When you process enterprise industry model point and line features, keep in mind the difference between a vertex and a point.
- A vertex is a component of a line feature whose coordinates are stored with the line feature.
- A point is an enterprise industry model feature, independent from lines. Every line has a vertex at its start point, but point features do not necessarily have one.
The following functions consider the relation between line and point features. Use them to improve the consistency of network geometry, to create correct topological relations, or to adjust inaccuracies due to measurement.
You can insert an existing point into a line feature and optionally split the existing line into two line features.
You can extract an existing point from a line feature and connect the two existing lines into one.
These functions are controlled only by the status line.

|
|
Use Insert Point to move an existing point that lies within a tolerance exactly on the line feature. |
|
|
Use Extract Point to remove a point from a line and delete it from the database. You can remove the point only if it lies on a straight line within a split tolerance. |
Points can be inserted or extracted only if they lie within the split tolerance.
