In this video we will learn about the use of 'polar array' command in autocad 2016. This command is using for arranging an object in a polar manner based on a base point. You can use the associative option on/off to get more options. When you use the polar array command with associative option 'ON', the arrayed objects will be grouped as a single object. If you want to edit the array you can use the ribbon panel for the array command. You can change the object count, spacing between the objects etc in this settings.
If you are using the polar array command with associative 'OFF', you can separately select and change the objects in the array.

These commands are almost similar in all new versions of autocad.
Arraypolar:
Evenly distributes object copies in a circular pattern around a center point or axis of rotation.
This command is equivalent to the Polar option in ARRAY.
The following prompts are displayed.
Select objects:
Select the objects to use in the array.
Center point:
Specifies the point around which to distribute the array items. The axis of rotation is the Z axis of the current UCS.
Base point:
Specifies a base point for the array.
Base point:
Specifies a base point for positioning the objects in the array.
Key point:
For associative arrays, specifies a valid constraint (or key point) on the source objects to use as the base point. If you edit the source objects of the resulting array, the base point of the array remains coincident with the key point of the source objects.
Axis of rotation:
Specifies a custom axis of rotation defined by two specified points.
Associative:
Specifies whether the arrayed objects are associative or independent.
Yes:
Contains array items in a single array object, similar to a block. With an associative array, you can quickly propagate changes throughout the array by editing the properties and source objects.
No:
Creates array items as independent objects. Changes to one item do not affect the other items.
Items:
Specifies the number of items in the array using a value or expression.
Note: When defining the fill angle in an expression, the (+ or -) mathematical symbol in the resultant value does not affect the direction of the array.
Angle between:
Specifies the angle between items using a value or expression.
Fill angle:
Specifies the angle between the first and last item in the array using a value or expression.
Rows:
Specifies the number of rows in the array, the distance between them, and the incremental elevation between row.
Number of rows:
Sets the number of rows.
Distance between rows:
Specifies the distance between each row, measured from equivalent locations on each object.
Total:
Specifies the total distance between the start and end row, measured from equivalent locations on the start and end objects.
Incrementing elevation:
Sets the increasing or decreasing elevation for each subsequent row.
Expression:
Derives the value based on a mathematical formula or equation.
Levels:
Specifies the number and spacing of levels (for 3D arrays).
Number of levels:
Specifies the number of levels in the array.
Distance between levels:
Specifies the distance between the levels.
Expression:
Derives a value using a mathematical formula or equation.
Total:
Specifies the total distance between the first and last levels.
Rotate items:
Controls whether items are rotated as they are arrayed.
Exit:
Exits the command.
