Selection of objects with a mouse |
Scroll |
Perform the following actions to select objects with a mouse.
1.Move the cursor to the required object so that the cursor «catcher» capture the object. As the cursor moves over the drawing area, a dynamic search for objects is performed automatically. When an object enters the cursor’s “trap,” it is highlighted in the color set for highlighted objects. When the cursor moves away from the object, the highlight disappears, and the dynamic search resumes. Dynamic search can be disabled in the Object Search dialog.
When performing an operation, dynamic search is performed based on the types of objects used in it. As the cursor moves across the graphics area, the object of the currently required type is highlighted.
2.Click the left mouse button. The object will change the color – it will be rendered with the color set for selected objects (this color can be set, see section Edit).
To undo object selection, click the left mouse button in any place outside the object, or press <Esc>key. Selection will be undone – the object will be rendered in its regular color.
If multiple objects need to be selected, press <Shift> or <Ctrl> key and keep it pressed, clicking the left mouse button at the required objects. At the end of selection, release <Shift> (<Ctrl>) key.
You can select multiple objects another way—using a overlapping or intersecting marquee. Position the cursor in an empty space (so it doesn't touch any objects), press the left mouse button, and drag the cursor while holding the button down. A marquee will appear on the screen following the cursor.
•When you move the cursor from left to right, an enclosing marquee is formed. It is displayed in a solid line and is filled with blue color. After releasing the mouse button, only the objects that got fully into the marquee will be selected.
•When you move the cursor from right to left, a cutting marquee is formed. It is displayed in dashed line and is filled with light-green color. After releasing the mouse button, only the objects that got fully or partly into the marquee will be selected (i.e. Intersected with the marquee).
To invert selection, specify objects separately or with a marquee, keeping <Ctrl>key pressed.
|
You can invert highlighting specific objects also with <Shift>key. Group indication of objects with <Shift> key pressed ads them to the highlighted objects. |
Sometimes, objects which need to be selected are positioned closely to one another or are even overlaid one upon another. At the same time it is difficult (and sometimes impossible at all) to specify one of them precisely with a cursor.
To select any of the closely placed objects (including those overlaid one upon another), use the Picking Over command (see Section Picking Over).
