Change what kind of continuity a blend curve maintains with an object its constraint is attached to.
Change the continuity at the picked blend points
- Choose Curves > Blend Curve Toolbox
to show an extra floating palette containing the BlendCrv Tools tab. - Choose the continuity level from the BlendCrv Tools > Constraint Continuity
sub-menu.
Change how curvature continuity is calculated at the picked blend point
Note:
You can only change the curvature type of a constraint that is attached to an object, and has G2 or greater continuity.
- Choose the curvature type from the BlendCrv Tools > Curvature Type sub-menu:
What is the difference between parametric and geometric curvature?
Parametric curvature: align the curvature to the isoparametric direction of the surface. This type of curvature is especially useful to achieve curvature continuity with the corner of a surface.
Geometric curvature: align the curvature to the intersection of the tangent and the normal direction of the surface.
Note:
You must use geometric curvature if you want the blend curve to be planar (all points on the curve lie in the same plane).
