Edit Splines with SPLINEDIT
SPLINEDIT provides additional editing options, such as adding a kink to the
spline, and joining a spline to another contiguous object, such as a line, arc,
or other spline. As shown, objects are joined to splines with C0 continuity.
Edit Splines with a Palette
The Properties Inspector palette provides access to several spline parameters
and options, including the degree of the spline, the weight for each control
point, the knot parameterization method used in conjunction with fit points,
and whether the spline is closed. For more information, see
Draw Splines (page
186).
Trim, Extend, and Fillet Splines
Trimming a spline shortens it without changing the shape of the portion that
remains. Extending a spline lengthens it by adding a linear portion that is
tangent to the end of the spline (C1 continuity). If the shape of the spline is
later changed, the tangency of the linear portion is not maintained.
Trimming a spline shortens it without changing the shape of the portion that
remains.
Filleting a spline creates an arc that is tangent to the spline and the other
selected object. The spline might be extended with a linear portion to complete
the fillet operation.
