Randomize + Rotation

Randomini Tool Operation

Illustrator Location: Advanced Toolbar > Randomini Tool

When one or more art objects are selected and the Randomini tool is in use, its widget will appear, initially centered over the bounds of the selected art (it may later be repositioned; see below). By using the cursor to click or drag parts of the widget, the artwork can be edited. Except for Hue, all changes are previewed using outlines and are not actually applied to the art until the Apply button is clicked or the Enter key is pressed. Therefore, if you change your mind and decide not to randomize the art, simply switch to another tool and the art will remain as it was. All parameters are retained between uses of the tool. When not over a widget control, the cursor for the Randomini tool has the shape of a die showing various random faces. When nothing is selected, the Randomini tool can be dragged to marquee-select artwork.

1. Rotation arm and control

Dragging the rotation control changes the angle up to which each piece of art will be randomly rotated around its bounding box center, in either a clockwise or counterclockwise direction. For example, setting the rotation arm at a 24° angle will cause the preview art to be rotated anywhere from -24° to 24°:

The rotation control may be double-clicked to set the rotation value numerically. Holding down the Shift key when dragging the control causes it to be constrained to steps of 10°. Holding down Command/Ctrl while dragging it enables “Slow-Drag,” which moves the control as if all cursor movements were reduced tenfold, allowing for fine-tuning.

2. Scale slider and thumb

Dragging the scale thumb changes the value up to which each piece of art will be randomly scaled from its bounding box center. For example, setting the scale value to 150% will cause the preview art to be scaled anywhere from 100% to 150%:

The scale thumb may be double-clicked to set the scale value numerically. Holding down Shift while dragging the thumb causes the scale values to be constrained to integer values. Holding down Command/Ctrl enables “Slow-Drag”, as per the Rotation control.

3. Offset slider and thumb

Dragging the offset thumb changes the value up to which each piece of art will be randomly offset (shifted in position). For example, setting the offset value to 6pt will cause the preview art to be moved anywhere from 0 to 6 points. The offset direction is randomly chosen.

As with the scale thumb, the offset thumb may be doubleclicked to set the value numerically, Shift-dragged to constrain the value, or Command/Ctrl-dragged to enable “Show-Drag.”

4. Apply button

Clicking the Apply button applies the currently displayed random rotation, scaling and offset to the selected art, as previewed. Immediately afterwards, since the art is still selected, new random parameters will be selected and previewed, allowing you to quickly apply multiple randomizations. To automatically deselect the art after applying the randomization, hold down Shift while clicking the Apply button. Pressing the Enter key has the same effect as clicking the Apply button unless no art is selected, in which case it opens the tool preferences dialog.

5. Hue button

Clicking the Hue button immediately randomizes the hues (strokes and fills) of the selected art. Note that black (which has zero brightness) and white (which has maximum brightness) are not affected by changing the hue. Also note that grouped objects are only affected if they have a stroke or fill applied in the Appearance panel at the group level, unless the “Ignore Grouping” preference is enabled (see below). Type objects are only affected if they have a stroke or fill applied in the Appearance panel above the Characters; to change the color of individual characters, use the Randomino panel.

6. Center control

The center control may be dragged to reposition the entire widget. Doubleclicking the center control resets all parameters to their default values (i.e., no rotation, no scaling, and no offset).

Rotation Randomization

Illustrator Location: Illustrator Main Menu > Window > Astute Graphics > Randomino

Rotates the selected artwork in a random way. Note that each rotation value is applied to the artwork in its current orientation; it does not set an absolute amount of rotation (as only certain objects in Illustrator have absolute rotations).

1. Reference point selector

Determines whether the reference point (the point about which the rotation will occur) is relative to the position of the art, or at an absolute position. 

2. Relative reference point type

Selects what the reference point is relative to: the art’s bounds; the art’s first anchor point (for paths only); the art’s last anchor point (for paths only); or the artboard.

3. Relative reference point orientation

For Art Bounds and Artboard relative reference points, specifies the position of the reference point (top left, top, top right, middle left, etc).

4. Absolute reference point coordinates

The X and Y coordinates of the reference point.

5. Absolute reference point setter

Enables a tool that allows you to click at the reference point’s position. 

6. Objects/Patterns/Gradients checkboxes

Rotation can be applied to only certain attributes of the selected art. You can choose to rotate the art objects themselves, any patterns found within the art, or any gradients found within the art.
