Introduction
Curvature analysis on CAD (Computer-Aided Design) surfaces is essential for several reasons.
- Design Evaluation: Curvature analysis allows engineers and designers to evaluate the quality and feasibility of a design. By analyzing the curvature of surfaces, they can identify potential design flaws, such as areas with excessive curvature or sharp transitions that may cause manufacturing or structural issues. Evaluating the curvature helps ensure that the design meets the desired functional and aesthetic requirements.
- Manufacturing Considerations: Curvature analysis helps in assessing the manufacturability of a design. Different manufacturing processes, such as molding, machining, or forming, have limitations on the achievable curvature. Analyzing the curvature allows engineers to identify regions that may require complex tooling or additional manufacturing steps. It helps optimize the design for efficient and cost-effective production.
- Surface Quality and Aesthetics: Curvature analysis plays a crucial role in determining the surface quality and aesthetics of a design. Unwanted variations in curvature can result in undesirable visual effects like ripples, waviness, or distortion. By analyzing the curvature, designers can ensure smooth and visually pleasing surfaces, enhancing the overall product quality and customer satisfaction.
- Functional Requirements: Curvature analysis is particularly important when designing products that interact with other components or have specific functional requirements. For example, in automotive design, the curvature of car body panels should be carefully analyzed to ensure proper aerodynamics, structural integrity, and compatibility with adjacent parts. Similarly, in consumer products like ergonomic devices or medical equipment, analyzing the curvature helps ensure comfort, usability, and proper interaction with human anatomy.
- Simulation and Analysis: Curvature information is valuable for performing simulations and analysis of CAD models. For example, in finite element analysis (FEA), curvature data can be used to determine stress concentrations, deformation patterns, and areas prone to failure. Curvature-based analysis also aids in surface fitting, reverse engineering, and geometric comparisons between different CAD models or physical objects.
Overall, curvature analysis on CAD surfaces is crucial for evaluating design feasibility, optimizing manufacturability, achieving desired aesthetics, meeting functional requirements, and performing accurate simulations. It helps ensure that the final product meets quality standards, performs as intended, and can be efficiently manufactured.

Introduction
Rotational scaling, as the name suggests, allows scaling of geometry around and axis. This can be very useful to generate geometry with circular patterns, such as fans, wheel rims etc. There is no direct way in Blender to scale a geometry around an axis. The following implementation was done using the new geometry nodes and would should work with Blender 3.0.1.
