This rule is intended for laying out pipes in a pressure-based pipe network where pipe levels are determined according to a specified depth below a terrain.
This rule ensures that the minimum cover is met along the length of the pipe, and also validates that both the minimum and maximum cover values are not violated along any length of the pipe.
Parameters
The following parameters govern the behavior of this rule:
-
Maximum Pipe Cover. Specifies the maximum cover of soil over the pipe, based on the surface being referenced by that pipe. If the pipe cover exceeds the maximum cover value, a rule violation occurs for that object. 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.
-
Minimum Pipe Cover. Specifies the minimum cover of soil over the pipe, based on the surface being referenced by that pipe. During layout, a pipe will be created that attempts to maintain the minimum cover. If the pipe is edited so that its cover is less than the minimum cover value, a rule violation occurs for that object.
Note: For spanning pipe labels Start Cover will display the cover at the beginning of the span of pipes that comprise the spanning pipe label. End Cover will display the cover for the very end of the span. The start and end of the spanning pipe label depends on the order in which pipes where selected when creating the pipe span.
