Part 1: AutoCAD Basics
Example 1: (Spline Fit)
In this example, you will create a spline using the
Spline Fit method. In this method you need to
specify various points in the graphics window. The
spline will be created passing through the specified
points.
Start a new drawing file.
Use the Line tool and create a sketch similar
to the one shown below.
Example 2: (Spline CV)
In this example, you will create a spline by using the
Spline CV method. In this method, you will specify
various points called control vertices. As you specify
the control vertices, imaginary lines are created
connecting them. The spline will be drawn tangent
to these lines.
Expand the Draw panel in the Home tab
and select the Spline CV button.
Expand the Draw panel in the Home tab
and select the Spline Fit button; the
message, “Specify first point or
[Method/Knots/Object]:” appears in the
command line.
Select the four corners of the sketch in the
same sequence as in the earlier example.
Select the lower-left corner of the sketch; the
message, “Enter next point or [start
Tangency/toLerance]:” appears in the
command line.
Select the top-left corner point of the sketch.
Similarly, select the top-right and lowerright
corners; a spline will be attached to the
pointer.
Press ENTER to create the spline.
Example 2:
Press ENTER; a spline with control vertices
will be created.
Create a polyline, as shown.
