You can copy styles using the Settings tree drag-and-drop capability.
You can drag items from the Settings tree, including styles, description keys, and pipe rules, into the drawing window to copy them, or you can drag them onto a drawing icon in the Settings tree.
You can copy the following items by dragging them from one drawing or drawing template to another:
To drag an item from one drawing to another, click the item or collection you want to copy, hold down the left mouse button, and drag the item to the name of destination drawing in the Settings tree. When the cursor changes to , release the mouse button to copy the item into the drawing. The item is automatically added to the correct collection in the drawing.
If the drawing already contains an item with the name of the item being copied, the Duplicate Item Name dialog box is displayed which allows you to decide how to handle the conflict.
If you drag a label style with one or more child styles from one drawing to another, only the selected style is copied into the drawing; the child styles are not copied. If you copy a child style into another drawing, the parent style is also copied.
