Add elements

• Node: in Network, pick node and click on the canvas. Set demand and elevation in the inspector.
• Pipe: select Draw Pipe, click the start node, add vertices with intermediate clicks, and finish on the end node. Set diameter, length (if manual), and roughness.
• Pump: create a pump node or convert a link; assign gain or a curve.
• Tank/Reservoir: add the node and define level or head.

Edit properties in the inspector

• Select the element to open the right panel.
• Change diameters, elevations, demands, valve setpoints, or pump data.
• DW roughness accepts decimals and displays with 1 decimal place.
• Save and recalc to see the impact.

Quick examples

• Change diameter: pick the critical pipe, increase diameter, recalc; check downstream pressure.
• Adjust elevation: correct a node’s elevation; recalc to see pressure change.
• Add a pump: insert a pump on the main line, set a simple gain, run, and check if low pressures improve.

Editing tips

• Use Move to tidy node positions; topology remains intact.
• Use Undo/Redo in Tools to revert mistakes.
• After importing .inp, confirm units in Settings before editing.
• While drawing pipes, Backspace/Delete removes the last vertex and Esc cancels.
