A One-Point Center 3D Plan View Guidance Screen (26) Vertical Guidance Point (27) FocusIn addition to the plan and cross-section view guidance screens, there are also two optional text guidance screens available when you are using one-point center guidance. The profile view guidance screen is also available for any design type, other than a road design(.dc file).One-Point Focus 3D Guidance
The one-point focus 3D guidance method generates guidance information using a guidance plane based on a single vertical guidance point at the tip of the bucket receiving horizontal guidance.The one-point center 3D guidance method is best suited to working design surface features that are less than half a bucket width wide, or design surfaces with small features that need to be formed.

Illustration 15 shows how the guidance plane is calculated for a vertical guidance point located at the focus of the cutting edge.One-Point Focus 3D Guidance Views
Illustration 16 shows the cross section view guidance screen when the system is gathering one-point center 3D data. The displayed graphic shows a cross section of the job, at right angles to the direction of travel of the machine, and the bucket, from the point of view of the operator.Points to note in Illustration 16 are as follows:
The guidance plane is being calculated using a single vertical guidance point located at the tip of the cutting edge that has focus, as indicated by the vertical guidance point symbol on the bucket graphic.
Guidance is being generated for both bucket tips. This is indicated by the position of the 3D icon, which is displayed on both sides of the working offset value.
The right end of the bucket must move up, even though it is already above the target surface.

The two-points tips 3D guidance method generates guidance information using a guidance plane based on two vertical guidance points near the tips of the bucket.The two-points tips 3D guidance method tends to have an averaging effect on design surfaces, and is best suited to working complicated design surfaces where a smooth finish is desired.Two-Point Tips 3D Vertical Guidance Points
