    Plan Regions vs. Families Visibility Issues

    MEP model with architectural link. Project is a row of townhouses, each section steps down from an end of the row by 18". Only three levels provided by architect. I would have put in at least eighteen. We are using plan regions in overall view of entire row. View range is set to the "master" unit and plan region view ranges set with an offset from "master" levels.

    We have a couple of fairly simple mechanical equipment families that are not behaving when near the limits of a plan region. No overlapping of plan regions and/or, apparently, anything in the families crosses the plan regions. In fact, the families are near a foot or more away from the plan regions. Not thoroughly tested yet, but it looks like when they are within that foot, they ignore the plan regions and use the overall view range and appear on both floors, because they cross the "master" level and don't appear on the level below when above the "master" level.

    Looking for a solution other than hiding in view. It is a viable option as this particular project is simple and small. Hiding objects would not take much time. A lot of our projects are utilizing plan regions and we seem to run into different issues with them for every project. Hiding objects is not always as quick and easy, especially for larger projects.

    I didn't set up the project, so I don't know all the particulars of why it was set up in this fashion. If more information is needed, I may have to do some digging for the logic behind some of the decisions, if you guys start questioning the methodology.

    Thanks in advance, as this has a few of us baffled.

    Double check that your family (or its nested components) don't have any reference planes beyond the element. If those cross a border it could change how view depth is interpreted

      Tried it. Although, a couple of them were close, it didn't fix the issue.

        Not sure if it will help but Families have their own cut plane that works in tandem with the cut plane in a project. You might try tinkering with that.

          Good idea and I thought that was going to do it but it didn't. I tried a few combinations but no change.

          I tried playing around with the overall view range but even when it is set below everything the equipment still shows within the plan regions even when it is totally below the limits of the region. It seems like this is a know issue and we are going to have to go with hiding elements per view. I don't like it but if it a bug with plan regions, then there may not be another way.

            Have you dug into the families themselves?
            I recently had some families from a consultant that had Reference Lines (or maybe planes, forget which) that extended below the Reference Level of the family.
            I trimmed them up to stop at the Reference Level and they showed up where they belonged.

                I did dig into the family and adjusted the reference planes ends close to the extents of the objects. I wasn't really concerned about the vertical ones because the issue is definitely related to the horizontal limits of the region. I've actually got three boilers in a line and as we bring the edge of the region close to each one it shows up on the level below.
