After drawing the stream alignment in the map window, there are many options available for adjusting the stream alignment. You can refine and re-shape the stream alignment by adding, moving, and deleting vertex points from stream elements. Adjacent vertex points are connected by straight lines. Thus, when you delete a vertex point, the alignment will adjust so that the two vertex points that had surrounded the deleted vertex point are connected by a straight line. The alignment will adjust similarly when you move vertex points.

Add Vertices to a Stream Element

To add vertex points to an existing stream element: 

  1. Using the stream alignment tool, double-click the stream element that you want to add a vertex point to. The stream element will turn red, and vertex points will be displayed in blue.
  2. Place the pointer where you want to add a vertex point. Hold down the CTRL key, and click. The new vertex will appear on the stream alignment.
  3. Repeat the process until all new vertices have been added. Double-click in an open area of the map to finalize the edits of the stream alignment (the alignment will de-select).

Move the Vertices of a Stream Element

To move vertex points on an existing stream element: 

  1. Using the stream alignment tool, double-click the stream element that you want to add a vertex point to. The stream element will turn red, and vertex points will be displayed in blue.
  2. Hover your mouse over the vertex point you wish to move until the cursor turns into a plus sign. Click on the vertex to select it, then drag it to the new location and release the mouse to complete the edit.

  3. Repeat the process until all necessary vertices have been moved. Double-click in an open area of the map to finalize the edits of the stream alignment (the alignment will de-select).

Delete Vertices from a Stream Element

To delete vertex points from an existing stream element: 

  1. Using the stream alignment tool, double-click the stream element that you want to add a vertex point to. The stream element will turn red, and vertex points will be displayed in blue.
  2. Hold down the Shift + CTRL keys and click on the vertex point you want to delete. The vertex point will disappear from the stream element.
  3. Repeat the process until all necessary vertices have been deleted. Double-click in an open area of the map to finalize the edits of the stream alignment (the alignment will de-select).
