Editing network object geometry

1. Click the node, customer point, or spatial data item you want to move.

   It turns red to indicate it is selected.

2. [TBC] Move the mouse pointer to the point where you want to drop the node, customer point, or spatial data item, then click again.
2. [TBC] Drag the node, customer point, or spatial data item to its new position.

To move a link, you must move the nodes at one or both ends. However, you can move the internal bends in a link.

Links in the model can have bends on the GeoPlan window so they can more closely follow their actual physical position when building a geographically accurate model.

If your link uses the default (#D) flag for its length field, the bends are taken into account when calculating the length from the GeoPlan coordinates. Otherwise, bends are purely for modelling convenience, and have no effect on computation.

1. Click the link you want to edit.

   Intermediate points are shown as red squares.

2. To add an intermediate point press Ctrl  and click.
3. To remove an intermediate point press Alt  and click.
4. To move an intermediate point click and drag with the mouse button held down.

A polygon or polyline is made up of a series of vertices and edges. To edit an object it must be highlighted using the appropriate tool. This highlights the vertices (the points that can be changed) in red.

See the Polygon and Polyline Objects topic for a list of appropriate editing tools for each type of polygon and polyline.

Individual object types may have specific editing issues. Refer to the help for these objects for more information.

When the object has been edited, click another polygon or polyline for editing, or click the toolbar button (pressing the Esc key has the same effect) to return to the default selection mode.

A vertex can be moved by dragging it to a new location. If two or more vertices are snapped together, the behaviour varies depending on whether snapping mode is switched on: 

• with snapping mode on, all snapped vertices are moved together
• with snapping mode off, all vertices are treated as being independent; only the vertex from the currently highlighted polyline or polygon will be moved.

To move a vertex of a polygon or polyline object:

1. Click the object.
2. Move the cursor over the vertex to be moved. A cross will appear over the vertex when the cursor is locked on that point .

   

3. To reshape the polygon or polyline, hold down the left mouse button and move the mouse to drag the vertex to a new position.

To add a vertex to a polygon or polyline object:

1. Click the object.
2. Move the cursor over the edge of the polygon or polyline to which a new vertex is to be added.
3. To add a new vertex, hold down the Ctrl  key and click the left mouse button.

Vertices can be deleted from polygon or polyline objects. However, polygons must have a minimum of three vertices. Also the two end points of a polyline cannot be deleted. 

To delete a vertex from a polygon or polyline object:

1. Click the object.
2. Move the cursor over the vertex to be deleted. A cross will appear over the vertex when the cursor is locked on that point.

   

3. Hold down the Alt key and click the left mouse button to delete the vertex.

Vertices from different polygon and polyline objects can be snapped together. Once the two objects are snapped together, the shared vertices can be moved as if they are a single vertex as long as snapping mode is switched on. 

To snap two points together:

1. Ensure that snapping mode is switched on.
2. Click the object whose vertex you want to move.
3. Move the cursor over the vertex to be moved. A cross will appear over the vertex when the cursor is locked on that point.

   

4. Hold down the left mouse button and move the mouse to drag the vertex. When close enough to another vertex to snap the points together, a cross is drawn on the vertex you are moving towards.
5. Release the mouse button to snap the two points together.

To unsnap vertices, switch off snapping mode.

With snapping mode off, all vertices are treated as being independent, even if they share the same location. When moving or deleting a vertex, only the vertex in the polygon or polyline currently highlighted will be edited.

You can change the shape of any polygon from the GeoPlan window:

1. Click inside an existing polygon. The polygon borders are shown in blue and the corner points are displayed in red.
2. Drag any of the corner points to new positions to reshape the polygon. When you start dragging, the cursor may disappear. The moving edges of the polygon are shown in red.
3. To add a new corner point to the polygon border, hold down the Ctrl  key and click the border. You can then move this new corner as described above.
4. When you have finished reshaping the polygon, click another polygon or click the toolbar icon to return to the default selection mode.

You can change the position of any selection of network objects. When you move a node, the positions of any links attached to the node are also updated.

To move a selection of network objects:

1. Select the objects to be moved.
2. Select Selection | Selection operations | Geographically adjust selection.

   The Geographical Adjustment of Selection dialog is displayed.

   You can change the scale for the X or Y co-ordinates or move items relative to their current position.

3. When you have made the changes, click OK.

Note: The only position information held for links is the position of any intermediate points. The position of the link ends is defined by the attached nodes. If you select a link without selecting the nodes at each end, and adjust position using this method, only the intermediate points (if any) will be moved. The position of the nodes will remain unchanged.
