Edit multiple object data and properties using grid views.
Tutorial resources
These downloadable resources will be used to complete this tutorial:
When working with an open network, along with adjusting single network object properties from the property sheets, view and edit the properties of multiple network objects using grid views. Grids are spreadsheet-style data tables of objects in the network that are divided into groups, and each group contains grids for one class of object and related sub-objects.
To complete this exercise, import 1D Sewer Network.isfm and open it on the GeoPlan, or use an available existing network.
There are several methods to open a grid view for all the nodes in this network:
Regardless of the method used, all of the nodes from the network display in a spreadsheet-style grid window. The list of object classes is at the top of this menu, and it includes nodes, links, subcatchments, polygons, lines, points, and results.
If an object or objects are already selected, hold down the CTRL key while opening the relevant object grid window, and it will only contain the selected objects.
Note: When a grid window is active, in the menu bar, the Grid menu also becomes active and contains some additional features.
In the Grid window, columns can be reordered, and whole columns or sections of data can be cut, copied, or pasted. Values can be modified individually or in bulk.
For example, to increase all values in a column by 5%:
In the grid, the values adjust accordingly.
If Auto-flagging is turned on in the toolbar, the column just modified now has the flag color. To change a flag:
As another example of easily adjusting values, increase the pipe width by 150mm:
Notice at the bottom of the window that tabs for different types of links appear.
This can be useful to quickly test the impact of upsizing pipes.
In large grids, the Find tool makes it easier to locate specific columns:
These functions can be carried out on the entire column, a selection, or an individual field.
Note: Use the Undo button to revert any changes that have been made. To remove all changes since the last commit, there is a Revert all changes option, which can be found by right-clicking on the network icon. Changes cannot be recovered once this option has been selected.
