Rotating Shapes


When you create a new shape, it always starts off oriented in some way relative to the page. For example, a cylinder will always appear like this when it is created:

 

 

It is possible to rotate any shape, and there are several ways to do this.  In order to use any of them, we must first click on the shape to highlight it.

 

 

Notice the curved arrow above the shape.  Clicking once on the arrow will rotate the object 90 degrees in a clockwise direction.  Therefore, in order to rotate the cylinder 270 degrees, so that the top points towards the left, we simply click the arrow three times.

 

 

We are not constrained to multiples of 90 degrees.  By clicking and holding the mouse, and then rotating the cursor left or right, we can rotate a shape in the anticlockwise or clockwise directions respectively.  Below we see a cylinder that has been rotated 128 degrees in an anticlockwise direction.


 

Changing Dimensions

 

When you create a new shape, it always starts appears at the same size. For example, an ellipse will always appear like this when it is created:

 

 

It is possible to resize any shape, and there are several ways to do this.  In order to use any of them, we must first click on the shape to highlight it.

 

 

Notice the blue dots around the highlighting frame.  By clicking and dragging one of these dots we can resize the shape.  Sometimes we want to preserve a shape's aspect ratio (i.e. keep maintain the same ratio of heigh to width).  To do this, click and drag one of the corner dots.

 

 

Above we have enlarged the shape; it is identical to the original shape, but scaled up.  We can instead change just the height, or just the width.  We do this by dragging on one of the dots on the horizontal lines (to adjust height), or vertical lines (to adjust width).


 

Above we have adjusted just the height of the ellipse.  Now the ellipse looks like more like a circle.
