SPLINEDIT command

Modifies the properties of a spline. Converts a spline to a polyline.

Alias: SPE

Description

Allows the modification of the fit data (fit points, fit tolerance, tangents at the endpoints and knot parametrization), vertices, the polynomial degree of the spline and the weights of each control vertex. Also allows the joining of the spline with an open 2D entity and reversing the direction of the spline.

Options within the command

Close/Open
Opens or closes the spline by adding or removing a segment between the start and endpoint.
Join
Joins the spline with an open 2D entity that shares an (coincident) endpoint with the spline.
Fit Data
Modifies the fit point data.
Add
Adds a fit point between two existing ones.
Delete
Removes fit points.
Kink
Adds a knot and fit point at the specified location on the spline which does not maintain tangent or curvature continuity at that point.
Move
Moves a fit point.
Purge
Replaces the fit data from the spline with control vertices.
Tangents
Specifies the start and end tangents.
toLerance
Refits the selected spline to the existing fit points using a new tolerance value.
Edit vertex
Edits control frame data.
Add
Adds a new control vertex at the specified point.
Delete
Removes a control vertex.
Elevate order
Increases the polynomial order of the spline (degree plus one) to increase the number of control vertices across the spline. Maximum value is 26.
Move
Relocates control vertices one by one.
Weight
Changes the weight of a specified control vertex then recalculates the spline based on the new value. Larger weights pull the spline closer to the control vertex.
convert to Polyline
Converts the spline to a polyline. The precision determines how closely the resulting polyline matches the spline.
Note: The PLINECONVERTMODE variable specifies the kind of polyline to convert to (0 – with line segments, 1 – with arc segments).
Reverse
Reverses the direction of the spline; a triangle icon appears on what was formerly the spline’s endpoint.
Undo
Undoes the previous modification.
eXit
Concludes the editing of the spline or returns to the previous prompt.
