Model Browser User's Guide

Project Level: Startup View

On startup there is a single node, the project (named Untitled), in the model tree. This node is automatically selected.

When the project node in the model tree is selected at any time, the following functionality is available. This state is called project level. When you start you are automatically at project level, as there are not yet any other nodes to select.

Note    The node selected in the model tree determines what appears in the menus and panes of the rest of the Model Browser.

All Models Pane

(Labeled 1). This pane contains a hierarchical structure showing all the models created within the current project. See Model Tree for a detailed description of the information contained in this pane.

Data Sets Pane

(Labeled 2). All data sets loaded in the current project are displayed in the Data Sets pane (whether in use for modeling or not).

You can select a data set (by clicking it) and then

• Delete it by pressing the Delete key.
• Rename it, by clicking again or pressing F2 (as when selecting to rename in Windows Explorer), then editing the name.
• Open it by double-clicking. Double-clicking a data set opens the Data Editor.

Note    All data sets loaded are visible at the project node and appear in the Data Sets pane. However, they are not necessarily used by any test plan child nodes of that project until you select them within a particular test plan. For example, with a data set loaded at the project node, when you switch to a new test plan node, the Data Sets pane at top right displays 'No Data is selected' until you use the Data Wizard to attach data to that test plan.

The same data set can be used by many test plans within a project, although each individual test plan can only ever use one data set.

Notes Pane

(Labeled 3). The Notes pane contains a list box showing all previous notes on the current project. You use notes to record changes within a project, perhaps by different users, over time.

• You add new notes by clicking the Add new note button in the toolbar, or by pressing the Insert key after selecting the Notes pane by clicking. Notes automatically have the user login name and the date.
• You edit notes (only the user that created them can edit them; user names must match) by select-clicking or by pressing F2 when selected (as when selecting to rename in Windows Explorer). Edited notes have updated time and date fields.
• You remove notes by selecting them and pressing Delete (but only the same user that created them can delete them).
• Notes are automatically added to the project when it is modified (for example, the initial "Created by <username>" note). These notes (listed as user "info") cannot be deleted or edited.

Test Plans List Pane

(Labeled 4). You generate new test plans from the Test Plans list pane by clicking the New button. See Test Plans.

This pane is the Test Plans list pane at startup but changes depending on the level in the model tree that is selected. The list box always displays all the child nodes of whichever node is currently selected in the tree in the All Models pane, and always contains three buttons: New, Delete, and Select.

• The Test Plans list becomes the Response Models list, the Local Models list, the Response Features list, and the Models list as you select the nodes at subsequent levels of the model tree. In each case this pane displays the immediate child nodes of the current node selected. You can use the buttons to delete selected nodes or create new nodes.
• The feature added by clicking New always corresponds to the list items. For example, clicking New when the pane shows a list of test plans adds a new test plan. Clicking New when the pane shows a list of response features opens the New Response Feature dialog, as shown in the following example. The response features you can add are model-specific. This example shows the response features available for a polyspline model.

  

For example, if you choose f(x + datum) and enter 10 in the Value edit box, the new response feature tracks the datum +10. For a torque/spark polyspline model, the datum is MBT (maximum brake torque); so the new response feature is MBT + 10 degrees of spark angle. This allows you to create response features that have engineering interest.

The response features available depend on the model type. For more details on which response features are available, see Local Models and Associated Response Features.

• You can use the Select button to select the best child node, but only when the child nodes are local models, response features, or submodels of response features. In each case clicking the Select button takes you to a selection window where you can compare the child nodes. See Selecting Models.

Tip of the Day

(Labeled 5). Hints about using the Model Browser appear here. You can scroll through more tips using the buttons at the bottom, and you can snap this pane closed or open by clicking the "snapper point" where the cursor changes if you roll the mouse over it.
