Spline Interpolated Spline InterpolatedThe Spline Interpolated function creates splines that pass through each selected control point. To perform the function, you click wireframe snap points (or arbitrary locations) in the graphics area to define each spline point (or control point).
Spline Interpolated can also be used to create a Spline from Curves.
Spline Interpolated supports the use of the snap increment when selecting the spline control points. The snap increment allows you to get precise results when using mouse selection and helps to reduce data entry modifications.

of the Data-CAM Tree Manager.
The spline is created using only mouse selection.
1 Open the function and click to select a snap point (or anywhere in the graphics area) to select the first spline control point.
You can modify the snap increment value or turn it off while selecting control points.
2 Click to select each control point in the desired order and direction to create the spline.
3 To finish the current spline entity, press Spacebar.
