You can modify the size of a template component or object.
Do the following:
Template components and objects can also be reshaped (and resized) by dragging the resize handles. To do that select the component. If you hold down the Shift key while you drag, it will retain the aspect ratio. Note that dragging the handles of polylines, polygons and free form areas is the only way to resize them.
When you resize template objects, you can see the measures of the objects on the Status bar.
