WCADI: Units, Screens, Menus and Functions
WCADI is menu-controlled. The user starts from the Initial Screen, which contains many menus, each with a number of submenus leading to different functions. In this chapter, the overall menu structure and the submenus are described with references to the details about each function.
WCADI can be used graphically or non-graphically. In the non-graphical mode, design parameters are entered by means of filling-in standard tables; in the graphical mode, the input is a combination of graphical entries from the digitizing tablet or screen, but it leads to the completion of part of the same tables.
In both modes the manual input is limited to the minimum, leaving as many calculations as possible to the software. The format of the computer output, obtained from the WCADI programs, is suitable for inclusion in the design report to be submitted to the client or project authority, i.e. it can be in the form of standard engineering drawings and ASCII files that can be converted into word-processing files.
WCADI is menu-controlled, enabling the user to obtain easy access to the different stages of the design process. Changing certain input data does not require repetition of the entire design process, merely correction of the particular function. The input and output commands use familiar irrigationterminology. If the design engineer requires customising the wording of commands, the change can be executed through the DOS program EDIT or any other word processing programs that enables reading and writing of ASCII text files.
WCADI can be run in either SI or British units. The user must, however, pay special attention to the dimensions of input and output in each function as they appear in the tables. The user can change to the other system of units at any stage; previously entered information, as well as further calculations, will be displayed in these units. All data is, however, stored in SI units in the computer memory. All numbers in the equipment database are stored in SI/British according to the chosen unit.
Co-ordinates are stored in cm, flow in m3/hr or l/hr and pressures in m.
In output and input, the units are as per the following table:
When you start up the program, you obtain the initial screen. The central part of this screen is divided into two sections: Menus, and Information Panel. Use the mouse or left arrow (<-) and the right arrow (->) to move between the menus. A submenu appears for each menu except for the graphics menu which leads to the graphical screen.
The HELP description for the initial screen itself can be accessed with the F1 key. The user can get HELP description on a specific function by entering that function and pressing the F1 key.
Move the cursor to the required menu on the screen and select the required submenu in that menu by left clicking the mouse or by pressing the ENTER key on it. You can also activate a menu or submenu (or a function) by pressing ALT + the underlined letter of the name that appears for that menu or submenu item. At the bottom of this screen you see: Project name and path ,Case ,and a place for printing information’s for a specific function .
The MAIN menu consists of the following submenus :
5 MAIN PIPE
6 BLOCK DESIGN
7 NETWORK ANALYSIS
Eight options are available to define actions:
New: After you press on this item, a form appears to enable you to enter the location and name of the new project .After that, you enter the data for this project. The name of the new project will be added to the table of Projects and the new project will become the current project, emitters data file, pipe files and note files(*.NOT) are copied from the default directory.
Open: The user selects the project he wishes to work on. A graphical view will appear for the selected project, then he presses OK. This will become the current project. Projects done in an old version will be automatically converted to the new version.
Case: To change to another project case. The user selects or types a new case he wishes to work on. A graphical view (for mainpipe, network or both) will appear for the selected case, then he presses OK. This will become the current project case.
Copy: To copy all or selected items from a project to the given project. After you press on this item, a form appears to enable you to enter the location and the name of the project to copy from and, also, the project to copy to and the items to be copied (including the selection of the case, if enabled for the selected items ).
Delete: To delete all or selected items from the selected project. After you press on this item a form appears to enable you to select the location and the name of the project, and the items to be deleted (including selection of the case, if enabled for the selected items ). A graphical view will appear for the selected project.
Backup project: When entering this function the following dialog-box appears: This function allows the user to force the software to automatically make a copy for the working project in the place and cycle (in minutes) he determines. To disable this utility the user enters value of zero for the cycle.
Exit: Completely ends the work on WCADI Software. Any project listed in the table can be saved to or retrieved from disk, using windows explorer or any other way of copying directories and files. The project named “Default”, can be accessed to enter default values for all relevant functions of the design menus. The default project is not a project in itself, it only contains default parameters and other values. When a new project is defined for the first time, these default values will then be transferred to the new project.
Print target: In this dialog-box you select where to send the printing, to the printer or to an ASCII file. If printing is to be sent to an ASCII file, type a file name with or without an extension (e.g. PLANT1.PRN). Set the append or replace option. The append option, indicates that, the printing is to be appended into the existing ASCII file), while the replace option, indicates that, the printing is into an empty ASCII file). If printing is to be sent to printer, the name of the currently assigned printer, will appear and the user may click on the selection button, in which case the following dialog-box appears:
In this dialog-box you select from the list, the printer to which you want to send the printing, and the number of copies required.
Note: The # characters from left input filed, allows you to set the number of characters to skip from the left side when printing, for both cases printer and file.
