Function Description

Rectangles, rounded rectangles, parallelograms, and diamonds are commonly used quadrilaterals. The following sections detail the drawing methods for these quadrilaterals.

Functional Entry

  • Features tab -> Objects group -> Polygon drop-down list -> Rectangle/Parallelogram.

Operation Instructions

Draw Rectangle

  • Draw a right-angle rectangle by entering coordinate values
    1. In the Objects group on the Features tab, click the Polygon drop-down button and select the Right-angle Rectangle option from the drop-down menu. A right-angle rectangle cursor appears.
    2. Move the mouse over the map. You can see the coordinate values of the current mouse position displayed in real-time in the following parameter input box. Enter the coordinate value of a point on the rectangle in the parameter input box (you can switch between the two parameter input boxes by pressing the Tab key) and press Enter to confirm the starting position of the rectangle.
    3. Move the mouse again, enter the coordinate value of the diagonally opposite point in the following parameter input box, and press Enter to complete the drawing.
    4. Right-click to cancel the current drawing operation.
  • Draw a rectangle by width and height
    1. In the Objects group on the Features tab, click the Polygon drop-down button and select the Right-angle Rectangle (Width, Height) command from the drop-down menu. A rectangle cursor appears.
    2. Move the mouse over the map. You can see the coordinate values of the current mouse position displayed in real-time in the following parameter input box. Enter the coordinate value of one vertex of the rectangle in the parameter input box (use the Tab key to switch the input focus) and press Enter to confirm the starting position of the rectangle.
    3. Move the mouse. The width and height of the rectangle are displayed in real-time on the map. Enter the width and height of the rectangle in the parameter input box and press Enter to complete the drawing.
    4. Right-click to cancel the current drawing operation.

Draw Rounded Rectangle

  1. In the Objects group on the Features tab, click the Polygon drop-down button and select the Rounded Rectangle option from the drop-down menu. A rounded rectangle cursor appears.
  2. Move the mouse over the map. As you move the mouse, the coordinate values of the current mouse position are displayed in real-time in the following parameter input box. Enter the coordinate value of a vertex of the rounded rectangle in the parameter input box (you can switch between the two input boxes by pressing the Tab key) and press Enter to confirm the starting position of the rounded rectangle.
  3. Move the mouse. The width and height of the rectangle are displayed in real-time on the map. Enter the width and height of the rectangle in the parameter input box and press Enter.
  4. Move the mouse. You can see the curvature of the four corners of the rounded rectangle changing accordingly. Enter the radius (length) for the rounded corners in the parameter input box and press Enter to complete the drawing.
    Notes:

    Entering a length of 0 or a negative value results in a right-angle rectangle. When the length is greater than half the length of the shorter side, the corner curvature no longer changes.

  5. Right-click to cancel the current drawing operation.

    The process of drawing a rounded rectangle is illustrated below:

    Enter the starting point of the rounded rectangle Enter the width and height of the rounded rectangle Enter the rounded corner radius Drawing result

Draw Parallelogram

  • Draw a parallelogram by entering coordinate values
    1. In the Objects group on the Features tab, click the Polygon drop-down button and select the Parallelogram option from the drop-down menu. A parallelogram cursor appears.
    2. Move the mouse over the map. You can see the coordinate values of the current mouse position displayed in real-time in the following parameter input box. Enter the coordinate value of one vertex of the parallelogram in the parameter input box (you can switch between the two parameter input boxes using the Tab key) and press Enter to confirm the position of the parallelogram.
    3. Move the mouse and enter the coordinate value of the second control point in the following parameter input box (you can switch between the two parameter input boxes by pressing the Tab key). Press Enter to confirm the length and direction of one side of the parallelogram.
    4. Enter the coordinate value of the next control point and press Enter to confirm the position of the third control point of the parallelogram. The parallelogram drawing is now complete.
    5. Right-click to cancel the current drawing operation.
  • Draw a parallelogram by entering length and angle
    1. In the Objects group on the Features tab, click the Polygon drop-down button and select the Parallelogram (Length, Angle) command from the drop-down menu. A parallelogram cursor appears.
    2. Move the mouse over the map. You can see the coordinate values of the current mouse position displayed in real-time in the following parameter input box. Enter the coordinate value of one vertex of the parallelogram in the parameter input box (you can switch between the two parameter input boxes using the Tab key) and press Enter to confirm the starting position of the parallelogram.
    3. Move the mouse. As you move the mouse, the length of the line connecting the mouse position to the starting point and its angle to the positive direction of the X-axis are displayed in real-time on the map. Enter the parameter values in the corresponding text boxes (you can switch between the two parameter input boxes by pressing the Tab key) and press Enter to confirm the length and angle of one side of the parallelogram.
    4. Use the same method to enter the length and angle of another side of the parallelogram, then press Enter to complete the parallelogram drawing.
    5. Right-click to cancel the current drawing operation.

Draw Diamond

  1. In the Objects group on the Features tab, click the Polygon drop-down button and select the Diamond option from the drop-down menu. A diamond cursor appears.
  2. Move the mouse over the map. You can see the coordinate values of the current mouse position displayed in real-time in the following parameter input box. Enter the coordinate value of a diamond vertex in the parameter input box (you can switch between the two parameter input boxes using the Tab key) and press Enter to confirm the starting position of the diamond.
  3. Move the mouse. As you move the mouse, the length of the line connecting the mouse position to the starting point and its angle to the positive direction of the X-axis are displayed in real-time on the map (you can switch between the two parameter input boxes by pressing the Tab key). Enter the parameter values in the corresponding text boxes and press Enter to confirm the angle of another side of the diamond. Press Enter again to complete the diamond drawing.
  4. Right-click to cancel the current drawing operation.
