B-splines Contents Creating Multiple Point Splines Creating Two-Point Splines with Tangency Style Spline Support for B-Splines You can create B-Splines of 3º, 5º, or 7º with the Style Spline tool. You can adjust the smoothness of the curve by manipulating the degree of the curve. Fit Splines Use the Fit Spline tool to fit sketch segments to a spline. Fit splines are parametrically linked to underlying geometry so that changes to the geometry update the spline. Simplify Splines Use the Simplify Spline tool to reduce the number of points in a spline and to increase system performance in models with complex spline curves. Adding Tangency Control to Splines Adding Curvature Control to Splines Editing Splines: Which Method Should You Use? Editing Splines Editing Options with Two-point Splines Spline Handles A spline handle includes multiple handle types to control the weight and direction (vector) of the spline at that point. Spline Points The Insert Spline Point command adds one or more points to splines. Dimensioning to Spline Handles Use Smart Dimension (Dimensions/Relations toolbar) to dimension to spline handles. Manipulating Spline Points Splines on Surfaces Spline PropertyManager Editing Generic Splines Generic Spline PropertyManager The Generic Spline PropertyManager controls the geometry of the generic spline. Control Polygons A control polygon is a sequence of control points (nodes) in space used to manipulate an object's shape. Parent topicSplines
