Graphical View Navigation
The graphical view provides a three-dimensional rendered view of everything in your job. To take advantage of this realistic view of your data, it’s important to navigate through it. Much like looking at the world through a camera lens, SA offers similar navigation controls.
Zoom. Its possible to zoom in or out. This can be accomplished by:
-
Hold down Ct r key and click-drag the mouse up or down
-
Scroll the mouse wheel up/down
-
Press the PgUp/PgDn keys
-
You can also zoom in on a region by holding down the left mouse button, click-drag the mouse to define a rectangle, and release the mouse button. The view will zoom into the defined region.
Autoscale Autoscale will zoom and center the view so that all visible objects are displayed in the graphical view at once.
Pan The view can be shifted from one side to another without zooming or rotating. This can be accomplished by:
-
Click and hold down the middle mouse button and drag in the graphical view.
-
Hold down the Shift key and then Left -click and drag the mouse in the graphical view.
-
Use the keyboard arrow keys (Up, Down, Left, and Right)
To Center the View on a Point Middle-click anywhere in the graphical view.
Rotate The view can be rotated as follows:
-
Click and hold down the right mouse button and drag in the graphical view.
View Rotation Center. Defines a pivot point for view rotations.
Selections include the following:
-
Default Automatic Rotation Center
SA will automatically select the entity closest to the center of the graphical view to become the pivot point for rotation.
-
Custom Center Rotation
The center point is fixed in this mode. The graphics will rotate about the selected point. Click on the button to assign a new rotation center point if needed.
-
Working frame Rotation Center
The graphics will rotate about the current working frame.
To Reverse the View Rotation Sense: By default, SA uses the Front of Sphere view rotation mode. When rotating in this mode, the rotation center is considered to be at the center of a sphere, while the cursor is “stuck to” the front of the sphere and spinning it. This rotation sense can be reversed to Back of Sphere mode in the User Options Machine Configuration tab. Change the Front of Sphere Mode setting.
To Spin the View: Hold down the Ctrl key and right-click-drag the mouse. This will rotate the graphics about the view perspective. This is a great way to straighten a tilted screen for rectangular selection purposes for example.
