Partial Structure Display

Use Document > Partial Structure Display to set these preferences; they will be applied to the current window and can be saved separately for each view.
Entire Model: this is the default setting. All parts of the model are displayed.
Without Finishes: Model is displayed without:
Core Only: Displays only the structures defined as “Core” (applicable to complex or composite structures, and columns having a veneer)
Core of Load-Bearing Elements Only: The fourth option considers all construction elements (not just composite/complex). This option will hide any elements you have classified as “non-load-bearing” or “undefined”.
