Note: SPLINEDIT automatically converts spline-fit polylines to splines even if you immediately exit SPLINEDIT after selecting the spline-fit polyline.The data that defines a spline is represented in one of two formats: as a control frame or as fit points. The format can change depending on how the spline was orginally created, the options selected from the grip menus, or the options used in SPLINEDIT.You can change any of following data:. Control frame data consists of control vertices, the polynomial degree of the spline, and the weights assigned to each control vertex. Fit data consists of fit points, knot parameterization, the fit tolerance, and the tangents at the endpoints of the spline. Close/OpenOne of the following options displays, depending on whether the selected spline is open or closed.

An open spline has two endpoints, while a closed spline forms a loop.CloseCloses an open spline by defining the last point to be coincident with the first. By default, closed splines are periodic, maintaining curvature continuity (C2) along the entire curve.OpenOpens a closed spline by removing the final curve segment between the first and last points specified when the spline was originally created. Fit DataEdits fit point data using the following options:AddAdds fit points to the spline.After selecting a fit point, specify a new fit point to be added to the spline in the direction of the next fit point, which is automatically highlighted.If you select the last fit point on an open spline, the new fit point is added to the end of the spline.If you select the first fit point on an open spline, you have the option of specifying whether the new fit point is added before or after the first point.

New Location. Moves the selected fit point to the specified location. Specifies the next fit point.

Previous. Specifies the previous fit point. Select point. Specifies any fit point on the spline.PurgeReplaces the fit data from the spline with control vertices.TangentsChanges the starting and ending tangents of a spline. Specify a point to establish a tangent direction. You can use object snaps such as Perpendicular or Parallel. Specify tangent.

(Available for closed splines) Specifies a new tangent direction at the point of closure. System default. Calculates the default end tangents.ToleranceRefits the spline to the existing fit points using the new tolerance value.

Edit VertexEdits control frame data using the following options:AddAdds a new control vertex at the point you specify that is located between two existing control vertices.DeleteRemoves a selected control vertex.Elevate OrderIncreases the polynomial order (degree plus one) of the spline. This results in increasing the number of control vertices across the spline.The maximum value is 26.MoveRelocates a selected control vertex.

New Location. Next. Previous. Select PointWeightChanges the weight of a specified control vertex. New weight. Recalculates the spline based on the new weight value for the specified control vertex. A larger value pulls the spline closer to the control vertex.ExitReturns to the previous prompt.
