Problem: Polygon features do not appear when printing or exporting a rotated data frame

Description

When you print or export a map in ArcMap with a rotated data frame, some polygon features may not appear on the output.

Cause

This is a known issue with geometrically complex features.

Solution or Workaround

As a work-around, use the steps below to simplify complex features. Make backup copies of all data before running any code samples.

  1. Start ArcMap and load the MXD.
  2. Select Start Editing from the Editor toolbar. Specify workspace if prompted.
  3. Use the Select Features tool to select all features in the polygon layer.
  4. Open the Visual Basic Editor.

    In ArcMap, select Tools > Macros > Visual Basic Editor.

  5. In the Project Explorer window, expand Project.mxt and select ArcMap Objects > ThisDocument, then right-click and select View Code.
    [O-Image] Visual Basic Project  Explorer

    Note:
    Code in the Project's ThisDocument code module will only run in the current map document. If you want to store the code in all your map documents, open the Normal.mxt ThisDocument code module instead.

  6. Copy the following code into the code module.

    Code:
    Option Explicit

    '********************************************************************
    'This sub simplifies all of the selected features in a
    'given feature class. An editing session must be started before use.
    '********************************************************************

    Public Sub SimplifyFeature()
    Dim pID As New UID, pEditor As IEditor
    Dim pApp As IApplication, pTopoOp2 As ITopologicalOperator2
    Dim pEnumFeat As IEnumFeature, pFeature As IFeature
    Dim pGeometry As IGeometry
    pID = "esriCore.editor"
    Set pApp = Application
    Set pEditor = pApp.FindExtensionByCLSID(pID)
    If Not pEditor.SelectionCount > 0 Then
    MsgBox "Select one polygon"
    Exit Sub
    End If
    If pEditor.EditState = esriStateNotEditing Then
    MsgBox "Please start editing"
    Exit Sub
    End If
    pEditor.StartOperation
    Set pEnumFeat = pEditor.EditSelection
    Set pFeature = pEnumFeat.Next
    While Not pFeature Is Nothing
    If pFeature.Shape.GeometryType = esriGeometryPolygon Then
    Set pTopoOp2 = pFeature.ShapeCopy
    pTopoOp2.IsKnownSimple = False 'SET KNOWSIMPLE to False
    pTopoOp2.Simplify 'SIMPLIFY
    Set pFeature.Shape = pTopoOp2
    pFeature.Store
    End If
    Set pFeature = pEnumFeat.Next
    Wend
    pEditor.StopOperation "Simplify Features"
    End Sub

  7. Close the Visual Basic Editor.
  8. Run the code.

    A. Click Tools > Macros > Macros to display the Macros dialog box.
    B. Select a macro and click Run.


    All polygons will now appear on the output.
