About Creating and Modifying Board Segments
You can create board segments using the tools in the Shape group on the Model tab. A board segment is any section of material in a design. You can make changes and manipulate the board features using the tools in the Engineering and Editing groups. You can also add other standard features including chamfers, holes, rounds, and solid cuts, and you can perform operations such as pattern, copy, and mirror.
