Delete a Vertex

Delete a vertex from a line, alignment, polygon, shape (pipe) or terrain model.

• Objects in the same location are picked using the following criteria:
  1. Layer draw order - Objects on layers drawn last are selected first.
  2. Object type - Line, alignment, polygon, terrain model, shape.
  3. Unique identifier - Objects created first are selected first.
• If more than one object is using the vertex, or if vertices are very close, tentatively pick the vertex until the correct line, alignment, polygon, shape or terrain model is picked.
• The vertex is deleted from the specified object only. The vertex is retained by all other objects using the vertex.
• The vertex is deleted from the project when there are no remaining objects using the vertex.
• The vertex is deleted from an alignment, only if it is the first or last vertex in the alignment.
• If deleting a vertex results in less than the minimum vertices required to form the object, then the object is also deleted.
• Vertices can be deleted from straights, arcs, transition curves, splines, polygons, shapes (pipes) and terrain models.
• To delete an object, select the object then press Delete or click
• For alignments with a design standard, you can delete intersection points only. The curves in the alignment will be recomputed. If a curve does not display, a curve could not be computed within the constraints. On the Alignment tab, in the Properties group, click to examine the curves at the intersection points.
