Meaning: The pipe is shorter than the preferred minimum pipe length defined in the piping specification's Minimum Pipe Length Rule for Random Length Pipe rule. For example, if the minimum pipe length for 6” pipe is 3” and the preferred minimum pipe length for 6” pipe is 4”, and the user creates a straight pipe feature that is 4” or up to 3”, a Preferred Minimum Pipe Length Violation entry is generated on the To Do List.
Recovery: Increase the length of the pipe, or modify the rule to allow the shorter length pipe.
