Defines the boundaries of the view displayed in the Main view. The view cone changes as you change the viewing angle, viewing direction, eye point, and as you define motion using the motion and orientation controls.

Eye Point North

Specifies the eye point position of the view cone in relation to the north direction (Y coordinate). You can use this box to change the eye point by typing or selecting a new north coordinate.

Eye Point East

Specifies the eye point position of the view cone in relation to the east direction (X coordinate). You can use this box to change the eye point by typing or selecting a new east coordinate.

Eye Point Elevation

Specifies the height of the eye point of the view cone in relation to the model (Z coordinate). You can use this box to change the eye point by typing or selecting a new elevation.

Center Point North

Specifies the center point position of the view cone in relation to the north direction (Y coordinate). You can use this box to change the center point by typing or selecting a new north coordinate.

Center Point East

Specifies the center point position of the view cone in relation to the east direction (X coordinate). You can use this box to change the center point by typing or selecting a new east coordinate.

Center Point Elevation

Specifies the height of the center point of the view cone in relation to the model (Z coordinate). You can use this box to change the center point by typing a new elevation.

Clipping plane distances

Clipping Plane Near

Specifies the absolute distance from the eye point to the center of the near clipping plane (when Reference is set to Eye) or the location of the center point of the near clipping plane along the Reference axis (when Reference is set to North, East, or Elevation).

Clipping Plane Far

Specifies the absolute distance from the eye point to the center of the far clipping plane (when Reference is set to Eye) or the location of the center point of the far clipping plane along the Reference axis (when Reference is set to North, East, or Elevation).

The near and far clipping plane options work in conjunction with the selected Fit option in the Advanced tab of the View Settings dialog box:

  • Clear clipping distances - Sets the near and far clipping plane values to none.

  • Keep clipping distances - Uses the defined near and far clipping values for Fit operations.

  • Offset using clipping distances - Uses the defined near and far clipping values as an offset or buffer for Fit operations.

  • Auto-set clipping distances - Clears any defined near and far clipping values and uses new clipping distances set by Smart Review to automatically clip the fitted range.

For more information about the clipping distance options for Smart Review Fit operations, see Advanced Tab (View Settings Dialog Box).

Clipping Plane Reference

Displays the Reference point (if set to Eye) or the Reference axis (if set to North, East, or Elevation) for the values displayed in the Far and Near boxes.

When you select Eye from the Reference list, the Near and Far boxes display the absolute distance from the eye point to the center point of the respective clipping plane. When you select North, East, or Elevation from the Reference list, the clipping plane fields display the location on that Reference coordinate of the center point of the respective clipping plane.

For example, the eye point is at 100 feet North, -500 feet East, 200 feet Elevation and is looking straight down. You do not want to see anything above 15 feet high in the model. To accomplish this, you would select Elevation for the Reference and set Near to 15. Smart Review automatically calculates the correct clipping distance from the eye to the near clipping plane as 185 feet.

A value of none or 0 (zero) for the near and far clipping planes enables the automatic calculation of near and far clipping planes. This automatic calculation is a fast, approximate best-fit approach and it prevents clipping objects in the view while attempting to maximize rendering quality. The automatically-calculated clipping planes are displayed as the yellow lines of the view cone in the Plan and Elevation views. You can then adjust the near and/or far clipping plane values in some cases to further improve rendering quality beyond the automatic calculation.

Perspective angle

Allows you to increase or decrease the viewing area of the view cone without changing the locations of the clipping planes or the eye and center points. Move the slider anywhere from 2 degrees (to decrease area) to 160 degrees (to increase area). You can also type in the degree value. Press TAB after enter the value, and the slider bar also shows the degree setting.

Dashed

Displays the view cone in the Plan and Elevation views using dashed lines instead of solid lines. The dashed view cone allows faster updates on slow graphic cards and some notebook computers.
