Curtain walls are geometrically complex objects that often have a large number of different elements, such as frames, panels, and window infills. The settings for these elements are defined in the curtain wall style and can be modified using Style Manager. However, there are cases when modifying a curtain wall directly on screen is more suitable:
When you have finished your onscreen edits, you have three choices:
Overrides you can set include assigning a different definition to a selected cell, frame, or mullion, and assigning a profile to a frame or mullion edge. Note that the definition or profile must already exist in the current drawing before you can use it as an override. For example, if you want to override a cell that has a simple panel infill with an octagonal window infill, you must first define the window (octagonal) style as a valid infill in the curtain wall style. Similarly, if you want to override a frame or mullion edge assignment in the curtain wall, the curtain wall style must contain the edge profile as a frame or mullion definition.
Overrides do not affect the Design Rules for the curtain wall style. However, you can transfer overrides to a curtain wall style if you want all curtain walls of that style to have the same overrides.
You can view a list of overrides that are currently assigned to a curtain wall from the Overrides tab of the Curtain Wall Properties dialog box.
