You can specify if pipes, junctions or fittings that do not have any cost calculated should be included in the Cost Report in the Output Control. Open Output Control from the Analysis menu and click on the Format & Action tab. In the Cost Report Formatting area, check or clear the Don’t Show Object With Zero Costs option.

The areas on the Specification Window which are required can be highlighted by either pressing the F2 key or by double-clicking on a blank area somewhere on the Specification Window.
To check the properties of the objects connected to the one you are specifying, position the mouse pointer on the connected object's ID (listed in the specification window) and hold down the right mouse button.
The inspection feature saves time by displaying the properties of a Workspace object in a read-only fashion. To inspect an object, position the mouse pointer on the object and hold down the right mouse button.
Very large and complex models may be constructed by building smaller models and merging them together. It is a good idea to break the large system into logical parts where there are known boundary conditions (flowrates or pressures).
Flow direction arrows are for reference only, the actual direction being determined by the analysis and, if the direction is opposite the reference direction you've specified, values for flow, velocity and pressure drop will be negative. If you don't want negative values, simply select the pipe, press F3 to toggle the direction arrow and rerun your model. While this is fine for one or a few pipes, what if you have many pipes with negative flow values? Within the Workspace, open Select Special (on the Edit menu or by pressing F6). For 'Selection Type', select 'Pipe Output Properties', then 'Volumetric Flow...
