Invisible boundary surrounding rotated railings, clashes with plan regions? Revit 2024.1

[jordanL24TZ]

I've placed a plan region on a plan to show the top of retaining walls with fences on top, however a fence (modelled as a railing) disappears.

I've checked worksets, filters, hidden elements, phasing, view range and have found why it's disappearing.

When the railing is rotated, Revit seems to draw a boundary around the extents of the railing and uses that to determine whether the railing is within the plan boundary or not.

I've added detail lines to the below images where this boundary would be.

Plan region is shown dashed green.

Within plan region extent:

Invisible boundary crosses plan region extent:

Is there a fix for this that anyone is aware of?

I'm not sure why this would be used to detect whether a railing is out of the view or not..

Thank you

The plan region should not touch the bounding box of the railing. Edit the plan region boundary and notch the corner.

Thanks for the reply. 

This isn't an option as the railing is quite long. That smaller railing was just an example.

To edit the plan region to fit the bounding box, it would cover the building and wouldn't work.

Then you might want to rotate the view so that the railing is not angled, create an the plan region then rotate the view back.  If that still doesn't works, you will need to to split the railing into shorter multiple railings, or use something else such as a curtain wall or a mass with repeating adaptive components.
