Chapter 8 Creating and Working with Solid Model Features

An array of seats in a theater can be created in this manner. Figure 8-14 shows an example
of arraying a single seat to create multiple rows of seats. To create this array, select the
ARRAYPOLAR
command, select the fi rst seat, and use the following command sequence. fi
If needed, use the
Associative
option to create an associative array. For this example, the
default
Center point
option is used to set the center point of the array. Using this option is
suffi because the Z axis of the current UCS is parallel to the required axis of rotation. ficient
Once you defi the center axis, you can adjust the array using grips, the fine
Array Creation
ribbon tab, or the command line prompts.
Specify center point of array or [Base point/Axis of rotation]:
(Use the
Center
object
snap to pick the center point of the top arc of the first platform)
Select grip to edit array or [ASsociative/Base point/Items/Angle between/Fill angle/
ROWs/Levels/ROTate items/eXit] eXit: I↵
Enter number of items in array or [Expression] 6: 8↵
Select grip to edit array or [ASsociative/Base point/Items/Angle between/Fill angle/

Specify the angle to fill (+=ccw, –=cw) or [EXpression] 360: 80↵
Select grip to edit array or [ASsociative/Base point/Items/Angle between/Fill angle/

ARRAYPOLAR
command to create a polar array of seats
arranged in multiple rows. A—The first seat is modeled on the bottom platform. B—The
