Suggestion - the pipe annotation size (both fitting and rise/drop) driving views in a project, to be driven by the value in the project, not the value the link, for piping that exists in the link.
Currently, the value as set in the link sets the size for all piping showing from the link into the current project / central. In case the value is different from the value as set in the local MEP Settings / Pipe Settings, piping single line annotation will show different size circles for linked vs. local piping. If the local MEP Settings / Pipe Settings value would drive both annotation size from both local ad linked piping, the single line representation would automatically be consistent.
