Drawing a Spline
Creo Elements/Direct Drafting allows you to draw splines in your drawing using Spline.
To draw a spline:
1. Click Drafting and then, in the Draw group, click the arrow next to 
Spline.
Spline.2. Click the required Spline button and perform the associated procedure.
Spline Button | Purpose | Procedure | ||
|---|---|---|---|---|
| Interpolation | Draw an interpolation spline using interpolation points. Points on an interpolation spline (I spline) are called interpolation points. A spline created with interpolation points passes exactly through the interpolation points used to define it. | a. Specify a sequence of interpolation points. b. Click  OK.While creating an interpolation spline, you can also change the order of spline, append the spline to an existing geometry, and specify the slope of an interpolation spline. See Modifying Splines for more information. | ||
 Control | Draw a control spline. When you draw a spline using a control polygon, the shape of the spline is influenced by the control polygon formed by the control points. | a. Specify a sequence of control points.
b. Click OK.Creo Elements/Direct Drafting draws a spline curve based on the control points you specified. While creating a control spline, you can also change the order of the spline. See Modifying Splines for more information. |
 | • To display the control polygon of an interpolation spline, click > > and then click the Vertex check box. • To display or hide the spline control points, click Drafting and then, in the Draw group, click the arrow next to Spline. Click  Display On or  Display Off to display or hide the spline control points, respectively, and then select the spline. |
