Adding a new shape

Working with shapes
You can modify the appearance and location of shapes to fit your particular needs. Existing shapes are listed in the Drawing list in the Function pane.
To select a shape, click on the shape from the Drawing list. Doing so will highlight the shape in the image and will also open the shape settings directly below the Drawing list.
Changing the style
To change the style of a selected shape, choose the desired options in the settings and click the Apply button. In the example image above, you can either apply changes to the selected rectangle or to all rectangles.
Some settings may not be used, depending on the shape. For example, Text shapes do not use the fill color.
To set the fill color, choose the desired color and opacity from the Fill settings. The "X" box in the color drop down represents "no fill".
Changing the location and size
Reposition a selected shape by dragging it around on the image. Lines, arrows, and hollow (non-filled) shapes may be a little difficult to "grab" with the mouse. Try grabbing the lines to move them.
Resize a selected shape by dragging the handles at the edges of the shape. Text must be resized using the Label Size option in the shape settings.
Changing the drawing order
Shapes appear in the Drawing list in order that they are drawn on the image. The shape at the top of the list is on top of all other shapes. Click on the reorder icons ( and ) in the Drawing list to reorder how the shapes are drawn.
Duplicating a shape
Like a particular shape? You can make a copy by selecting the shape and then clicking the "Duplicate" button above the shape settings.
Deleting a shape
Delete a shape by clicking the delete icon () next to the shape in the Drawing list. You can delete all drawing shapes by selecting Draw > Delete all shapes from the toolbar.
