To display or hide the control vertices and control frame, select or deselect
the spline, or use
CVSHOW (page 253) and CVHIDE (page 248).
For splines created with control vertices, you can display the control frame
by selecting the spline.
List of Prompts
The prompts that display depend on whether you create a spline with fit
points or with control vertices.
For splines created with the fit point method:
Specify first point or [Method (page 1023)/Degree (page
1026)/
Object (page 1024)]:
For splines created with the control vertices method:
Specify first point or [
Method (page 1023)/Knots (page 1025)/Ob-
ject
(page 1024)]:
First Point
Specifies the first point of the spline, either the first fit point or the first control
vertex, depending on the current method.
Method
Controls whether the spline is created with fit points or with control vertices.
(
SPLMETHOD (page 1490) system variable)
Fit Creates a degree 3 (cubic) B-spline by specifying fit points that the spline
must pass through. When the tolerance value is greater than 0, the spline
must be within the specified tolerance distance from each point.
Changing the Method updates the SPLMETHOD (page 1490) system variable.
Control Vertices Creates a spline by specifying control vertices. Use this
method to create splines of degree 1 (linear), degree 2 (quadratic), degree 3
