I have been trying to use the Split Buildings Into Floors tool from the Local Government 3D Basemaps solution.

Is there any documentation on using this tool beyond that found at http://solutions.arcgis.com/local-government/help/local-government-scenes/get-started/floors-creatio...?

The picture below suggests that there might be where it says "See the Local Government 3D Basemap solution help documentation for more information on how to create a Building Space Use table" but maybe that is what I am already looking at.

Help for Building Space Unit Table

What is confusing me is how to reconcile the values that I see for building 285 in Philadelphia_BuildingTable.xls with the building volumes that I get from running Split Buildings Into Floors followed by Extrude Attributes on the Philadelphia test data provided.

Building 285 Floor Volumes

In the spreadsheet it has:

Tier 1

If Tier 1 shows in red then how do the values correspond to it?

Tiers 2 & 3

If Tier 2 shows in blue then how do the values correspond to it?

If Tier 3 shows in yellow then how do the values correspond to it?

Where does the RoofHeight of 20 show up?

Hi Graeme,

There is no tier 4 defined so tier 3 gets the rest of the building.

Hi Graeme,

You are looking at the correct documentation. Let me try and explain how it works...

Tier 1 has 1 floor of 58 feet with color #FF2C36

Tier 2 has 10 floors of 12.05 feet with color #83C4EE

Tier 3 has 7 floors of 12.05 feet with color #FFD958

and so on....

Roof height drives the vertical space that does NOT get split into floors. Typically you don't want to split of AC units and other stuff that is on the top of roofs. Or pitched roofs etc.

Let me know if you have any other questions.

Thanks Gert

I think that explains Tiers 1 and 2, and what happens with the roof, but in my XLS row and Picture for Tier 3 there are 7 and 14-15 floors respectively.

Thanks Gert

It's been about 5-6 weeks since I spent an afternoon looking at this, and it may be a while before I get a chance to test it, but I think your explanation now makes sense so I'm happy to assume that you have filled in the gaps of my understanding.
