Orientation dialog

Used to modify the settings that define various view orientations of the structure, such as Plan view, Elevation view, Perspective view, etc.

Opens when the Orientation tool is selected in the Rotation group on the View ribbon tab.

Setting	Description
View group	Isometric — This option will display the structure in default isometric view (with 70 degree Elevation angle and 330 degree Rotation Angle). An isometric view uses effectively an infinite distance to the structure. Perspective — This option will display the perspective view of the structure. The viewing distance and angles can be changed by changing one of the three options: Distance to Structure, Elevation Angle, or Rotation Angle.
Distance to Structure	This value indicates the distance of the eye (or camera) from the structure in the perspective view. You may type this value or use the spin control to increase or decrease the current value. Tip: This distance should be greater than the extents of a volume containing the structure in order to prevent distorting the view.
Elevation Angle	This value indicates the rotational angle of the eye about an axis which is lying horizontal (left to right) in the plane of the screen and passing through the center of the screen. You may type this value or use the spin control to increase or decrease the current value.
Rotation Angle	This value indicates the rotational angle of the eye about an axis which is lying horizontal (left to right) in the plane of the screen and passing through the center of the screen. You may type this value or use the spin control to increase or decrease the current value.
Spin Angle	This value indicates the rotational angle of the eye about an axis which is perpendicular to the plane of the screen (in to out) and passing through the center of the screen. You may type this value or use the spin control to increase or decrease the current value.
Default Orientation To	The orientation of the structure may be set to a view defined by one of the following options: Side — View From + X (right) Front — View From + Z (front) Plan — View From + Y (top) 3D — isometric angle (default)
Apply Immediately	Any change made through the Orientation dialog may be immediately reflected in the current view when this option is selected.
Use center of the structure as the rotational center	When this options is selected, STAAD.Pro will consider the center of the structure as the rotational center. The axis of rotation can be manually input by clearing this box and then providing the Rotational Center values.
Rotational Center	The axis of rotation can be manually input by checking this box and specifying the exact X, Y and Z coordinates in the Rotational Center boxes.
