Test data for BRS algorithm
On this page, you can find the CAD models in BREP and STEP formats which are used for the development of BRS (Blends Recognition and Suppression) algorithm.
You can find the test data online or in the data/cad/blends directory locally after you clone the repository of Analysis Situs.
