example


Position continuity only. Curves have a kink at the C0 point and surfaces have a sharp crease along the C0 seam. Abutting curves and surfaces touch one another, but they have no curvature similarities.


C1 continuity

example

C2 continuity

example


Position, tangent, and curvature continuity. Curves and surfaces are perfectly smooth, and the curvature at the joint between two abutting curves or surfaces is equal. Consequently, the joint is seamless and invisible.

Datum Planes represent infinitely thin flat planes that extend infinitely in two perpendicular directions.

For display purpose a rectangular outline is shown. By default datum planes resize to the size of the model. They can be redefined to a specific size or linked to the size of a feature.

Datum planes can be used in as surfaces in some surface operations.

One side of the datum is coloured yellow and the other side is red.
