Step 3: Resize You Object to Desired Dimension
Now we are going to dimension our object to the size we want. Our rectangle is going to be 4.5" x 2.5". Select the dimension icon at the top of the screen and then move your cursor onto the top line of the rectangle. It will turn white. Click on it move the cursor up to place your dimension line. Enter the desired size into the box and click the green check. Repeat this for the vertical line as well. You should end up with a blue rectangle 4.5" x 2.5".
