Bug: ArcMap Buffer Wizard does not buffer all the features

Description

Sometimes the ArcMap Buffer Wizard will not create output for all of the features being buffered.

Cause

There are a few possibilities that may be inhibiting the creation of buffers:

A. The features being buffered are in a single data frame and are spread out across the entire world. There is a known limit buffering features at this scale.

B. The geometric complexity of the buffers being constructed are such that non-simple shapes are the result.

C. The features being buffered are multipart polygons or multipart features using attribute values as buffer distances.

Workaround

A. To buffer at a world scale.

1. Select a subset of the features.
2. Buffer the subset; save as a feature class.
3. Switch the selection.
4. Buffer the rest of the features; save as a feature classes.
5. Using the GeoProcessing Wizard, Merge the two buffer results into a new shapefile.

B. If not buffering at a world scale, enforce a simplification procedure during the buffering process.

1. Start the ArcMap Advanced Settings utility.

2. Check the Force geometric simplification during buffer processing checkbox.
3. Click Apply.

Note:
Forcing Simplification will slow down the buffering process.

C. If you are buffering multipart features you may need to create a new feature layer in which all the polygons are single features.
