The CC3D-PSE dataset (CAD Construction in 3D with Parametric Sharp Edges) is derived from the CC3D v1.0 (CAD Construction in 3D) dataset [1]. It contains 50k+ pairs of CAD models and their corresponding 3D scans. Each pair is also annotated with parametric sharp edges that were extracted from the CAD models. The parametric sharp edge annotations include three types of segments: circles, lines, and splines. The 3D objects in CC3D-PSE are unrestricted to any category, with the complexity varying from very basic to highly detailed models. The dataset can be implicitly split into  – (i) a subset of approximately 41K+ (~35K models for training ~6.3K models for testing) CAD models which has PSE as combinations of different entity types, and (ii) another subset of approximately 3K+ models (~2.4K models for training ~490 models for testing)  that has PSE as only straight line type.
