I haven't posted a question in a while
I have not needed to show a portion of a ceiling to be demolished in Revit yet, but the day has come. I have a 2x2 lay-in ceiling and I need to demolish a part of it. In the CAD world, you would perhaps show the grid to be demolished as a dashed line. Well, in Revit it seems that this is not possible. The grid in a lay-in ceiling is obtained via a model surface pattern and you cannot use the linework tool to override its appearance And, we cannot specify the linestyle to be used in a pattern, so trying to create a special "demo" ceiling to represent it correctly is out of the question.
To demo part of the ceiling, I can use an in-place ceiling family with a void to cut through (or sketch the ceiling in pieces and demo the appropriate part). And I refuse to draw dashed lines...so not BIM! In this case it seems like we can model this condition accurately, but the representation of this condition on a set of plans is not there. The phasing and phase filters work on the perimeter of the ceiling, but not on the model pattern. Well, if I'm demolishing an entire ACT ceiling in a room, the dashed line woudn't show up because I have walls around it, represented by solid lines
So I guess I'll have to resort to showing a filled region to define the ceiling area to remain. I kinda answered my own question, but I was hoping to hear what other users are doing and hopefully, someone will also benefit from this post as it's not THAT unusual of a condition. I'm also hoping someone from Autodesk is reading our forums on this nice Sunday morning
