Adding Semantic References to Annotation Elements

To ensure inspection tools automatically associate annotations to the appropriate faces to which they refer, an additional reference may be needed.

  • For dimensions, gtols, datum reference features, and datum targets: Add the additional references

  • For notes, surface finishes, symbols, and legacy set datums and datum targets: Add the annotation element to an annotation feature.

  • Redefine the annotation feature.

  • Select the associated annotation element.

  • Select the additional references to associate.

Adding Semantic References to Annotation Elements

Inspection tools need to have a relationship between the annotations and the surfaces to which they refer. This relationship may be defined if you use surfaces to define the annotation. However, sometimes you may use edges, centers, or other features to create an annotation. Thus, the relationship between the annotation and the correct surface references needs to be added.

Adding Semantic References to Dimensions, Geometric Tolerances, Datum Feature Symbols, and Datum Targets

Figure

Figure 1 - Adding a Semantic Reference

To add semantic references to dimensions (both driven and driving), geometric tolerances, datum feature symbols, and datum targets, simply select the annotation element you need to add additional semantic references to. In the ribbon tab for the selected annotation element, click the References icon in the References group. You can then press CTRL and add any additional surface references. You can then select the annotation element, and the associated references highlight in the graphics window.

Adding Semantic References to Notes, Surface Finishes, Symbols, and Legacy Set Datums and Datum Targets

Figure 2 - Adding a Note to an Annotation Element

To add semantic references to notes, surface finishes, symbols, and legacy set datums and datum targets, perform the following:

  • If one does not already exist, create an annotation feature for the combination state containing the annotation element you need to add the semantic references to.

  • Redefine the annotation feature and assign the annotation element you need to add the semantic references to.

  • Select the annotation element in the Annotation Feature dialog box.

  • Select the additional surface references in the graphics window.

In the model tree footer, you can expand the annotation feature and select the dimension. The associated references highlight in the graphics window.

The only way you can add semantic references to notes, surface finishes, symbols, and legacy set datums and datum targets is to add them to an annotation feature first.

Steps

  • Task 1. Associate an additional reference surface to a driven dimension annotation element. Disable all Datum Display types.

  • In the ribbon, select the Annotate tab. Select the 7A combined state tab.

Figure

  • In the detail tree, select driven dimension ad53 .

  • In the ribbon, click References Figure . Only one of the two reference cut surfaces are associated with the dimension. The second wall surface must be added as an additional reference.

  • Press CTRL and select the coplanar surface to add it. Click OK .

Figure

  • Click in the background to de-select the dimension.

  • Task 2. Associate an additional reference surface to a driving dimension annotation element. In the detail tree, select driving dimension DRV_DIM_D15 . Figure The top two surfaces are already associated with this dimension because they are part of the same sketch feature.

  • In the ribbon, click References Figure .

  • Press CTRL and query-select the bottom surface. Click OK .

Figure

  • Task 3. Associate an additional reference surface to a note annotation element. Select the 7D combined state tab.

  • In the model tree, scroll to the bottom and expand the Footer node.

  • Select annotation feature 7D and click Edit Definition Figure from the mini toolbar.

  • In the Annotation Feature dialog box, click Consume Existing Element Figure .

  • In the detail tree, select Note_46 . Click OK .

Figure

  • Press CTRL and query select the intent surface for each of the two holes. Figure

  • Click OK from the Annotation Feature dialog box. Click in the background to de-select all geometry.
