Using Segment Tool

When finished drawing a line which consists of several segments, you can transform it into a spline. The Segment Tool helps you in this operation. You are allowed to build a spline transforming one segment (a line closed between two points) after another.

To draw a spline:

1. Select the icon on the Object Toolbar.

2. Place the mouse pointer on a segment you wish to transform.

3. Using the left mouse button drag the mouse in a new position checking how the line shape is changed.

4. When you will be satisfied with a line shape, release the button. The system will fix a new spline position. Now you can transform other segments.

On the pictures below you can see the initial polyline (left) and the target spline (right), which has been got from the former by using Segment Tool to the leftmost segment.
