The following tools are contained in the dynamic portion of the Tool Palette when the Map Module is active. Only one tool is active at any given time. The action that takes place when the user clicks in the Graphics Window depends on the current tool. The following table describes the tools in the map tool palette.

Tool	Tool Name	Description
File:Select Feature Point or Node.bmp	Select Feature Point or Node	The Select Feature Point or Node tool is used to select stand alone feature points or the ends of arcs. A single point is selected by left-clicking directly on it. Multiple points can be selected at once by dragging a box. To drag a selection box, left-click and hold the button while dragging the mouse to the appropriate dimensions; release the button to enclose and select the contents. Additional points can be appended to the selection list by holding the SHIFT key while selecting by any method. Selecting new points without holding the SHIFT key will first clear the selection list and then add the newly selected points. A selected point can be removed from the selection list by holding the SHIFT key as it is reselected. Pressing the ESC key will clear the entire selection list. Right-clicking will open a menu specific to this tool. Feature points are locked so they are not accidentally dragged. When a single point is selected, its location is shown in the Edit Window. The coordinates can be changed by typing in the edit field. The Graphics Window’s status bar will display information on the selected items depending on the settings find through the File | Info Options command in the File Menu. Selected points can be deleted by selecting the Edit | Delete menu command on the Edit Menu, by pressing the DELETE or BACKSPACE keys, or from the right-click menu. Arcs attached to the deleted points are deleted. This tool is available when one or more feature points exist.
File:Create Feature Point.bmp	Create Feature Point	The Create Feature Point tool is used to place new feature point in the current coverage. A single point is created at a time by left-clicking at the coordinate desired. The newly created point is selected to allow Z Coordinate changes in the Edit Window. This tool is always available, however, creating a feature point is only allowed while in plan view.
File:Select Feature Vertex.bmp	Select Feature Vertex	The Select Feature Vertex tool is used to select one or more vertices on an arc. These vertices define the shape of the arc. The vertex may have a "z" elevation specified, but no other attributes are associated with the feature vertices.
File:Create Feature Vertex.bmp	Create Feature Vertex	The Create Feature Vertex tool is used to create a new vertex on the interior of an arc. The vertex is created at the current arc location, but can be selected and moved to change the shape of the arc. The vertex may have a "z" elevation specified, but no other attributes are associated with the feature vertices.
File:Select Feature Arc.bmp	Select Feature Arc	The Select Feature Arc tool is used to select one or more existing feature arcs. This is typically done to assign attributes to an arc or delete the arc. A single arc is selected by left-clicking directly on it. Double-clicking on the arc will bring up the arc attributes dialog or that arc. Multiple arc can be selected at once by dragging a box. Additional arcs can be appended to the selection list by holding the SHIFT key while selecting by any method. Selecting new arcs without holding the SHIFT key will first clear the selection list and then add the newly selected points. A selected arc can be removed from the selection list by holding the SHIFT key as it is reselected. Pressing the ESC key will clear the entire selection list. Right-clicking will open a menu specific to this tool. Feature arcs may have elevations associated with the arc as an entity. This is independent of the node and vertex elevations. When a single arc is selected, its elevation is shown in the Edit Window. The coordinates can be changed by typing in the edit field. Multiple feature arcs may also be selected to create a feature arc group to associate attributes with a string of arcs rather than a single arc. These arcs must connect end to end. The arc group is created from the Feature Objects menu command. The Graphics Window’s status bar will display information on the selected items depending on the settings find through the File | Info Options command in the File Menu. Selected arcs can be deleted by selecting the Edit | Delete menu command on the Edit Menu, by pressing the DELETE or BACKSPACE keys, or from the right-click menu. Nodes attached only to the deleted arcs are deleted. This tool is available when one or more feature arcs exist.
File:Create Feature Arc.bmp	Create Feature Arc	The Create Feature Arc tool is used to create a new feature arc.
File:Select Feature Arc Group.bmp	Select Feature Arc Group	The Select Feature Arc Group tool is used to assign attributes to a string of arcs. The group must be created before it can be selected as a group. The attributes of the group then operate just as if the group was a single arc.
File:Select Feature Polygon.bmp	Select Feature Polygon	The Select Feature Polygon tool is used to select polygons to assign attributes to them. The attributes associated with the polygon depends on the coverage type. Double-clicking on the polygon will invoke the polygon attributes dialog for the polygon. Multiple polygons may be selected just as with arcs and nodes. The polygons must be created using the Feature Objects menu command.
File:Create 1D Grid Frame.jpg	Create 1D Grid Frame	The Create 1D Grid Frame tool only appears when the coverage is associated with a 1D grid model (GenCade). This tool is used to create a guide for the 1D grid that will be generated for a coastal morphology analysis.
File:Select 1D Grid Frame.jpg	Select 1D Grid Frame	The Select 1D Grid Frame tool only appears when the coverage is associated with a 1D grid model (GenCade). This tool is used to select/edit the grid frame that is used to generate the 1D grid.
File:Create 2D Grid Frame.bmp	Create 2D Grid Frame	The Create 2D Grid Frame tool is used to create a new grid frame for the creation of Cartesiona grids. This tool is only available for coverages related to Cartesian grid models. The grid frame is defined by clicking three times in the graphics window. The first click defines the origin. The second click defines the I axis of the grid frame (both extents and direction). The third click defines the extents of the J axis. The direction is set to be perpendicular to the I axis.
File:Select 2D Grid Frame.bmp	Select 2D Grid Frame	The Select 2D Grid Frame tool allows the user to select a grid frame and alter its position, orientation and size. This tool is only available for coverages related to Cartesian grid models.

General Tool Right-Click Menus

The following is a list of options that appear in every tool's right-click menu:

• Clear Selection – The Clear Selection command undoes the selection of the object that was clicked on.
• Invert Selection – The Invert Selection command selects every object of the same type selected, and undoes the selection of the object that was originally selected.
• Zoom to Selection – The Zoom to Selection command zooms to a closer view of the object selected.

Tool Specific Right-Click Menus

Each tool in the Map module has its own right-click menu. When the object is selected, one can right-click and a menu will appear. The following is a table showing all of the different tools of the map module with their respective right-click menus.

Tool	Tool Name	Right-Click Menu
File:SelectMeshNodestring.bmp	Select Feature Point or Node	Convert to Vertex/Vertices – Converts node(s) to Vertex/Vertices Delete – Deletes node(s) Transform – Moves the node(s) either by scaling, translation, or rotation. User specified.
File:Select Feature Vertex icon.bmp	Select Feature Vertex	Convert to Node(s) – Converts Vertex/Vertices to node(s). Delete – Deletes vertex/Vertices Transform – Moves the vertex/vertices either by scaling, translation, or rotation. User specified.
File:Select Feature Arc icon.bmp	Select Feature Arc	Create Arc Group – Creates a group out of two or more arcs selected together. Delete – Deletes arc(s) selected. Split Arc(s) – Sub divides arc(s) at the vertices. Offset Arc(s) – Invokes the offset arc dialog which prompts the user for offset distances and options to create one or more arcs offset from the selected arc(s). Align Arc(s) with Contour – Prompts the user for a scattered dataset and dataset value. SMS then attempts to move the nodes and vertices of the selected arc(s) to the closest points on a contour at that value. This is done by processing each location individually. For each point, SMS extracts the contour value from the TIN/dataset and the gradient of the TIN at the (x,y) location. It then tracks up or down gradient to intersect with the contour at the specified dataset value. If a local extrema is encountered before finding the contour, the operation fails. Redistribute Vertices – User specified distribution of vertices. Vertices can be evenly distributed based on spacing or number of vertices desired. Reverse Arc Direction – Reverses direction of arc. The arc direction only impacts the direction of extracted 2D plots and the direction for defining a domain. Smooth Arc(s) – Repositions each vertex on an arc to smooths the arc(s). The user specifies a self weight and number of neighbors (n) on either side to use in the smoothing process. The first vertex is smoothed using only the first node and second vertex as neighboring points. Similarly, the last vertex is smoothed using the second to last vertex and terminal node of the arc as neighboring points. In other words, there must be an even number of neighbors on either side of the vertex being smoothed. The new position of each vertex is the original position multiplied by the specified self weight summed with the average location of all the neighbors being considered multiplied by (1.0 - specified self weight). Transform – Moves the arc either by scaling, translation, or rotation. User specified. Attributes – Type specific. Many types do not have any attributes in their arcs. Select Connected Arcs Turning Left – Selects the arc to the left of the originally selected arc.
File:Select Feature Arc Group icon.bmp	Select Feature Arc Group	Delete – Deletes Feature Arc Group(s).
File:Select Feature Polygon icon.bmp	Select Feature Polygon	Delete – Deletes Feature Polygon (not the arcs that make up the polygon). Attributes – Model specific.
File:Select 1D Grid Frame icon.jpg	Select 1D Grid Frame	Properties– Invokes the "Grid Frame Properties dialog that allows the user to specify the location, orientation, size and spacing of the grid frame using text fields; Specific to 1D grid coverages.
File:Select 2D Grid Frame icon.bmp	Select 2D Grid Frame	Type Specific Properties – Shows the properties of the 2D grid frame. Model specific.
