Editing a Design Context Definition

Below the action bar containing the actions, the Edit Definition tab displays the structure of the design context in a left-side pane. Checkboxes are available next to each subcomponent displayed in the structure, which can be used in conjunction with the other editing tools in the action bar to define the design context. The structure tree-table has the columns described in the following table:

Column	Description
File Name	Displays the structure of the design context in tree format. Selecting a checkbox includes its row in the definition; clearing a checkbox excludes its row.
Definition Rep	Displays the current include/exclude rule assigned to the object.
Resulting Rep	Displays the representation rule that results from the application of all definition rules.

Sub-tab	Description
Attributes	Displays the attributes of the selected component
Visualization	Displays a representation of the design context, as currently defined. For example, excluding a component in the structure pane removes that component from the visualized image.
Rules	Displays the current rules comprising the definition of the design context

Action	Description
Editing actions set
Include Rep	Include selected rows at the shown representation; that is, one of the following representation types: • Assembly Only • Design Mode • Visualization Mode
Clear Rep	Remove all selected, explicit includes/excludes for the selected representation. The selected rows revert to being included.
Exclude	Exclude the selected rows from the design context.
Design Context actions set
Exit Edit Mode	Exit the editing mode. A Confirmation pop-up asks if you want to save changes before exiting.
Save Definition	Save changes to the design context definition.
Viewing actions set
Views	Select default or predefined view of the structure or select Manage Structure Views to customize your list of views.
Display	Access the following display options: • Expand all levels of structure • Collapse all levels of structure • Select 2-pane display • Select 3-pane display (places attribute and rules information in separate panes) • Refresh the display of the structure
Filter actions set
Current Filter	Open the Current Filter window, displaying the configuration specification details.
Edit Filter	Open the Edit Filter window to enable editing of the Configuration Specification, Spatial Filter, or Attribute Filter applied to the design context structure.
Attribute Rules actions set
Manage Rules	Open the Manage Rules window, allowing you to create and manage attribute rules. For more information, see Managing Attribute Rules.

Action

Description

Zoom all

Zoom in on the complete assembly.

Zoom selected

Zoom in on a selected part.

Set spin center

Allows you to assign a spin center to the assembly.

Toggle the automatic selection preference

Allows you to toggle the automatic selection preference to do one or both of the following:

• Automatically Select from Structure to Visualization

• Automatically Select from Visualization to Structure

When both options are selected, clicking on a structure member highlights the member in the visualization and clicking on a member in the visualization pane highlights its row in the structure, expanding the structure if necessary.

Spatial filter

Opens a menu to set or update box, sphere, or proximity type of spatial filter where a component is selected. For more information on using spatial filters, seeAbout Spatial Filters.

Use of filters actually trims the structure tree (removes components). Use of rules can exclude components from membership in the design context, but the excluded components remain in the structure tree (in an unselected state).

Spatial rule

Opens a menu allowing you to set or update box, sphere, or proximity type of spatial rule when a component is selected. For more information about using spatial rules, see Setting a Box Spatial Rule , Setting a Sphere Spatial Rule, Setting a Proximity Rule, and Updating a Spatial Rule.

• Deselecting the checkbox for a member of the structure, excludes that object from the design context. The exclusion is listed on the Rules tab described by listing the parent-child relationships down to the particular object. Subsequent modifications to the design context definition automatically update the rules. For example if a component has been excluded, an “Exclude” rule is created. Upon subsequent re-inclusion the Type field displays “Graphic,” indicating the re-inclusion of the object.
