonomy of the Industry Foundation Classes (IFC) standard. The IFC standard provides an open data exchange format for projects in the Architecture, Engineering and Construction (AEC) domain. Due to high imbalances with respect to the number of objects in each class, a subset of 8,000 objects from 20 classes is selected to form the IFCNetCore dataset, providing a more balanced distribution. Apart from the geometric information of the CAD model, most objects also have semantic information in the form of key-value pairs, enums or lists, which are relevant to different stages of the construction process.
