WMS:Edit Menu

The Edit menu is one of the standard menus and is available in all of the modules. The commands in the Edit menu are used to select objects, delete objects, and set basic object and material attributes.

The Edit menu contains the following commands:

Delete

The Delete command is used to delete any selected objects. This command is also equivalent to hitting the DELETE or BACKSPACE keys. A macro for the Delete command File:Delete icon.bmp is found in the Macro tool palette.

Confirm Deletions

Whenever a set of selected objects is about to be deleted, the user is prompted to confirm the deletion. This is meant to ensure that objects are not deleted accidentally. Selecting the Confirm Deletions item from the General tab of the Preferences dialog (accessed by the Preferences command of the Edit menu) can turn this option off. The check mark in front of the command is present when this option is turned off and is not when it is turned off.

Delete All

The Delete All command is used to delete all of the data associated with the active module, whether or not there are selections. It is similar to the New command in the File menu except that the New command deletes all data in all modules.

Select All

The Select All command (Ctrl+A) selects all items associated with the current selection tool, providing that the tool supports the Select All option.

Select With Polygon

The Select With Polygon command allows the user to enter an irregular polygon enclosing the items to be selected (one of the selection tools must be active). To enter the polygon, click on both the polygon's starting point and each intermediate point defining the polygon and double click on the ending point. All items within the polygon will be selected. If an error occurs while entering a polygon, the following keys can be used:

• BACKSPACE or DELETE – Back up one line segment.
• ESC – Abort entering the polygon, and selection by polygon.
• CONTROL – Holding the CONTROL key down while moving the cursor causes all previously entered segments of the polygon to be moved simultaneously.

In addition to defining a polygon using the cursor, a polygon created in the Map module may be chosen to define a selection polygon.

Units

WMS Units dialog

Units are determined by the data that you read into WMS. For example if you read a TIN in which has coordinate vertices in meters then you are responsible to tell WMS that you are working with metric units so that proper conversions are made when computing areas, slopes, and other geometric values.

Units are specified in the Units dialog. Model units are the units of the geometric data (i.e. TIN, DEM, Feature Objects, etc.) you are using to develop hydrologic and hydraulic models whereas parameter units are the units you wish to have areas and distanced converted to when performing calculations.

IMPORTANT: WMS requires that the Horizontal and Vertical units be the same in order to correctly estimate slopes.

Units are closely related to the Current Coordinate System and so access to this dialog is given in order to change the current units setting.

Current Coordinates

See Coordinate Systems for more information.

Coordinate Conversion

Converts data from one coordinate system to another. See Coordinate Conversions for more information.

Single Point Conversion

The Single Point Conversion dialog allows a user to convert a coordinate (xyz point) between to coordinate systems. This dialog can be accessed from two locations within XMS programs:

1. Edit menu, Convert Single Coordinate item
2. Register Image Dialog

The dialog consists of two sides. On the left side, the original (or Convert from) coordinate system is entered. On the right side, the final (or Convert to) coordinate system is entered. The options for the two sides are described on the Coordinate Systems page.

The other items in the dialog include:

• Enter coordinates – Enter the original (or from) coordinates.
• New Coordinates – View the final (or to) coordinates.
• Convert – Perform the conversion.
• Create Mesh Node/Feature Point – Create a mesh node (if in the mesh module) or a feature point (if in the map module) at the final coordinates when OK is pushed.

Materials

Materials Data dialog

When doing 1D Hydraulic modeling in WMS it is useful to define material types. Cross section segments have material ID's associated with them and relate to the Materials defined with this command. These material types often represent different types of bed material or areas of fluid properties. A global list of material attributes is maintained that can be edited using the Materials Data command. The command brings up the Materials Data dialog where each material is assigned an ID number. This dialog can be used to delete unused materials, create new materials, and assign a descriptive name, color, and pattern to a material. This general information is saved in the material file.

The Legend toggle controls the display of a legend of the materials in the Graphics Window. The options for the legend are edited in the Legend Options dialog. These options include:

• The name to be displayed on the legend.
• The font to be used in the legend.
• The specification of which corner of the screen the legend will appear in.
• The size of each entry in the legend.
• Whether all materials or active materials will be included in the legend.

When a new cross section is created, a user specified default material is assigned to the new section.

Material ID's can be assigned to polygons of an Area coverage and used to map to cross section segments when automatically extracting them from TINs.

Model specific material properties such as Manning's n are edited using commands local to the model menu.

Preferences

Opens the Preferences dialog. See Preferences for more information.

Copy to Clipboard

The contents of the Graphics or Hydrograph windows can be saved to the Windows clipboard by selecting the Copy to Clipboard command (Ctrl+C). The clipboard can then be “pasted” into other Windows programs, such as word processors or drawing packages.

Other dialogs and plot windows have separate commands available for copying text results or plots to the clipboard for inclusion in other documents.

WMS Copy To Clipboard dialog

Paste

The Paste command in the Edit menu allows the user to paste tabular data (generally this is xyz data used to create a TIN or scattered dataset) directly into WMS. The tabular data can be copied from a text file or from a spreadsheet and then pasted into WMS.

When this command is executed the File Import Wizard is launched.
