    Bounding Lines
    1. Select bounding lines.
    2. Click Split on the guide bar.

Tip: Draw lines that are perpendicular or tangent to other lines by snapping to predefined points such as end, middle, center, and intersection points. You can also snap to points along the x, y, and z axis.
Note: The .gif shown in the image above is displayed when you select surfaces as the entity selection. You will see a different .gif file depending on which entity and which split option you select.
