These rules govern primarily how a structure object is placed and sized during object creation. They also can determine the elevations of connected pipes. There is also a rule to flag pipes that are too wide to connect to a structure.
Just like pipe rules, when structure rules are violated, a warning icon is displayed for the object in the Pipe Network Vistas (Panorama window or Toolspace item view), and on the Rules tab of the Structure Properties dialog box.
The following sections describe the standard rules associated with structure objects.
Topics in this section
- Pipe Drop Across Structure Rule
This rule compares all pipes connected to a single structure and ensures that pipes enter and exit the structure according to the specified drop value.
- Pipe Drop Across Structure Rule Examples
The Pipe Drop Across Structure rule applies in a variety of scenarios.
- Maximum Pipe Size Check Rule
This rule checks to see if pipes entering a structure have a diameter or width that exceeds a specified maximum value.
- Set Sump Depth Rule
This rule sets the sump elevation of junction structures based on the user-specified parameters and the invert elevations of pipes attached to the structure.
