Selecting feature representations

This topic applies to ArcEditor and ArcInfo only.

Before you can modify feature representations, you must first select them. To select them, the layers they are in must be selectable. Layers drawn with representations are made selectable in the same way as other map layers, using the List by Selection view of the Table of Contents window.

Feature representations are selected using the representation selection tools found on the Representation toolbar. You can select more than one feature representation at a time, or you can select segments of feature representations. Feature representations do not need to be part of the same feature class representation to be selected together.

To select feature representations, you can click the representation symbology itself or the underlying spatial geometry. Generally, these will be coincident. However, some geometric effects will introduce displacements or voids in the representation relative to the geometry.

For example, a representation rule that contains the offset curve geometric effect displaces the symbol away from the underlying geometry. You can click either the symbology or the geometry to select it. The pointer displays a small square when it is over either selectable component.

Selecting whole feature representations

To work with a feature representation as a whole, select it with the Select tool Select Tool or the Lasso Select tool Lasso Select Tool on the Representation toolbar. Selecting whole feature representations will let you view the properties of the representation rule that they follow, alter their geometry, and create overrides by changing their representation rule properties.

The geometry and vertices of selected feature representations will be highlighted in the selection color with a thin line and small solid squares. A rectangular bounding box will surround the full extent of all the selected feature representations.

The geometry will be highlighted after select

Since feature representations are based on features, it is possible to select and manipulate the geometry of whole feature representations using the Edit tool Edit Tool on the Editor toolbar, but you will not have access to all representation functionality. It is recommended that you interact with feature representations using the tools on the Representation toolbar instead.

How to select whole feature representations

  1. In an edit session, click the Select tool Select Tool on the Representation toolbar.
  2. Move the mouse pointer over a feature representation. A small square appears next to the pointer when you are over the symbology or the geometry of a selectable feature representation: Select tool with square.
  3. Click to select a single feature representation or click and drag to select all the feature representations at least partially within the box.

TipTip:

  • Click and drag with the Lasso Select tool Lasso Select Tool to select an irregular arrangement of feature representations. The shape you draw does not have to be completely closed. All feature representations at least partially within the shape will be selected and surrounded by a bounding box.
  • Add feature representations to the selection set by holding the SHIFT key and selecting again with the Select tool Select Tool or the Lasso Select tool Lasso Select Tool.
  • Remove feature representations from the selection set by holding theSHIFT key and clicking selected features with the Select tool Select Tool or the Lasso Select tool Lasso Select Tool.
  • Press the G key to activate the Select tool Select Tool. Press the G key again to activate the Direct Select tool Direct Select Tool. Pressing the G key subsequently toggles between the two tools.

Selecting portions of feature representations

To access the segments and vertices of a feature representation, use the Direct Select tool Direct Select Tool or the Lasso Direct Select tool Lasso Direct Select Tool on the Representation toolbar. Interacting with the segments and vertices of feature representations lets you reshape specific portions only, leaving the rest of the feature representation unaffected. Using these tools, you can select portions of more than one feature representation at a time. This makes it easy to reposition a complete road intersection in one step, for example.

The geometry of feature representations that are at least partially selected will be highlighted in the selection color, but there will be no bounding box. Selected vertices will be solid; unselected vertices will be hollow. Bézier vertices will show their handles when they are selected.

How to select portions of feature representations

  1. In an edit session, click the Direct Select tool Direct Select Tool on the Representation toolbar.
  2. Move the mouse pointer over a feature representation. A small open square appears next to the pointer when you are over the symbology or geometry of a selectable feature representation: Direct select tool with square.
  3. Click to select a single feature representation or drag over the geometry to select the segments and vertices that are at least partially within the box. The geometry is highlighted and all vertices within the selection box are selected.

TipTip:

  • Click and drag with the Lasso Direct Select tool Lasso Direct Select Tool to select an irregular arrangement of segments and vertices from one or more feature representations. The shape you draw does not have to be completely closed. All segments and vertices at least partially within the shape will be selected. All vertices within the shape will be selected and appear solid.
  • Using the Direct Select tool Direct Select Tool, click and drag over one or more vertices of a selected feature representation to change the selected set of vertices, or press and hold the SHIFT key to add to the selected set of vertices.
  • Add feature representations to the selection set by pressing and holding the SHIFT key and selecting again with the Direct Select tool Direct Select Tool or the Lasso Direct Select tool Lasso Direct Select Tool.
  • Unselect one feature representation from the selection set by right-clicking it with the Direct Select tool Direct Select Tool and choosing Unselect Representation from the menu.
  • Select all the segments and vertices of a feature representation by right-clicking it with the Direct Select tool Direct Select Tool and choosing Select Part from the menu.
  • Unselect segments and vertices by right-clicking a selected feature representation with the Direct Select tool Direct Select Tool and choosing Unselect Part from the shortcut menu.
  • Select a subset of vertices from a single selected feature by pressing and holding the CTRL key while using the Direct Select tool Direct Select Tool or the Lasso Direct Select tool Lasso Direct Select Tool.
  • Select an inverse subset of vertices from a single selected feature by pressing and holding the CTRL and SHIFT keys together while using the Direct Select tool Direct Select Tool or the Lasso Direct Select tool Lasso Direct Select Tool.
  • Press the L key to activate the Lasso Select tool Lasso Select Tool. Press the L key again to activate the Lasso Direct Select tool Lasso Direct Select Tool. Pressing the L key subsequently toggles between the two tools.
