refer only to the dialog box entries. Toolbar button icons will be included in the
titles when they exist.
Beam View
Select either the 2D or 3D radio button for the desired display mode. The 2D/3D
button on the toolbar also toggles the beam display.
Note: In general, 3D displays run slower than 2D due to the amount of computations
involved with generating the wire frame.
Cursors
Choose to place cursors on either the 2D or 3D display. The cursors will appear
as two black and white dashed lines in a 2D display and as solid white lines in a
3D display. Cursor options include:
 Off – No cursors will be displayed.
 Manual – The operator manually determines the location of the cursors.
 Centroid – Cursor location is automatically drawn to pass
through the computed centroid of the beam. Note: This operation will revert to
Manual if the results window is minimized.
 Peak – Cursor location is automatically drawn to pass through the peak energy
location of the beam. Note: This operation will revert to Manual if the results
window is minimized.
There are two ways to move and position the cursors in the 2D display mode,
and only one way to move them in 3D.
Specify Cursor Location
At the bottom of the main display window are three spin controls labeled X, Y
and Z.
These controls indicate the intersection location of the cursors. Value displays
the energy at the cursor’s intersect point. In 2D mode, edit the X and Y controls
to redraw the cursors to a new location. Include the Z control when in 3D mode.
Note: The above method is the only way to move the cursors in the 3D display mode.
Drag and Drop the Cursors
The second way to move the cursors is to use the mouse to drag and drop them.
Move the mouse pointer to the intersection of the cursors. When the pointer
changes to the cursor drag symbol,
press and hold down the left mouse
button and drag the cursors to a new location. Release the mouse button to drop
the cursors.
The cursors can also used to fix the Manual Origin Location. See the Origin
Location paragraph below.
