Edit Brush Dialog Box - Rotation Tab
These options let you control the rotation of objects in the brush as they follow the line.
Rotate along the line
With this option selected, the brush objects follow the curvature of the line. When deselected, all the objects have the same orientation.
Brush angle
Sets the angle of the objects.
Rotation changes by:
Adding
Gives an increasing rotation angle between objects by adding the value to the previous angle For example 10% increases the angle by 10% of the original value. For example, if the original value is 30 degrees, following angles are 33º (10% of 30º), 36º, 39º and so on.
Random
Gives a random rotation between objects. The slider limits the rotation; for example, 50-200% limits the rotation to between 50% to 200% of the original value.
Randomize
Generate a new random set of angles. If you prefer the previous values, click Undo.
