Index of convenience of layers is the full freedom of relocation and copying of nested layers, groups and objects from one layer on another. For this purpose it is possible to use commands of a clipboard information Clipboard — Cut to (Cut), Copy to (Copy), Paste to (Paste) menu Edit (Editing).
At usage of command Paste to (Paste) the object which is in a clipboard, always is located on the active layer without dependence from from what layer it has been copied or moved to a clipboard. The object is allocated on center and in the uppermost position in "pile" of objects on a layer or in group.
Command Paste in Front (to Paste forward) menu Edit (Editing) allows to allocate object in home position (i.e. with saving of a location of object on an initial layer) over uppermost of the selected objects. Command Paste in Back (to Paste back) the same menu allows to allocate object in home position under lowermost of the selected objects. If the selected objects are included into group the object pasted by means of these two commands, also is located in group.
If it is required to return by all means objects on the same layer, whence they have been copied or moved to a clipboard, it is necessary to activate command Paste Remembers Layers (to Paste on former layers) the palette menu. It provides "storage saving" at object and if such layer does not exist any more "in the nature" it will be recreated with former parameters.
To move objects it is possible and by means of palettes Layers (Layers). At selection on a layer of any objects in a line of a layer in a palette with a name of this layer or group there is a small square coinciding on color with conditional "color" of a layer. Relocation of this small square for a new line

Entails also relocation of objects (fig. 10.8). If at small square relocation to retain pushed a key [Alt] objects will be copied.
To move objects it is possible and on that layer which "is invisible".
The fixed layer generally does not admit changes but if to retain pushed a key [Ctrl] it is possible to move objects and on the fixed layer.
Change of the order of layers
By means of change of the order of layers it is possible to manipulate the big masses of objects simply enough. Simple action for this purpose is required: in a palette to capture a line of the selected layer even if it is fixed or invisible", and to"drag"it above or more low in"pile"of layers. It is necessary to be guided by position of following elements:
 |
Two lines with arrows on edges (fig. 10.9): at mouse button release the moved layer occupies position between layers; |
|
Triangular arrow (fig. 10.10): at mouse button release the moved layer is allocated on this layer. |
By means of command Reverse Order (the Reverse order) the palette menu it is possible to change the order of layout of the selected layers, groups in vertical "pile". Objects change the order within that layer on which they are allocated.
 |
Nota Bene. If in the document there are objects in masking group at an imperative need to change the order of layers with the objects entering into a mask, it is necessary to pay special attention on layout of objects and to take steps on saving of a mask or on its regrouping. |

Everything that is created, it is possible to delete sometime. Layers, groups and ' objects not an exception. The layer selected in a palette, and together with it both all groups and the objects, the group selected in a palette, and together with it and the objects, the separate selected objects are deleted one of following methods.
|
Click on button Trash (Basket) ( ) in the lower part of a palette. |
|
Towage of a line with a layer name on button Trash (Basket) (). |
|
Performance commands Delete <name> to (Delete) the menu palettes Layers (Layers). |
Certainly, it is quite good before removal of a layer or group to look at their contents (for example, disconnecting all remaining) and to be convinced that on this layer or in this group does not remain the useful objects. Care at removal saves nerves and time.
Fixation of layers, groups and objects
In Adobe Illustrator program it is possible to fix not only separate objects (for what command Lock, in particular, is intended (to Fix) menu Object (Object)), but also the whole groups and layers. The fixed layer represents "indestructible whole": objects on such layer are not selected, do not change, are not moved and are not deleted.
To fix a layer or group, it is enough to click on the button allocated more to the left of a name of a layer or group. The character of the fixed layer is "замочек" (fig. 10.11) (
) in a line of a layer or group in palette Layers (Layers). Besides, the cursor of drawing tools becomes "the crossed pencil" (
).
Repeated click on the button (with "замочком") removes fixing.
To fulfill the same operation it is possible and by means of dialog box Layer Options (layer Parameters), installing or deleting flag Lock to (Fix).
 |
| Rice 10.11. The icon "замочек" symbolizes the fixed layer |
If some layers are fixed, for their simultaneous "clearing" it is necessary to execute command Unlock All (to Release all layers) the palette menu.
If it is necessary to fix all layers, except one, it is enough to click in line on the button of fixation of the given layer at a pushed key [Alt].
Temporal removal of layers from the screen
The fixed layer, group or object are reflected in the screen. However there can be a necessity to cancel display of any layers, groups or objects (fixed or unstable) on the screen. Temporarily to delete a layer from the screen, it is possible to use in several ways.
|
To click on the button with the character of "eyes" in a line of a layer, group or object in palette Layers (Layers) (fig. 10.12). Together with disappearance of the character of "eyes" objects of a layer or group or separate object cease to be displayed on the screen. The latent layer, group or separate object do not give possibility of any editing. Repeated click on this button again displays objects of a layer, group or separate object. |
|
To fulfill the same operation it is possible and by means of dialog box Layer Options (layer Parameters) in which it is necessary to remove flag Show to (Show). The subsequent setting of this flag again returns objects of a layer, group or separate object on the screen. |
If some layers are hidden, for their simultaneous "display" it is necessary to execute command Show All Layers (to Show all layers) the palette menu.
If it is necessary to hide all layers, except one, it is enough to click on the appropriate button in a line of a layer at a pushed key [Alt] or, selecting it, to execute command Hide Others (to Hide remaining) the palette menu.

Command Outline (Key line mode) of menu View (Review) forces all objects of the document to be displayed on the screen in a planimetric type. However it is necessary to mean that this mode can be used with each separate layer.
For this purpose it is necessary [Ctrl] to click with a pushed key on the button with the character of "eyes", or in dialog box Layer Options (layer Parameters) to delete flag Preview (Illustration). The character of this mode is "the eye without a pupil" (hollow eye icon) (fig. 10.13).

If it is necessary to display in a key line mode all layers, except selected, it is enough to click on one of buttons at pushed keys [Alt] + [Ctrl].
Determination of "color" of a layer
Each layer can appropriate the conditional color by which mathematical (wire) circuits and reference points are displayed that allows to understand a mash of the objects allocated on various layers easily. These colors have no influence on actually image.
By default the first layer is designated by the light blue color, the second — red, and etc., through nine layers the color palette repeats.
To use for a layer designation own color, it is necessary in palette Layers (Layers) twice to click on a line of the necessary layer e in appeared dialog box Layer Options (layer Parameters) in list Color (Colour) to select one of colors - offered by the program
If any color does not approach or does not arrange the user at a choice of variant Other (Another) on the screen is deduced dialog box Color (Colour) in which it is possible to define any especial color.
|
Nota Bene. It is necessary to mean only. That this color displays thin enough lines, therefore, that them to distinguish, contrast colors are necessary rather. |
