Hidden Line Model Graphics Style
The Hidden Line command displays the image with all edges and lines drawn except those obstructed by
surfaces. This command affects the current view only.
Displaying Intersecting Geometry with Hidden Lines
If the model includes intersected geometry (for example, an extrusion passing through a wall surface), Revit
Architecture does not create new edges along the lines of the intersection. This may result in incorrect hidden
line removal during export. If you attempt to export a view of the design with hidden lines turned on, you
may see unexpected results when you open the view in another CAD application. See Hidden Line Model
Graphics Style on page 202.
To see all visible lines, Revit Architecture recommends that you first create an opening in one surface before
passing another surface through it. See Defining Wall Shapes or Openings on page 591.
