are determined by the rules specified in the Split and Merge Rules dialog box
(page 1669).
You can choose to ignore the rules specified in the
Split and Merge Rules dialog
box
(page 1669) by turning on Ignore Split and Merge Rules.
NOTE This functionality is for geospatial features only. For information about
splitting drawing objects, see
Splitting Polygon Objects (page 968).
Split Prompt Options
When you split a feature, you are prompted during the operation. You can
set defaults for some of these options (page 1929) and specify whether to display
those prompts during the split operation or not.
■ Create New/Create Multi-part: Click Create New to split the feature into
two pieces. To creating more pieces, click Create Multi-part.
■ Generate New Feature ID/Use Existing: Click New to auto-generate a
unique identifier for the new features. Click Existing to assign the ID of
the original feature to all resulting features.
■ Would You Like To Draw Or Select The Line For The Split: Click Draw to
draw a line through the original feature where the split should occur. Click
Select to select an existing line or polygon in the original feature that
indicates the location of the split.
Splitting Features with Polygons
If you use a polygon (or mpolygon) to split a feature, the output is divided
into two groups (inside and outside). The groups are collected into as few
multipart types as possible without creating heterogeneous geometric types.
A multipart feature is created for each distinct geometric type (point, line,
polygon) that was in the input.
In the following example, a polygon was used to split a line. The lines outside
the polygon become a multiline feature.
