Introduction

1 - 1 Welcome Screen

When you start Tecplot 360 EX, the Welcome Screen, shown below, appears. You can also open it at any

time (even while working on a plot in Tecplot 360 EX) by choosing View>Welcome Screen.

The Welcome Screen contains links that help you quickly get started working with your data and Tecplot

360 EX.

• Across the top are links for creating a new layout and for opening existing layouts and data

files.

• The left section provides a list of layouts you have recently worked with.

• The right column contains links to documentation and other resources to help you get the

most out of Tecplot 360 EX.

• At the very bottom of the right column is information for contacting Technical Support,

including the version and platform information you will need for a support incident.

The Welcome Screen automatically disappears when you open a layout or create a new one. You may also

close it manually by clicking the red X button in the upper right corner; this returns you to your existing

layout if you have chosen View>Welcome Screen while you were working with a plot.

1 - 2 Input Devices

Tecplot 360 EX supports the following input devices:

• Standard mouse - Used for pointing at, selecting, and manipulating objects in the workspace;

changing the view; choosing fields and manipulating controls in dialogs and sidebars; and

performing actions or commands using the toolbar or menus. Most mice have multiple buttons

and a scroll wheel, which provide quick access to specific functions.

Input Devices

• Keyboard - Used for entering data and text and for activating commands using menu

shortcuts. In conjunction with a mouse, can be used to switch modes when clicking or

dragging.

• 3D mouse - A secondary input device that allows 3D Cartesian plots to be zoomed, translated,

and rotated with a touch. Additionally, the always-active 3D mouse doesn’t make you select

mouse modes, commands, or keyboard shortcuts. A 3D mouse can therefore enable faster

exploration of your data and improve the experience of working with your 3D plots.

Actions available with a 3D mouse include:

• Translation - Push the mouse cap left or right, pull it up, or push it down, to translate

the plot left/right or up/down on the screen.

• Zooming - Push the mouse cap toward you or away from you to zoom the plot. Hold

down the Alt key while zooming to switch zoom methods.

The default zoom method depends on whether the current frame’s 3D view mode is

perspective or orthographic (see Section 7 - 4.6 “Three-dimensional View Details”

page 184). The results of zooming using the 3D mouse and the Alt key are shown here.

• Rotation - Rotation is around the defined center of rotation, by default the center of the

data. However, the axis of rotation is relative to the screen rather than to the data.

•X axis - Tilt the mouse cap forward or back to rotate around the screen’s X axis, as

if rolling your plot toward you or away from you.

•Y axis - Twist the mouse cap clockwise or counterclockwise to rotate around the

screen’s Y axis, as if on a lazy susan.

•Z axis - Tilt the mouse cap left or right to rotate around the screen’s Z axis, like the

hands of a clock.

With practice, it is possible to perform more than one of these operations at the same time. At

first, though, it is best to be careful to invoke only one function at a time.

Most 3D mice also have one or more buttons, which can be mapped to commands that you use

frequently using the software provided with the device.

Tecplot 360 EX supports the following actions (built-in to the 3D mouse software) that may be

mapped to buttons using the device software:

• Fit (same as View>Fit Surfaces)

• Front, Back, Top, Bottom, Left, and Right View

• Isometric View 1 (Tecplot 360 EX default view) and 2 (theta 180° from default)

Tecplot 360 EX supports 3D mouse products from 3Dconnexion, such as the

SpaceMouse, SpaceNavigator, and SpacePilot lines, and only on the Windows platform.

Pushing or pulling mouse cap In perspective mode In orthographic mode

Normal (without Alt key) Changes view distance Changes view width

Alternate (pressing Alt key) Changes view width Changes view distance

An area of interest can be inspected in greater detail from any angle if the origin of

rotation is assigned to it. Mapping the “o” key (orientation change) to a 3D mouse via

the device GUI may facilitate a more natural workflow. Simply point the regular mouse

cursor at the area of interest and press the orientation change button.

Interface

• Insert - Use the Insert menu to add text and geometries (polylines, squares, rectangles, circles,

and ellipses). If you have a 3D zone, you may also use the Insert menu to insert a slice. If the

plot type is set to 2D or 3D Cartesian, you may insert a streamtrace.

• Animate - Use the Animate menu to create animations of your plot.

• Data - Use the Data menu to create, manipulate, and examine data. Types of data

manipulation available in Tecplot 360 EX include zone creation, interpolation, triangulation,

and creation or alteration of variables.

• Frame - Use the Frame menu to create, edit, and control frames.

• Options - Use the Options menu to control your Tecplot 360 EX experience, including rulers,

grids, and performance.

• Scripting - Use the Scripting menu to play or record macros, and to access the Quick Macros

Panel.

• Tools - Use the Tools menu to launch an add-on.

• Analyze - Use the Analyze menu to examine grid quality, perform integrations, generate

particle paths, extract flow features, and estimate numerical errors.

• Help - Get help for Tecplot 360 EX features, or view the About dialog, which contains version

and platform information.

1 - 3.2 Context Menu and Toolbar

In many places within Tecplot 360 EX, clicking with the right mouse button displays a context menu that

gives you quick access to just the operations most relevant to what you’re clicking. Often, these operations

are also available in some other way, such as using a toolbar button, the pull-down menus, or a dialog.

In the Tecplot 360 EX workspace, the following objects have context menus with the specified functions:

• Frames - Change frame order, load and save frame style, frame details

• Axis - Axis settings

• Slices - Hide, edit slice details, extract slices, slice style

• Iso-surfaces - Hide, choose variable, edit iso-surface details, extract surfaces, change iso-surface

style

• Zones - Hide, deactivate, zone style

• Streamtraces - Extract, delete, streamtrace settings

• 3D orientation axis - Hide axis, axis settings

• Line maps - Deactivate, copy, change curve type, mapping style, Fourier transform (when

applicable), show curve details on plot; write curve details or data to file

• Legends - Hide, change box type, legend settings

• Geometries (shapes) - Change line and fill color, delete, edit geometry settings. For polylines,

you may also extract data along the line.

• Text - Change color, cut, copy, delete, align(left, right, center, top, bottom), text settings.

When working with zones, slices, and iso-surfaces, a context toolbar appears

above the context menu. This toolbar allows you to turn on or off the grid,

contour, vector, shade, edge, and translucency layers for the selected

object(s) by clicking the icons. (Iso-surfaces do not have vector or edge layers.) Additionally, you may

adjust frequently-used style settings for each layer using the drop-down menu to the right of each icon, for

example selecting a color for the grid (or choosing a variable by which to color it).

A different context toolbar appears when you right-click a line in XY or polar line plots.

This toolbar allows you to turn on or off the line, symbol, and error bars for the selected

line map by clicking the icons. You can also adjust the attributes of these (for example,

line color, symbol shape, or error variable) using drop-down menus to the right of each icon.
