Provides options for specifying the view plane by three points or along a line. When you select View > View by Points, a ribbon with two options appears.
View by 3 Points
Creates a plane based on three points you choose. This plane is parallel to the view plane, which can be thought of as the computer screen. This is the default option.
View along Line
Creates a vector based on two points (a From point and a To point). This vector is perpendicular or normal to the view plane.
