Revit gives the user a number of ways to override the display of an element.
It may not always be clear which method “wins” over another method, but there is a visibility hierarchy.
This list may not cover every possible scenario but does include common overrides.
10 being the lowest and 1 being the highest using walls as an example:
Line Work Tool
Override Graphics in View > By Element > Halftone
Graphic Display Options – Silhouette Edges
Override Graphics in View > By Element
View Filters
View Depth – “Beyond” Line Style
Phasing Graphic Overrides
