To resize any element or group of elements, select it so that the bounding box appears. Click any corner of the bounding box and drag it until the shape or group of shapes is the correct size. While you’re resizing the shape, you will see a display of the dimensions of the object. If you have snap-to-grid placement enabled, objects will automatically resize to increments of 10 pixels. If you have drawing guides enabled, green lines will help you resize the shape in alignment to the edges of other objects and red lines help you resize the shape in alignment to the center of other objects.

You can also specify exact dimensions for any shape or group of shapes:

1. Select the shape or group of shapes.
2. Open the blue properties menu.
3. In the W field, define the width, in pixels.
4. In the H field, define the height, in pixels.

Certain shapes, particularly complex Network or Floorplan symbols, have a locked aspect ratio, which will affect how they resize. You can easily lock or unlock the aspect ratio for any shape:

1. Select the shape.
2. Open the blue properties menu.
3. Check or uncheck the Lock Aspect Ratio box.
