You can draw a line using the line tool or you can create lines automatically when using the quick add controls to add shapes for certain types of diagrams like flowcharts and org charts.
Using the Line Tool
The Line Tool is located in the panel left of your workspace called the SmartPanel.
The SmartPanel contains the tool palettes you'll need to create a diagram. Some are common tools used by all diagram types - like shapes, lines, and text - and some are unique to the type of diagram you're trying to draw.
To draw a line, select the type of line you want to draw from the Line Tool drop-down and click and drag your cursor in your workspace.
To draw a straight line, select Straight Line, then click and drag with your cursor in the workspace.
To draw a curved line, select Curved Line, then click and drag with your cursor.
To draw a segmented line, select Shape Connector, then click and drag with your cursor.
To draw a polygon shape, select Polygon Line, then click and drag with your cursor until a closed space is formed.
To draw a curved segmented line, select Curved Connector, then click and drag with your cursor.
To activate the line so that you may draw multiple lines in your document without re-selecting after each line, simply hold the Shift key on your keyboard while selecting your desired line. To deactivate this feature, press Esc from your keyboard.
Using the Quick Add Controls to Add Lines and Shapes
You can also quickly add common symbols connected to other symbols with lines using SmartDraw's quick add controls. Hover over a shape until you can see yellow dots appear along its perimeter. Move your cursor over any of the dots until your cursor looks like gray crosshairs, then click and draw a line in the direction you want to add a new shape. Once you're happy with your line, choose a new symbol to connect to your previous shape from the auto-prompt menu of common symbols.
This menu is intelligent and will populate with the last 6 symbols you've used in your diagram, so you'll always have the right symbols at your fingertips.
