There may be some specialized tools for doing this otherwise, but with built in ArcMap tools this can be done even with multiple layers, you'll just have to get clever with erasing the correct sections at the correct times based on your extrusions. You'll end up with two version of your buildings where the 3D slice was erased. On the scene, point to the Oswald Tower multipatch building footprint until you see the green editing handle (sphere) in the middle of the footprint. Since the slice is a large block covering everything above (or below) your slice erasing everything from the buildings layer inside it will result in a building layer that has the respective opposites left. The Modify Features pane appears for the Edit Vertices tool. Once you have this large area that should be covering the upwards or downwards portions of your buildings you can use Difference 3D to subtract it from your initial building multipatch. I have an elevation raster that represents a valley, and a multipatch that represents a dam. Typically you would extrude it enough to cover the entirety of your building features. If you can publish those as raster layers, Connector can recognize and will let you bring in as ground imagery. Keep in mind for fairly advanced features you may want to check that they are closed properly with tools such as Is Closed 3D and Enclose Multipatch, otherwise their could be issues with calculations later.įrom here, you can use default capability by taking your "slice" layer which I'm assuming is a 3D polygon and extruding into two versions- upwards and downwards (don't forget to multipatch the outputs as well). Only rasters can be brought in, via Connector for ArcGIS, as Ground imagery or raster. The polygon entities represent billboards. Which will ensure they are in a proper 3D format for calculations. Ive got a polygon feature class with z values enabled. What can typically be done is for you to convert your extruded layers into Multipatches using the tool 3D Layer To Multipatch. One solution is to rasterize the polygons and drape the rasters, as is done on-the-fly in ArcGlobe. The portion of the TIN surface within each polygon is extracted as a multipatch-based feature. ![]() I don't believe ArcGIS has a default tool for "slicing" in 3D. Interpolate Polygon To Multipatch produces a multipatch feature class using a TIN and a polygon feature class as input.
