This is the first of what is hopefully many more Revit Tips to come. Something that I’ve seen in some projects I’ve worked on lately is using filled regions to poché walls and floors in section views. DON’T DO THIS! Besides taking a large amount of time to initially create, filled regions are not going to update as you add or remove walls, windows, etc. So how do you poché your walls? Easy.
There are two tools that you will use to make this happen, Visibility/Graphic Overrides and the Join Tool.
I think the reason that you would try to used filled regions to poché walls is because you don’t fully understand how Revit displays objects. Revit uses a hierarchy of graphic settings to determine what to display.
On the most general level are the project’s Object Styles. You reach these by going to Manage -> Settings -> Object Styles. I could write a number of essays on what you can do here, but right now we will just focus on the Walls category. The main walls category by default has 3 sub-categories. For these 4 category/sub-categories you can set the line weights/color/pattern for projection and cut views as well as the default material. This is where we could bump up the line weight for cut walls to make our elevations read clearer.
