Query: HybridSDF: Combining Free Form Shapes and Geometric Primitives for
  effective Shape Manipulation   CAD modeling typically involves the use of simple geometric primitives
whereas recent advances in deep-learning based 3D surface modeling have opened
new shape design avenues. Unfortunately, these advances have not yet been
accepted by the CAD community because they cannot be integrated into
engineering workflows. To remedy this, we propose a novel approach to
effectively combining geometric primitives and free-form surfaces represented
by implicit surfaces for accurate modeling that preserves interpretability,
enforces consistency, and enables easy manipulation.
