Object / <Enter first point>: Specify a point or enter o
The SPLINE command fits a smooth curve to a sequence of points within a specified tolerance.
Creates a spline using points you specify.
Enter point: Specify a point
Enter points until you have defined the spline curve. After you have entered two points, AutoCAD LT displays the following prompt:
Close / Fit Tolerance / <Enter point>: Specify a point, enter an option, or press ENTER
Closes the spline curve by defining the last point to be coincident with the first and making it tangent to the joint.
Enter tangent: Specify a point or press ENTER
Specify a point to define the tangent vector or use the Tangent and Perpendicular object snaps to make the spline tangent or perpendicular to existing objects.
Changes the tolerance for fitting of the current spline curve. The current spline curve is redefined such that it can fit through existing points differently, according to the new tolerance.
Enter Fit Tolerance <current>: Enter a value or press ENTER
If you set the tolerance to 0, the spline curve passes through the fit points. Entering a tolerance greater than 0 allows the spline curve to pass through the fit points within the specified tolerance.
Continuing to enter points adds additional spline curve segments until you press ENTER. Enter undo to remove the last point specified.
Enter Start Tangent: Specify a point or press ENTER
The Enter start tangent prompt specifies the tangency of the spline curve at the first point.
Enter End Tangent: Specify a point or press ENTER
The Enter End Tangent prompt specifies the tangency of the spline curve at the last point.
Converts 2D or 3D quadratic or cubic spline-fit polylines to equivalent splines and deletes the polylines.
Select objects to convert to splines:
Select objects:
Select 2D or 3D spline-fit polylines
If you specify tangency at both endpoints of the spline, you can enter a point or use the Tangent and Perpendicular object snaps to make the spline tangent or perpendicular to existing objects. If you press ENTER, AutoCAD LT calculates default tangents.
Related Commands: SPLINEDIT edits a spline object. PEDIT can edit a polyline object into a spline-fit polyline. The order of the resulting spline-fit polyline depends on the SPLINETYPE system variable.
