You can use the Attribute Dropper to quickly copy the attributes of an object, such as stroke, pen, and fill ink, text style, transform, dimensions, transparency, Dynamic Effects, and/or SpriteEffects, and paste them onto another object.
When working with grouped objects, the Attribute Dropper will not copy the pen or fill inks. It will only copy and paste the grouped object's dimensions, transparency, and SpriteEffects.
To copy the attributes of a grouped object, select the Attribute Dropper, then select Group object as a whole in the Properties bar. Then click the target object to paste the group's attributes.
To paste the attributes of an object onto a grouped object, select the object and the Attribute Dropper. Then select Group object as a whole in the Properties bar. Click the target group to paste the object's attributes.
