Why is the geometry of a complex feature invalid?
“The feature’s geometry could not be modified, invalid geometry.” This is generally due to the fact that the next vertex in the complex edge feature has a junction connected to it at mid-span. Cause. By default, edge features in the geometric network have a 1:1 ratio between the geometric and logical networks.
How many IDs are in a geometric network?
By default, edge features in the geometric network have a 1:1 ratio between the geometric and logical networks. This means that every edge feature has at least 1 Element ID in the logical network. While this statement always applies to simple edges, it may not always apply to complex edges.
Where can I find the Glencoe geometry solutions manual?

Can a logical element be associated with a zero length geometry?
Logical Network Element IDs cannot be associated with zero-length or empty geometries; this applies to Element IDs associated with an entire network feature or with a subsection of a complex edge. The violation of this rule during the edit is what raises the error message when the edit is finished.
How do I create a feature with null geometry?
Select the row in the table containing null geometry. Make sure to select only one row at a time. Click the Replace Geometry tool. If the feature selected has valid geometry already, a message is received indicating this. Click the map to define the feature’s shape. To create a point, click the map where the feature should be placed.
When is a zero length geometry not valid?
Zero length geometries are not valid in the geometric network whether they apply to the geometry associated with entire network features or to the geometry associated with a section of complex edge that has mid-span connectivity. Error: The geometry for an edge element may not be zero length.
When to use stisvalid on a geometry instance?
This method may cause a change in the type of the geometry instance, as well as cause the points of a geometry instance to shift slightly. The first example creates an invalid LineString instance that overlaps itself and uses STIsValid () to confirm that it is an invalid instance. STIsValid () returns the value of 0 for an invalid instance.
