Exactly how were they created? Can you provide some screen captures? (You might need to create more complex 3D solid object features in a 3rd party 3D drawing software as ArcGIS is very limited in this area. I suspect your polygon multipatches do not fully enclose a volume. Intersection also succeeded without errors.

(See screen captures below) I then created some circular polygons, extruded them and converted them to multipatch features. Intersection succeeded without errors and produced expected results. I was also able to calculate volume of the spheres. I tried running an example with spheres and created 2 intersecting multipatch feature classes. Personally, I have not had a lot of success using 'Extrude Between' with complex surfaces) (Unless you extrude between 2 TIN surfaces which should produce a closed multipatch. Multipatch features created with the Interpolate multipatch to polygon (using a surface) tool can likely not be closed.

To close a multipatch feature, it must completely enclose a volume. Indeed, after mucking about with this for the last few days and realizing that ESRI's own tools create multipatches that can't be used with many 3D Analyst tools, an alternative would be preferable.ĮTA: What I'm ultimately after is to calculate the volume of space that is occupied by (for example) cubes with a an attribute value of X where they intersect spheres with a value of Y (of course, I have lots and lots of values of X and Y to run). Any alternative software solutions would be great too, I'm not tied to ESRI. So if anyone knows a way to reliably create closed multipatches from 2D polygon layers and/or center points (with attributes describing the dimensions), let me know. I haven't tackled converting points to 3D cubes yet. That also produces multipatches that are not closed and therefore useless. Which tells you to symbolize the points as spheres, using an attribute as the radius, then use the 'Layer 3D To Feature Class' tool to make them into multipatches. I tried converting my points to spheres, using an example I found on ESRI's site here: I've tried converting my one polygon layer (8 features) to a Multipatch both by extruding it in Arcscene using its height and converting that to multipatch and also using the 'Extrude Between' tool, and they both produce some multipatches that are closed and some that aren't. The main problem I'm having so far is that the 3D Analyst Union and Intersect tools refuse to operate on Multipatch features that are not 'closed', and I can't seem to force ArcGIS to create Multipatches that are closed. I'm pretty sure the 3D Union and 3D Intersect tools only work on Multipatch features so I need to convert all of them to Multipatch features first. Some are points (thousands of them, which each represent a 3D volume, either a cube or a sphere, the dimensions of which are attribute values), some are polygons. In a nutshell, I have several layers I need to intersect or union in 3D. According to all the documentation I've read, 3D Analyst should be able to do what I am trying to get it to do, but I am running into problem after problem and I'm almost ready to give up and find a simpler way to answer the question I'm being asked.

It also includes example code you can reference, or even use directly, in your development efforts.I'm on ArcGIS 10. This whitepaper provides in-depth directions and methods for the third option – creating multipatch geometries through ArcObjects programming.

By importing data from existing models, such as SketchUp, COLLADA, 3D Studio Max, or OpenFlight.

Through certain geoprocessing tools, such as Extrude Between or Layer 3D to Feature Class.

Multipatch features cannot be created interactively using the standard editing user interface, but rather must be constructed by using one of the following methods: The multipatch geometry type is used for storing 3D objects - such as buildings, geological bodies, 3D no-fly zones, etc – in both the geodatabase and shapefile formats. This document demonstrates how you can create the multipatch geometry via ArcObjects. The multipatch geometry type, a geographic information system (GIS) industry standard developed by ESRI in 1997, is used to define the exterior shell representation for 3D objects.
