    Formally, using the differentiable programming approach explained above, we formulate a differentiable NURBS (“NURBS-Diff”) module, which enables deep learning frameworks to integrate NURBS-based rep-resentation of B-Rep surfaces and perform CAD operations using them.
    4. CAD applications using the NURBS-Diff module The differentiable programming approach explained above is designed mainly for deep learning applications. However, we can also use the framework for standard CAD operations, such as curve fitting, surface fitting, and surface offsetting.
    We have developed a differentiable NURBS module that can be directly integrated with existing machine learning frameworks. We have developed a mathematical framework that enables both forward evaluation and backpropagation of the losses while training.
    To compare the accuracy of our NURBS-Diff module approach for offset surfaces, we computed a simpler offset by offsetting the control points along the average normal direction of the control mesh. This approach works well for surfaces with low curvature.
