A secondary dimension template that specifies additional points to include in the dimension chain. Many delivered dimension templates have existing anchor templates. These anchor templates are delivered in the [Reference Data Folder]\SharedContent\Drawings\Catalog\Dimensions\Templates\ folder.

You can attach multiple anchor templates to the main template, or change the anchor rule that the main template uses. To add an anchor template to the main template, or to change an existing anchor template, perform the following steps:

  1. Open the main template's rule in the Dimension Rule Manager.

    Any existing anchor templates display in the Anchor text boxes. An empty Anchor text box displays below the last populated Anchor text box.

  2. To add another anchor template to the main template, type the name of a valid anchor template in the empty Anchor text box,

    -OR-

    1. Click the browse button (browse_rulemanager_BUTTON) in the empty Anchor text box to access the Select a dimension anchor window;

    2. Select a dimension anchor, and then click Open to return to the Dimension Rule Manager.

    The anchor template you added displays below the existing anchor template, and another empty Anchor text box displays below the anchor template you just added.

  • Delete the anchor template name in the Anchor text box to remove that anchor from the main template.

  • The software places both internal and external dimensions for objects (such as pipes or equipment) and anchored objects (typically grid lines) when you use the Default annotation control generator. For more information, see Default (DrawingDimGenerator).

The following examples show how you can include anchor objects that are not the subject of a dimension chain when you place dimensions.

In the first example, a dimension is placed between two pumps. The columns are not included in the dimension chain.

anchor_dimensionAnchor value not defined

1 - Pump
2 - Column
3 - Dimension

The following example shows the anchor dimensions between the columns and the pumps.

anchor_dimensionAnchor value defined

1 - Pump
2 - Column
3 - Overall dimension
4 - Dimensions

  • The overall dimension in the previous example is shown for reference.

  • The following geometric analyzer modules use the Anchor property.

    • Margin (DrawingGAMarginOnly)

    • Margin with Occluded Graphics (DrawingGAMarginOnlyWithOccludedGraphics)

    • Pipe Segments (DrawingGAPipeSegments)

    • Default (DrawingGeometricAnalyzer)
