I want to split a line haveing zigzag(different angles) but bthere are many vertics. I have an option in Arc GIS 10 to split from vertics but i need to split only where the angle or dimension is changed
Here are a few steps that might help accomplish your task-
"Simplify Line" or "Smooth line" - to remove in-line vertices.
"Feature Vertices To Points" - covert vertices to Point features.
optional - snap points to the original line if they moved during Simplify line. (Arc 10.0, editing tools, snap)
"Split Line at Point" - break the original line.
