Open Segments in Corel Draw
Quick links to procedures on this page:
Drawing lines
A line is a path between two points. Lines can consist of multiple segments, and the line segments can be curved or straight. The line segments are connected by nodes, which are depicted as small squares. CorelDRAW provides various drawing tools that let you draw curved and straight lines, and lines containing both curved and straight segments.
Freehand and Polyline tools
The Freehand 
The Freehand tool lets you control the smoothness of the curved line you are drawing as well as add segments to an existing line. However, the Polyline tool is easier to use for quickly drawing a complex line that consists of alternating curved and straight segments.
In addition to drawing freehand lines and straight segments, you can use the Polyline tool to draw circular arcs.
You can choose settings to control how the Freehand and Polyline tools behave. For example, you can change the default smoothness of a curved line that you've created with these tools.
2-point line tool
You can draw straight lines by using the 2-point line tool. This tool also allows you to create straight lines that are perpendicular or tangent to objects.
Bézier and Pen tools
The Bézier 
You can draw lines with multiple segments by using the Bézier tool and clicking each time you want the line to change direction.
You can draw curves by using the Bézier tool and dragging the control handles at the ends of the Bézier curve.
B-spline tool
By using control points, you can easily shape a curved line and draw B-splines, which are typically smooth, continuous curved lines. B-splines touch the first and last control points and are pulled by the points in between. However, unlike the nodes on Bézier curves, control points don't let you specify the points through which a curve passes when you want to align a curve with other drawing elements.
The control points that touch the line are referred to as "clamped." Clamped control points function as anchors. The control points that pull the line but do not touch it are referred to as "floating." The first and last control points are always clamped on open-ended B-splines. The points in between float by default, but you can clamp points if you want to create cusps or straight lines within the B-spline. You can edit completed B-splines by using the control points.
The path of a B-spline curve is determined by the control points you set.
3-point curve tool
The 3-point curve 
You can draw a curved line by specifying its width (left), and then specifying its height and clicking the page (right).

Using nodes and control handles
Some lines have nodes and control handles that you can manipulate to shape lines as you draw. For information about node types, see Using curve objects.
Hiding the bounding box
When drawing lines by using the curve tools, you can hide the bounding box that is displayed around the lines once they are drawn. The curve tools include the Freehand tool, the 2-point line tool, the Bézier tool, the Artistic media tool, the Pen tool, the B-Spline tool, the Polyline tool, and the 3-point curve tool.
You can hide the bounding box to make drawing artistic media strokes in quick succession more fluid.
| To | Do the following |
| Draw a curved line | Click where you want to start the curved line, and drag. |
| Draw a straight line | Click where you want to start the line, and then click where you want the line to end. |
| Control the smoothness of a curved line | Type a value in the Freehand smoothing box on the property bar. Higher values produce smoother curves. |
| Reposition a line | Hold down both the left and right mouse buttons, and drag the line to a new position. |
| Place a copy of a line in the drawing | Hold down the right mouse button, and drag the line to a new position. Click Copy here. |
| Add line segments to an existing line | Click the end node of a selected line, and click where you want the new segment to end. |
| Create a closed shape from two or more connected lines | In a line that contains two segments, click the end node, and then click the start node. |
You can constrain a line created with the Freehand tool to a predefined angle, called a constrain angle, by holding down Ctrl while you drag. This feature is useful for drawing straight vertical and horizontal lines. For information about changing the constrain angle, see To change the constrain angle.
You can erase a portion of a curved freehand line by holding down Shift and dragging backward over the line before releasing the mouse button.
You can close an open object by clicking the Close curve button 
| 3 . | Hold down Alt, and move the pointer to create an arc. |
You can hold down Ctrl in conjunction with Alt to constrain the arc to 15-degree increments or another predefined angle, called a constrain angle. For information about changing the constrain angle, see Constraining objects.
This procedure cannot be used for drawing a line that is perpendicular to the baseline of a text object.
You can also drag from an existing curve to draw a perpendicular line.
Drawing perpendicular lines
The Tangential 2-point line mode can be used for drawing the sides of the cylinder.
Drawing tangent lines
| Pressing Esc cancels the line instead of finishing it. |
| You can also | |
| Reshape the line by using control points | Select the line by using the Shape tool |
| Float a control point | Select the line by using the Shape tool |
| Clamp a control point | Select the line by using the Shape tool |
| Add a control point | Select the line by using the Shape tool |
| Delete a control point | Select the line by using the Shape tool |
| Select multiple control points | Select the line by using the Shape tool |
, and reposition the control points to reshape the line. 
on the property bar.
on the property bar.
If you add to a B-spline by selecting the first or last control point, the clamped control point automatically changes to a floating control point as you draw the new portion of the line.
You can also add control points while you draw a B-spline by pressing Spacebar instead of clicking.
| 2 . | In the Workspace list of categories, click Toolbox, and then click Freehand/Bézier tool. |
| 3 . | Move the Freehand smoothing slider to set the default smoothness for curved lines. |
Double-click the Freehand or Bézier tool to display the Freehand/Bézier page in the Options dialog box.
| 2 . | Click the Bounding box button  on the property bar. |
When you hide the bounding box while working with one curve tool, the bounding box remains hidden for all curve tools. For example, if you hide the bounding box when using the Freehand tool, it remains hidden when you switch to the Bézier tool.
You can also hide the bounding box by clicking Tools
