2. Place the mouse cursor over one of the handles. When the cursor becomes a double-headed arrow, drag the cursor in the direction of the arrow to modify the size of the object. If you choose a corner handle, you will resize the object along two axes at the same time. If you use a side handle, the objects will only be resized along one axis. The outline of the resulting new object appears as a dotted line.
3. Release the mouse button when the object is sized correctly. The dotted line disappears, and the resized object appears.
If the document you are working on includes many overlapping objects, editing of individual objects (which may or may not be visible) might pose a challenge. Fortunately, Draw provides a way to rearrange objects without affecting their layout.
To change the arrangement of objects:
1. In the drawing area, right-click the object you want to rearrange, point to Arrange and select the appropriate option from the Arrange list.
If time permits, ask the students to explore the other options in the Arrange list. In addition, explain which option to use under what circumstances. Specifically discuss the Behind Object option and the difference between the output from the Send to Back and Behind Object options. This is a low-priority activity.
Often, you may need to create multiple objects of the same shape and size. In Draw, you can duplicate or make multiple copies of an object. The copies can be identical or differ in size, colour, orientation and location.
To create multiple copies of an object:
1. Click the object to be copied, click Edit and select the Duplicate option. The Duplicate dialogue box opens.
2. Specify the appropriate values in the Duplicate dialogue box, and click OK to display the output in the drawing area.
Grouping and Combining Objects
When creating or editing an object, the object might be displaced from its original position. This change in location disturbs the relative position of the object to the others in the drawing. This could be critical where accuracy, in terms of position, is important such as in architectural drawings. Using Draw, you can combine drawing objects in two distinct ways, grouping and combining.
Grouping objects is like putting them into a container, where the objects are grouped with each other but retain their individual identities. You can move the group as one entity and apply changes to all the enclosed objects. A group can always be undone, and the objects that constitute the group can always be manipulated separately.
To group objects:
1. In the Drawing area, select all the objects you want to include in the group. Right click any selected object, and then select the Group option.
2. Click any object in the group; handles appear around the entire group instead of around an object. You can now modify the entire group, without applying effects to objects individually. To resize a group:
• Place the mouse cursor over one of the handles. When the cursor becomes a double-headed arrow, drag the cursor to increase or decrease the size of the objects in the group. All the objects in the group are resized equally.
You can also edit a single object in the group without breaking it. To edit individual objects in a group:
1. Double-click an object in the group. You can now enter the group and work on individual objects.
2. Click the object you want to edit; the handles appear around that object. In this mode, you can edit, add or delete this object.
3. To re-instate the group after modifying the object, double-click anywhere outside the selection frame.
You can group objects of all shapes and sizes. You can group objects in 2D, 3D or a combination of both. However, you can combine only overlapping 2D objects.
Combining drawing objects is similar to grouping, except that combining creates a permanent fusion of objects, leading to the formation of a new object. The original objects are no longer available as individual entities, and you cannot enter the group to edit the individual objects. When you combine the objects, the group takes on the properties of the lower-most object in the arrangement.
To combine objects:
1. In the drawing area, select multiple 2D objects.
The lower-most object in the following graphic is the blue object.
2. Right-click any of the objects in the selection and click the Combine option in the list. Where the objects overlap, the overlapping zone is either filled or empty, depending on the number of overlaps. When the number of overlaps is even, you get an empty space. When the number of overlaps is odd, you get a filled area.
3. After you have combined the objects, you can select the combined objects as an entity. However, you will not be able to select the empty area in the object.
To split the objects:
• In the Drawing area, right-click the combination created in the previous procedure and select the Split option from the list.
