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. If grouping by ObjectID then you will have the same number of entities - i.e one multipatch for each polygon. 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. You report that your 'output had the same amount of entities only they all were having the same geometry.' You can check whether the geometry is MULTIPATCH or POLYGON on the Feature Layer Properties -> Source -> Geometry. to import and transform different data formats into multipatch feature classes. 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. different types of datasets, including raster and vector files. We have tried to create a multipatch line representing the raster domain boundary by using the 3D Analyst tool Raster Domain and then converted this to a multipatch (shown with the red line). 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. Typically you would extrude it enough to cover the entirety of your building features. The Modify Features pane appears for the Edit Vertices tool. 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). Which will ensure they are in a proper 3D format for calculations. What can typically be done is for you to convert your extruded layers into Multipatches using the tool 3D Layer To Multipatch. I don't believe ArcGIS has a default tool for "slicing" in 3D.
