CEDRA-AVwaterTM enables the
engineer to define the geometric configuration, establish the
materials inventory of a water distribution network, introduce
supply and demand loads, perform analyses and display pertinent
results in graphic and/or tabular format. Storage tanks, pressure
regulating, sustaining and open/close valves, pumps, meters, etc.
can be included in the water distribution model. Extended period
simulations which adjust liquid levels in tanks over a user-specified
simulation period may be modeled. AVwater users can perform Fire
Flow analyses with node and pipe summary tables being created
facilitating the system adequacy determination, as well as, Dynamic
Water Quality modeling which tracks the fate of a dissolved substance
flowing through the network over time. CEDRA AVwaterTM offers the engineer an ArcView®
GIS and ArcGIS® interface to the U.S. Environmental Protection
Agency's EPANETTM Version 1
and Version 2 modelers, thereby integrating modeling and GIS technology.
The University of Kentucky's KYPIPETM
modeler is not supported nor provided.
In addition to the modeling tools, CEDRA AVwaterTM provides functionality for editing
attribute data using customized dialog boxes. The CEDRA-DataEditorTM extension, which is included with CEDRA
AVwater, enables the user to identify the specific themes and
attributes which the user can edit. Quality control and data verification
tools are included with the CEDRA-DataEditor extension to ensure
that the database is properly maintained. The customized dialog
boxes, which the user defines, are established without having
the user write any Avenue, Visual Basic or other programming language
software. With a simple point and click, CEDRA DataEditor users
are able to edit and maintain their tabular information without
having to start and stop table editing sessions.
CEDRA AVwater when utilized with any of CEDRA's geometry software, CEDRA AVcad, CEDRA AVcogo, CEDRA AVland or CEDRA AVparcel, provides the user a package that integrates Modeling, Mapping, Data Maintenance and GIS in a single common desktop environment. As such, the need to move data from one software environment to another is eliminated because ArcView is used as the common desktop environment. CEDRA AVwater users are able to begin and end projects entirely in ArcView.
ArcGIS users should check out the CEDRA-ArcView3-Tools toolbar. This toolbar offers a number of selection tools which will increase productivity by at least 30%. This is accomplished by reducing the number of clicks that are made in performing typical selection operations. ArcGIS users who have previously worked with ArcView GIS will definitely appreciate these tools.

Printing Capability for ArcGIS
ArcGIS® users have the ability to print the active data
frame using the Print Data Frame command, which is available in
the CEDRA-DataFrame-Tools toolbar. The Print Data Frame command
differs from conventional ArcGIS printing in that the user is
able to control: (a) the map scale, (b) the map area to be printed,
(c) the location of the map on the paper and (d) optionally, whether
a data frame, which contains a map sheet border, should be included
or not in the map.
As most ArcMap users have realized, within an ArcMap document file (.mxd) all data frames share the same layout. This causes the difficulty of when the layout view is activated all of the data frames in the document file appear in the layout, which for some applications is not what the user wants. The Print Data Frame command will print the active data frame, from data or layout view, ensuring that: (a) the desired map scale is preserved, and (b) all other data frames do not appear on the plot. This is achieved by programmatically positioning all data frames, other than the active data frame, in the document file outside of the user specified sheet limits (Paper Size parameters). In so doing, when the layout view is activated the only data frame that appears in the layout view is the active data frame.
This capability allows the user to have a single document file that contains many data frames with each data frame containing a complete drawing sheet. Without the Print Data Frame command the user would have to: (a) create separate document files for each drawing sheet or (b) manually reposition all data frames, other than the active data frame, outside of the sheet limits.
In addition, users have the ability to operate in another mode
of map preparation. The first mode, which was described above,
is when a single data frame contains the entire map to be printed.
The second mode is where one data frame contains the map contents,
while another data frame contains the map border (title block,
sheet border, etc.).
The Print Data Frame command accommodates this scenario by providing the Include Data Frame matching the Paper Size option. When this option is checked the Print Data Frame command will position the active data frame according to the specifications in the Data Frame Size and Position parameters area and will include in the plot the data frame whose name is either 11"x17", 24"x36" or Custom, depending upon which Paper Size is active. This approach enables the user to create a single map border, placing it in a data frame using one of the following; 11"x17", 24"x36" or Custom as the name of the data frame, and generate multiple maps without having to load the map border into multiple data frames.
DXF Export Capability for ArcView GIS and ArcGIS
ArcView® GIS and ArcGIS® users have the ability to create a DXF file, from within ArcView 3.x or ArcMap, for all visible features in the current map. Unlike other DXF export utilities, which process only one theme at a time, the CEDRA DxfExportTM extension processes all visible themes (shapefiles, personal geodatabases, enterprise geodatabases and coverages) in the current map. In addition, the CEDRA DxfExport utility will process annotation features and graphic text elements. As such, a DXF file created by this utility can include features and text. In processing the visible layers in the map:
- If a theme has selected features then only the selected features will be processed, if there are no selected features then all features in the theme will be processed, this includes point, polyline and polygon features. If the option Export Features displayed in the Current Extent is selected then all visible features in the current view will be exported regardless of the feature's selection state.
- If a theme has labels, the labels will need to be converted into annotation, using the Convert Labels to Annotation... command, in order for the labels to be exported. The labels that are converted can be stored either in a personal geodatabase or in the map, depending upon the user's preference.
- If there are selected MARKER, PEN, FILL and/or TEXT graphic
elements then these graphic elements will be processed (if the
user desires). If the view does not contain any selected graphic
elements then no graphic elements will be processed. In exporting
graphic elements note the following:
- All of the selected Marker elements will be placed in a layer called GrapMrkr,
- All of the selected Pen elements will be placed in a layer called GrapPen,
- All of the selected Fill elements will be placed in a layer called GrapFill, and
- All of the selected Graphic Text elements will be placed in a layer called GrapText.
- The name of the theme will serve as the name of a layer in the DXF file.
- Non-alphanumeric characters in a theme name are converted to the underscore character (_).
- The user has the ability to select one or more attributes, from a choice box that appears in the Create DXF File dialog box, for inclusion in the DXF file, if desired. When exporting attributes, the selected attributes will appear as "blocks" in the DXF file. These blocks will appear at the midpoint of the feature and the name of the block will be B_xxxx, where xxxx denotes the name of the layer the feature resides in. All of the attributes associated with the block will be listed vertically, one under the other. The ability to export attributes is important because: (a) it enables the user to transfer non-graphic information (attributes) into the DXF file, maintaining the association of the non-graphic information with the feature and (b) provides a mechanism for the user to maintain symbology and line styles. Regarding the latter, symbology and line styles, in the GIS classifications are based upon attributes, by exporting the attributes which the classifications are based upon, the user has the ability to regenerate the classifications in the system in which the DXF file is being read into. This, of course, is dependent upon the software which is reading the DXF file, that it has the ability to change symbology and line style using information that is stored in a "block".
|ArcMap - CEDRA-DxfExport Dialog Box|
As can be seen by examining the dialog box above, the user is able to:
- Control the name of the DXF file that is created. The Browse... button enables the user to use a standard file navigation dialog box to control the folder where the DXF file will be written to, as well as the name of the DXF file.
- Specify whether the theme names are to be trimmed to 8 characters or not. If a check appears in the square to the left of this parameter, the names of the visible themes that are processed will be trimmed to a maximum of 8 characters. The first 8 characters of the theme name will be used.
- Specify whether selected graphic elements are to be included in the DXF file creation. If a check appears in the square to the left of this parameter any graphic elements that are selected will be included in the creation of the DXF file.
- Specify whether a DXF file for importing into the CEDRA I-series software is to be created or not.
- Specify which attributes if any are to be included in the DXF file as "blocks". If a check appears in the square to the left of this parameter all attributes which are selected in the choice box will be included in the DXF file as "blocks". There is no limit to the number of attributes that can be selected, and
- Specify whether the visible features in the current extent (view) are to be processed. If a check appears in the square to the left of this parameter then the only features that will be exported will be the visible features in the current extent, regardless of their selection state. In addition, if the Export Selected Graphics (Marker, Pen, Fill and Text) option is selected, all Marker, Pen, Fill and Graphic Text elements in the visible annotation group layers which are within the current extent will be exported, regardless of their selection state. The name of the annotation group layer will serve as the name of the layer these graphic elements are placed in.
- Specify whether the data that is exported is to appear in the same coordinate system as the current view (data frame) or not. If this option is not checked, the data that is exported will be in the coordinate system of the theme's (layer's) source data. If this option is checked, all data that is exported will be in the same coordinate system as currently displayed in the data frame.
ArcView 3.x Tools for ArcGIS
ArcGIS users who have worked with ArcView GIS will notice that the commands shown below: (a) do not operate the same in ArcMap as they did in ArcView or (b) are just not a part of core ArcGIS. These commands did not provide GIS functionality but they were an essential part of how ArcView GIS users operated in the ArcView 3.x environment. To ease the transition to ArcGIS, CEDRA's ArcGIS based software includes the CEDRA-ArcView3 Tools toolbar. This toolbar enables ArcGIS users to interact with ArcMap in a manner similar to how ArcView GIS users operated in the ArcView 3.x environment. For users who have never worked with ArcView GIS, these tools provide an easier and more flexible means of interacting with the map.
