The Selection tool is active by default. When this tool is active, you can select shapes and components. Selected components can be moved, resized, and rotated. For more on using the Selection tool to manipulate components and shapes, see Manipulating Components.
The Rectangle tool creates and edits rectangle shapes. To create a rectangle, select the tool and then click and drag inside a window to create a new rectangle. Hold down Ctrl to make it a perfect square, and the Shift key to make it grow from the center point. Once a rectangle is created, you can use the square handles to change the rectangle's height and width. This is important because it is the only way to resize a rotated rectangle and let it remain a rectangle. If you resize a non-orthogonally rotated rectangle using the Selection tool, it will skew and become a parallelogram. If you double-click on the rectangle so the tool is active, you can change the rectangle's width and height using the tool-specific handles. From the toolbar, you can also change the rectangle's location (in pixels) on the window using the X and Y axes.
There are also small circle handles on the rectangle that allow you to alter the rectangle's corner rounding radius. Simply drag the circle down the side of the selected rectangle to make it a rounded rectangle. Hold down Ctrl to drag each rounding handle independently if you want non-symmetric corner rounding. You can use the Make Straight button in the rectangle's toolbar to return a rounded rectangle back to a standard, straight-corner rectangle.
The Circle tool creates and edits circles and ellipses. It is used in much the same way as the rectangle tool. While it is the active tool, you can click and drag inside a window to create a new ellipse. Hold down Ctrl to make it a perfect circle, and the Shift key to make it grow from the center point. When an ellipse is selected, use the width and height handles to alter the shape. You can also use the ellipse toolbar at the top of the Designer to change the width and the height as well as the X and Y axes.
The Polygon tool is used to create polygons and stars. Use the polygon toolbar at the top that becomes visible when this tool is active to alter the settings of the shape that is created when you drag to create a polygon. This tool can be used to make any polygon with three corners (a triangle) or more. On the Polygon menu you can specify the number of corners for the polygon. Once created, you can use the center square handle to move the polygon around, and the diamond handles to alter the size and angle of the polygon. Hold down Ctrl to keep the polygon's rotation an even multiple of 15°. For a star shape, specify the number of corners (points) and select the Star check box. A second handle that is between each corner will appear on the polygon allowing you to make a star shape.
The Arrow tool is used to create single or double-sided arrow shapes. When it is active, simply drag to create a new arrow. Use the checkbox on the arrow toolbar to choose a single or double-sided arrow. To alter the arrow, use the diamond handles to change the two ends of the arrow, and the circle handles to change the size of the shaft and the arrow head. When changing the arrow's direction, you may hold down Ctrl to snap the arrow to 15° increments.
The Pencil tool is used to draw freehand lines and shapes. When this tool is active, you can draw directly on a window by holding down the mouse button. Release the mouse button to end the path. If you stop drawing inside the small square that is placed at the shape's origin, then you will create a closed path, otherwise, you'll create an open path (line).
On the pencil toolbar, there are options for simplification and smoothing, as well as a toggle between creating straight line segments or curved line segments. The simplification parameter is a size in pixels that will be used to decrease the number of points used when creating the line. Points will be in general as far apart as this setting. If you find the line isn't accurate enough, decrease this setting. If you choose to create curved segments, then the segments between points will be Bézier curves instead of straight lines. The smoothing function controls how curvy these segments are allowed to get.
