  1. Create Pipe Network from Shapefiles

To create a pipe network from Shapefiles, Shapefiles for either pipes or structures exported from analysis software or any GIS software shall be used, the shapefiles shall meet the following criteria as minimum:

·        Shall contain a unique field (unique ID),

·        Shall be a type of lines, polylines for pipes shapefiles, and

·        Shall be a type of points for structures shapefiles.

To create a pipe network from shapefiles, do the following:

1.      Use the command “CreatePipeNetworkFromShapeFile”or use the button “Create” under “Gravity Tools” tab in “Shapefile Connection” panel.

2.      In the creation dialog step 1, click the buttons to select shapefiles to connect to, and click “Connect”. Refer to Gravity Image 2.

3.      In step 2, write the network name.

4.      Select the part list.

5.      Check the “Snap pipe and structure tolerance” to connect pipes and structures within the tolerance value.

6.      Set the replacement characters for restricted characters. Refer to Restricted Characters.

7.      In step 3, set the pipes data mapping, the dropdown list contains all fields in the Shapefile. Refer to Mapping. Refer to Figure 4. Alternatively, import map using the “Import Map” button, for more information, refer to Export/Import Mapping Settings.

8.      In step 4, set the structures data mapping as well as done in step 3.

9.      In step 5, set the pipes sizes mapping by selecting the family and the size. Each size found in the fields mapped to sizes parameters (Diameter, height, length, and width) will be listed. Refer to Figure 5.

10.      In step 6, set the structures sizes mapping as done in step 5.

11.      Optional: the mapping settings can be exported to be used in creation of another network, for more information, refer to Export/Import Mapping Settings.

12.      Click “Finish”, an event dialog box appears to show the process progress.
