The completed linear array
Creating a Radial Array

Array.
3 On the Options Bar, click (Radial).
4 Select the desired options, as described for creating a linear array.
TIP When you create a radial array, the steps are similar to rotating a component and copying it.
See Rotating Elements on page 379.
5 Drag the center of rotation symbol ( ) to the desired location.
The array members will be placed around an arc measured from this point. In most instances,
you want to drag the center of rotation symbol away from the center of the selected elements.
The symbol snaps to points and lines of interest, such as walls and the intersections of walls
and lines. You can also drag it onto open space.
6 Move the cursor to a position where the arc of the radial array will begin. (A line radiates from
the center of rotation symbol to the cursor position.)
NOTE If you want to specify the angle of rotation (instead of drawing it), specify an Angle value on
the Options Bar and press ENTER. Skip the remaining steps.
7 Click to position the first ray of rotation. If the cursor snaps while specifying the first ray, the
snap line rotates along with the preview box and snaps to angles on the screen while placing
the second ray.
8 Move the cursor to place the second ray of rotation.
Another line appears to indicate the ray. A temporary angular dimension appears as you rotate,
and a preview image shows the selection rotating.
9 Click to place the second ray and finish the array.
If you selected Move To 2nd on the Options Bar, the second ray of rotation defines the location
of the second member of the array. Additional array members are placed using the same spacing.
If you selected Move To Last, the second ray of rotation defines the location of the last member
of the array. Additional array members are spaced equally between the first and last members.
If you selected Group and Associate on the Options Bar, controls appear on the radial array. Use the 2 end
controls to resize the angle of the arc. Use the middle control to drag the array to a new location. Use the
top control to resize the radius of the array.
