To split a feature into
two parts, for example a parcel, use the MAPFEATURESPLIT command.
The resulting feature property values are determined by the rules
specified in the Split and Merge Rules dialog box.
You can choose to ignore
the rules specified in Split and Merge Rules dialog box
by turning on .
Split Prompt Options
When you split a feature,
you are prompted during the operation. You can set
defaults for some of these options 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
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.
The line segment inside
the polygon becomes a line feature (shown in blue on the right).
The line segments outside the polygon become a multiline feature
(shown in red).
