About Semantic Query
Semantic Query is a special analyze mode that helps you to obtain the semantic information related to annotations. The Semantic Query button in the Query group of the Annotate tab launches the Semantic Query mode. In this mode, you can query annotations and analyze the complex relationships between the annotations and the geometry in Model-based Definition (MBD) environment.
You can query a semantic relationship of an annotation when annotation contains at least one semantic reference. The reference can be a placement reference or an additional reference. The following references are semantic:
• Surface
• Quilt Surface
• Datum Plane
The Semantic Query Toolbar
The Semantic Query toolbar appears when you launch the Semantic Query mode. You can use the commands on this toolbar to control the visibility of the semantic objects.
The following icons on the Semantic Query toolbar are used to display or hide the related semantic objects:

Description
|
|---|---|
 |
Displays all the annotations describing the highlighted references of the currently selected annotation.
|
 |
Displays the primary references of the selected annotation.
|
 |
Displays the references of annotations associated with the currently selected annotation (secondary references).
|
 |
Displays the datum symbols, such as Datum Feature and Datum Target associated with the currently selected annotation.
|
 |
Displays a Datum Reference Frame (DRF) coordinate system associated with the currently selected GTOL.
|
 |
Displays a GTOL associated with the currently selected datum symbol, such as Datum Feature or Datum Target.

Selecting Geometry
You can click Semantic Query and select an annotation or select the annotation and click Semantic Query.
You can select the annotation in the Graphics window or the Detail Tree.
Clearing the Selection
You can right-click in the Graphics window and select the Clear option to clear the selection of annotations.
Highlighting Objects Related to the Selected Annotations
When you select an object, all the semantic objects, such as model faces, annotations, and supplementary geometry are highlighted in different colors.
You can customize the following colors in the Creo Parametric Options dialog box:
• Primary highlight
• Secondary highlight
• Preselection highlight
• Selected
Combination States
You can right-click in the Graphics window and select the Add to Combination State option to add the currently selected annotation to the current Combination State.
You can right-click in the Graphics window and select the Add highlighted annotations to Combination State option to add all the currently selected and highlighted annotations to the current Combination State.
Weld Symbols
The weld symbols are supported by semantic queries. When weld symbols contain semantic references, its semantic relationship can be queried using semantic query.
