【ThinkDesign】Do you know this? Surface profiling "Sign of curvature"
T3Japan
Points of the Curvature Sign Command
This command calculates the product (Gaussian curvature) and sum (mean curvature) of the principal curvatures at each point on the surface and visualizes the state of the surface using color coding.
Immediate Judgment of Convexity: It allows for instant identification of whether the surface corresponds to "convex (hill)," "concave (valley)," or "saddle shape (like a horse saddle)."
Quality Check: It is ideal for confirming whether the curvature is not inverted at the seams of patches and whether unintended "gaps" or "waves" have occurred.
Mold Consideration: It helps in understanding the properties of the surface before selecting tools during processing or considering draft angles.
