Curvature discontinuity value


New member
The curvature discontinuity analysis is possible by the porcupine curvature analysis tool, and at a C2 discontinuity point, can be read two different values. Is the subtraction of them the curvature discontinuity value at the point?
If so, why the value is different from the value displayed by the smooth curve command at the point? (or the value displayed by the extract command - curvature continuity of propagation type)
