Planarizing line features

With the Production Planarize tool, you can create multiple line features by splitting the features at the places where they intersect. This can be useful when you have nontopological line work that has been "spaghetti" digitized or imported from a computer-aided design (CAD) drawing. In addition, Production Planarize notifies the edit environment of features that have been modified or created, which, in turn, runs any automated edit processes such as the global feature identifier (GFID) generator.

When using the Production Planarize tool, you first start an edit session, select a feature to edit, then enter a cluster tolerance for the feature. The cluster tolerance is the distance range in which all vertices and boundaries in a feature dataset are considered identical or coincident. The Production Planarize cluster tolerance is expressed in units of your data.

步骤:
  1. Start ArcMap.
    提示提示:

    If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.

  2. If necessary, load data in the map.
  3. On the main menu, click Customize > Toolbars > Production Editing.
  4. On the main menu, click Customize > Toolbars > Production Editing Advanced.
  5. Click the Production Start Editing button Production Start Editing on the Production Editing toolbar.
    注意注意:

    The Manage Features and Create Attributes, Update Attributes, or Metadata Attributes windows automatically appear when you start an edit session using the Production Start Editing tool.

    提示提示:

    If the Create Attributes, Update Attributes, or Metadata Attributes window does not appear when you start an edit session, click the Link Feature Manager To Attributes Window button Show/Hide Attributes on the Manage Features window.

  6. Select the feature to planarize.
  7. Click the Production Planarize button Production Planarize on the Production Editing Advanced toolbar.

    The Planarize Lines dialog box appears.
