11.3.1. Changing the Viewing Direction
The viewing direction is established by a vector directed from the viewpoint to the display coordinate system
origin. You use the /VIEW command to define the position of the viewpoint in the display coordinate system.
Command(s): /VIEW
GUI: Utility Menu> PlotCtrls> Pan, Zoom, Rotate
Utility Menu> PlotCtrls> View Settings> Viewing Direction
You can also specify /VIEW,WN,WP to align the view perpendicular to the current working plane.
Use the following shortcut to pan, zoom, and rotate a graphics display: Press the CONTROL key and hold it
down. You are now in Dynamic Manipulation Mode. Notice that the cursor assumes a different shape. Still
holding the CONTROL key down, use the mouse buttons to manipulate your view of the display. When you
want to leave Dynamic Manipulation Mode, simply release the CONTROL key.
You can also remap your mouse buttons to match the operation (in dynamic mode only) of other programs.
The command /UIS,BORD,LEFT,MIDDLE,RIGHT can be used. See the /UIS command for more information on
dynamic mode mouse button remapping.
Note
If you are a Windows ANSYS user performing dynamic manipulation (panning, zooming, rotating),
do not use the 256-color setting, which is the default on many systems and which slows down
computer performance. To change the color setting, select the Start button in the bottom lefthand
corner of the terminal screen and choose Settings> Control Panel> Display> Settings.
Change the Color Palette drop-down list to True Color, or, at least, the 650536 value. Increase
resolution to the maximum value allowed for that setting. Also note that even though you can
now run 3-D graphics without a 3-D card, it is highly recommended that you use a 3-D accelerated
card to improve dynamic rotation and other plotting speed.
11.3.2. Rotating the Display About a Specified Axis
11.3.3. Determining the Model Coordinate System Reference Orientation
To rotate the graphics display about the screen axes or about the global Cartesian axes, use any of the following.
(The right-hand rule defines positive angular rotation about any axis.)
Command(s): /ANGLE, /XFRM
GUI: Utility Menu> PlotCtrls> Pan, Zoom, Rotate
Utility Menu> PlotCtrls> View Settings> Angle of Rotation
Utility Menu> PlotCtrls> View Settings> Rotational Center> By Pick
Utility Menu> PlotCtrls> View Settings> Rotational Center> By Location
Utility Menu> PlotCtrls> View Settings> Rotational Center> Reset to Focus Point
11.3.3. Determining the Model Coordinate System Reference Orientation
The /VUP command (Utility Menu> PlotCtrls> View Settings> Viewing Direction) determines the "starting"
orientation of your display. For instance, with the viewpoint and rotation at their default settings, /VUP,WN,X
orients the display such that the positive X axis is vertical pointing upward, Y is horizontal pointing to the
left of the screen, and Z points out of the screen.
