Converting a span to an arc enables you to alter the appearance of a linear or Bézier curve span within a vector.
Converting a span to an arc places one control point in the middle of the span. This can be dragged to add or reduce the degree of curvature in the arc.
To convert a span into an arc:
- Select
Vector > Node Editing or click the
Node Editing
button.
- Select a vector containing a Bézier curve or linear span. The selected vector is surrounded by a bounding box, within which you can see the spans, nodes and control points that make up the selected vector.
- Position the cursor over the Bézier curve or linear span. When the cursor changes from
to 
, right-click to display its context menu. - Select Convert Span to Arc to convert the existing span into an arc span.
For example, if you were to convert a Bézier span to an arc span you would see that one control point is positioned in the centre of the arc. You can drag the control point to create a curve.
