Additional Comments

1. The model uses only imperial numbers in the calculation. There are metric values accompanying the corresponding imperial values for pipe configurations in the MATERIAL.INI file, but they are only for display in the program, and are only rough conversions. However, it is possible to change the imperial values to more precise figures.

2. To make additional material selection and configuration, MATERIAL.INI file can be edited. Refer to StormCAD Help; search with keywords “material, component” for procedures.

3. The model considers all gradually varied flow profiles: horizontal, mild, critical, steep and adverse slope, in combination with the subcritical, critical, and supercritical types of flow.

4. StormCAD can import .dxf files as background, but it can not be manipulated within the program. When exporting the layout as .dxf file, no parameters or attributes get imported along with the file. AutoCAD, however, identifies the blocks and annotations, separating them into different layers.

5. Constraint based design is possible, where the model can automatically design a system based on constraint parameters provided from the user. Parameters such as max./min. velocity, slope, and cover can be set, user can also specify to match pipe inverts or soffits at each node. Pipe sizing and invert design processes can be automatically done.
