Building Footprints: What's entered in the "BuildingPart" field?

Question

Not finding much documentation on what to enter and how to utilize the "BuildingPart" field in the Community Maps layer.

When a single building is made up of different parts, I'm guessing something entered into this field indicates the polygon within a polygon can be designated a building part, multiples of which constitute a single building. What might that entry be?

Example #1:  A large building is internally divided into four similar sections. My intent is to show a single building composed of four sections.

Example #2: A large building has two sections with different building heights. While I'm able to enter the different building heights in the "Height" & "HeightUnits" fields if they're shown as different polygons, what gets entered in the "BuildingPart" field?

Hi @ScottFraser_Key-West

In your example 1

• Create four polygons, one for each section
• Set BuildingPart = 1 for all four
• Do not include a separate outer footprint polygon
• (Unless you want it for cartography — then set that outer polygon to BuildingPart = 2)

Example 2

Set:
• BuildingPart = 1 for both polygons
• Fill in Height and HeightUnits for each polygon individually
Esri’s 3D basemap renderer will extrude each part to its own height.
