Layers allow organizing objects and controlling their visibility. Objects can be assigned to layers to group similar items like electrical parts. Layers can also be locked to prevent accidental modification. Quick Properties displays common object properties, making them easier to access and edit. Blocks let users reuse objects by combining them into a single item that can be inserted multiple times. Inquiry commands provide dimensional information between points, such as distance, angle, and delta measurements.

2. •Layers are use to control the visibility of objects and to
assign properties to objects. Layers can be locked to
prevent objects from being modified.
•Layers also can reduce the visual complexity of a
drawing and improve display performance by
controlling how objects are displayed or plotted. For
example, you can use layers to control the properties
and visibility of similar objects, such as electrical parts
or dimensions. Also, you can lock a layer to prevent
objects on that layer from being accidentally selected
and modified.

5. Using Quick Properties
The Quick Properties panel
displays the commonly used
properties for each object type,
thus making them easier to find
and improving access to them.
With the Quick Properties panel,
you can edit properties for a
selected object, or for all objects in
a selection.

7. • A block is one or more objects combined to create a single object.
Blocks help you reuse objects in the same drawing or in other
drawings.
To insert a block defined in the current drawing
1. Click Insert » Block.
2. In the Insert dialog box, in the Name box, select a name from a list of block
definitions.
3. If you want to use the pointing device to specify the insertion point, scale, and
rotation, select Specify On-Screen. Otherwise, enter values in the Insertion Point,
Scale, and Rotation boxes.
4. If you want the objects in the block to be inserted as individual objects instead of as
a single block, select Explode.
5. Click OK.

10. Inquiry command are to obtain information about the relation
between two specified points or multiple points; for example,
the distance between points or their angle in the XY plane.
To determine the relation between points, you can display the
1. Distance between them
2. Angle between the points in the XY plane
3. Angle of the points from the XY plane
4. Delta, or changed, X, Y, and Z distances between them
