Parts Overview

Part elements in Revit support the construction modeling process by letting you divide certain elements from the design intent model into discrete parts. These parts, and any smaller parts derived from them, can be independently scheduled, tagged, filtered, and exported. Parts can be used by construction modelers to plan delivery and installation of pieces of more complex Revit elements.

Parts can be generated from elements with layered structures, such as:

• Walls (excluding stacked walls and curtain walls)
• Foundation Walls
• Floors (excluding shape-edited floors of more than one layer)
• Roofs
• Ceilings
• Structural slab foundations
• Slab Edges
• Fascias
• Gutters

Parts can also be generated from the following categories of loaded or in-place families:

• Structural Framing
• Columns
• Structural Columns

The elements you create parts from can be in the current project or in a linked model.

Parts are automatically updated and regenerated when the original element from which they are derived is modified. Such edits might include adding/removing layers, or changing wall type, layer thickness, wall orientation, geometry, materials, or openings.

Deleting the original element from which parts have been derived will delete all those parts as well as any parts derived from them.

Copying the original element from which parts have been derived will copy all the associated parts as well.
