Transform a Bézier curve into a straight segment

Select the larger of the two handles at the ends of the curve; this will be the starting

point of the straight segment. After a short time the Convert to curve icon on

the Edit Points toolbar becomes active. It starts in the “in” position. Click the icon to

turn off the function. The Bézier curve segment is transformed into a straight line.

The type of the segment end point remains as it was. If all segments are straight

lines, Draw converts the object to a polygon or a polyline.

Transform complete curves, polylines and polygons

Transform a polygon or a polyline into a curve

Select the whole polygon or polyline. The object does not need to be in point mode.

Choose Convert to curve from the context menu or the Modify menu. The points in

the resulting curve are all of the type Corner point and the control points lie on the

curve segments. All the segments thus appear as straight lines.

Transform a curve into a polygon or a polyline

Select the whole curve. Choose Convert to polygon from the context menu or the

Modify menu. The curve does not need to be in point mode to do this. The individual

segments are not replaced by straight lines. Instead additional points are generated

on the curve so that the line of the polygon/polyline matches that of the curve as

closely as possible. These points are placed closer together as the curvature

increases.

Freehand lines

You can also produce a curved line from a Bézier curve using the freehand line tool

. This tool automatically inserts anchor points and control points to render the

curve as close as possible to the original Bézier curve.

Place the mouse cursor at the beginning point and keep the mouse button pressed

until you reach the end of the curve. As soon as you release the mouse button, the

curve is complete.
