Rules Tab (Structure Properties Dialog Box)

Rule Set

This drop-down list lets you specify the rule set for the structure.

Use Values From Rule Set

This option lets you choose to override or accept the rule values as they are defined in the specified rule set. If you clear this check box, you can edit the rule values on this dialog box, and the structure uses the rule values as they are specified on this dialog box. If this option is selected, the structure uses the rule values as they are defined in the specified rule set, and those values display on this dialog box.

Pipe Drop Across Structure

This rule compares all pipes connected to a single structure and ensures that pipes enter and exit the structure at logical locations. For more information, see Structure Drop Rule.

Drop Reference Location

Determines the drop location by using the pipe’s invert, crown, or centerline elevation.

Drop Value

Specifies what the drop value is between the lowest incoming pipe and any outgoing pipe connected to the structure.

Maximum Drop Value

Specifies the maximum drop value between the lowest incoming pipe and any outgoing pipe connected to the structure. Note that this parameter provides validation only; it does not alter (move or resize) the part in the drawing in any way. It simply produces a rule violation on the part if the specified value is exceeded.

Maximum Pipe Size Check

This rules checks to see if pipes entering a structure have a diameter or width that exceeds a specified maximum value. For more information, see Maximum Pipe Size Rule.

Maximum Pipe Diameter or Width

For circular pipes, this parameter measures the pipe diameter. For rectangular pipes, it measures width. If a pipe diameter or width exceeds the maximum value, a warning is issued on the structure. Note that this parameter provides validation only; it does not alter (move or resize) the part in the drawing in any way. It simply produces a rule violation on the part if the specified value is exceeded.
