Editing Splines

In addition to the general editing operations available for most objects, there are additional options available for editing splines with SPLINEDIT.

• Fit Data. Edits the fit point data that defines the spline, including changing the tolerance.
• Close. Changes an open spline into a continuous, closed loop.
• Move Vertex. Moves a fit point to a new location.
• Refine. Modifies a spline definition by adding and weighting control points and elevating the order of the spline.
• Reverse. Changes the direction of the spline.

You also can change the tolerance of the spline. Tolerance refers to how closely the spline fits the set of fit points you specify. The lower the tolerance, the more closely the spline fits the points.

Editing Splines with Grips

When you select splines with grips turned on, AutoCAD LT grips displays on its fit points. You can use grips to modify the shape and location of the spline.

After certain operations, fit points are discarded and grips are displayed on control points instead. These operations include trimming the spline, moving the control points, and purging the fit data. If the splines control frame is turned on, grips are displayed on both the splines control points and its fit points, when available.
