Connector and callout lines


You can draw connector lines between objects. Objects stay connected by these lines even when you move one or both objects. Connector lines, which are also known as "flow lines", are used in technical drawings such as diagrams, flowcharts, and schematics. For information about drawing flowchart shapes, see Predefined shapes.

There are three types of connector lines that you can draw. You can draw a straight connector line. You can also draw right-angle connector lines with a sharp corner or a rounded corner. You can edit connector lines by moving, adding, or deleting segments.

Using the controls on the property bar, you can modify the width and style of a connector line as well as apply arrowheads. For more information, see Format lines and outlines. You can also change the color of connector lines.

You can choose default settings for connector lines such as snapping points and distance from the objects they are connecting.

When you move objects, their connector lines remain attached.

You can draw callout lines that label and draw attention to objects.

Examples of callouts

To use connector and callout lines with precision, you need to snap them to specific nodes in objects. For more information about snapping and snapping modes, see Snap objects.

*

Connector lines and objects attached to connector lines cannot be brought into Focus mode. For more information about Focus mode, see Edit objects in Focus mode.

To draw a connector line between two or more objects

Back to Top
1 In the toolbox, click the Connector tool button, and then on the property bar click one of the following:
Straight-line connector tool — to create a straight connector line at any angle
Right-angle connector tool — to create a connector line containing vertical and horizontal segments at right angles
Rounded right-angle connector tool — to create a connector line containing vertical and horizontal elements at rounded right angles
2 Drag from a node on one object to a node on another object.

 

You can also
Move a horizontal segment in an angled connector line
Using the Shape tool , select a connector line, and drag the middle node on the segment that you want to move.
Move an end point of an angled connector line
Using the Shape tool , drag an end node along the edge of the object.
Add a segment in an angled connector line
Using the Shape tool , drag a corner node.
Delete a segment in an angled connector line
Using the Shape tool , drag a corner node over the closest corner node.

To change the direction of a connection line

Back to Top
1 In the toolbox, click the Anchor editing tool .
2 Click the anchor point from which you want to change the connector line direction.
3 On the property bar, click the Adjust anchor direction button .
4 In the Adjust anchor direction box, type one of the following values:
0 — directs the connector line to the right
90 — directs the connector line straight up
180 — directs the connector line to the left
270 — directs the connector line straight down

*

You can change the direction of only right-angle connector lines.

To add an anchor point to an object

Back to Top
1 In the toolbox, click the Anchor editing tool .
2 Double-click anywhere on an object to add the anchor point.

*

By default, anchor points that you add to an object are not available as snap points for a connector line when the object is moved around in the drawing. To make an anchor point available as a snap point, select it with the Anchor editing tool, and click the Auto anchor button on the property bar.

By default, the position of the anchor point is calculated relative to its position on the page. You can set the anchor point position relative to the object that it is attached to, which is useful if you want to set anchor points in the same relative position in multiple objects. To set the anchor point position relative to the object, select the anchor point with the Anchor editing tool . On the property bar, click the Relative to object button , and type the coordinates in the Anchor position box.

To move or delete an anchor point

Back to Top

 

To
Do the following
Move the anchor anywhere along the perimeter of an object
Using the Anchor editing tool , drag the anchor point to another point on the perimeter.
Move the anchor to the middle of an object
Drag the anchor point to any point inside the object.
Delete an anchor
On the property bar, click the Delete anchor button .

To set a connector line to flow around objects

Back to Top
1 Using the Pick tool , select the object to which the connector line is attached.
2 Click Window Dockers Properties.
3 In the Properties docker, click Summary to display additional options.
4 Enable the Wrap connector line check box.

*

To flow around an object, a connector line must be attached to the object by at least one end.

To add a text label to a connector line

Back to Top
1 In the toolbox, click the Connector tool button, and then on the property bar click one of the following:
Straight-line connector tool
Right-angle connector tool
Rounded right-angle connector tool
2 Double-click the connector line.
A text cursor appears.
3 Type the text.

*

As you move the connector line, the text label remains attached to it.

To choose default settings for connector lines

Back to Top
1 Click Tools Options Tools.
2 In the left pane of the dialog box that appears, click Connector.
3 To limit snapping and attaching connector lines to only anchor points in objects, disable the Use geometric anchor points as snapping points check box. When this check box is enabled, you can snap and attach connector lines to edge nodes, center nodes and other geometric points in an object.
4 To increase or decrease the distance between connector lines and objects, type a higher or lower value in the Route distance from object box. This setting doesn’t apply to straight connector lines.

To draw a callout

Back to Top
1 In the toolbox, click the 2-Leg callout tool .
The 2-Leg callout tool is located on the Dimension tools flyout.
2 Click where you want the first callout segment to start, and drag to where you want the first segment to end.
3 Click where you want the second segment to end.
A text cursor is displayed at the end of the callout line, indicating where to type a label for the object.
4 Type the callout text.

 

You can also
Change the callout shape
Choose a shape from the Callout shape box on the property bar.
Change the distance between the text and the callout shape
Type a value in the Gap box.

*

If you want to edit the callout line and callout text independently of each other, as a line and a text object, you must first separate the callout line from the callout text by clicking Object Break callout apart.
