I wasn’t precise enough… Technically it can produce 3D output and it does produce 3D output. However the Z values of the vertices is fulfilled with zeros (at least in case of multipatch and multipoint inputs). Which is not exactly 3D any more if the input features are several thousand feet above the reference surface. But yes, technically it is 3D. So it is already offered, but it’s never implemented and never going to be implemented. (Reading about something in a manual is helpful, but not enough. Someone have to try it in the reality) ...

I think the triangulation method in ArcGIS Pro was replaced by a different one which can’t handle the true vertical polygons. In this case every second triangle has a different winding and that’s why the face culling removes them alternately. The true vertical polygons were always problematic and not fully supported—especially in arcpy and ArcSDE. I can’t provide you a solution, just a workaround: run a “Layer 3D To Feature Class” against your shapefile in ArcScene. It would result a multipatch feature class which rendered always correctly—even in ArcGIS Pro. If you can try to make triangulated or ring-based multipatch surfaces from your cross-section data.

Hi Martina, Your model is probably not georeferenced, and “sitting” somewhere around the origin of the coordinate system, which is usually below the ground, so the model must be covered by the elevation surface. Go to the Table of Contents, double click on the “Scene” on the top of the panel. This would trigger to pop a new window up, called “Map Properties”.  On the left side of this window select “Elevation Surface” from the list. On the right panel of the window enable “Allow navigation below ground”.  Open up the drop down list on the bottom of this panel called “Elevation surfaces”. There would be only one elevation surface with the following location: http://elevation3d.arcgis.com/arcgis/services/WorldElevation3D/Terrain3D/ImageServer (which is the default). Remove this elevation surface with the red ‘×’ on the right side. Press “OK”, select your model layer, right click on them and select “Zoom to Layer” and voila… Be sure that your layer is in the “3D Layers” group.   Ákos Halmai ... View more

I got a building model in kmz with a collada model inside. It was exported from a CAD software called ArchiCAD. Importing a collada via “Import 3D files” results a single (multipart) feature per model. I’d like to make a better visualization in a local scene with the help of the range tool (remove rooftop, slabs etc. in an animated way), but to achieve this I need multiple features—logically or geometrically separated from each other. That’s why I tried the “Multipart to Singlepart”.  This tool produced me always a geometrically correct (or at least acceptable) result. However the textures are gone—because the “Multipart to Singlepart” has a no information how to separate logical groups in the model so the textures should be recreated or at least remapped, so the “Multipart to Singlepart” have to follow the rules are mentioned in the help. So this experiment is over, I have to import the model as BIM IFC and every problem would be resolved immediately. ... View more

It is „Cruiserweight” version of Drone2Map. It supports drone, satellite, scanned and digital aerial imagery. It can produce DSM, DTM, ortho, colored and classified point cloud (for example buildings). The images are stored in a mosaic dataset and every processing step is available as a geoprocess. So you can run a whole photogrammetric process from python or Model Builder. These geoprocesses are also available in ArcMap. ... View more

Now, it’s working properly in ArcGIS Pro 1.4 alpha 4. Thanks! It’s a big help for us. ... View more

There’s a variable called inRing, defined as a new List of IPointCollection, where the List is coming from the .NET’s Generic namespace. If you define such a list there is nothing inside, it is an empty container with zero instances in it. It’s not like a predefined array with exact number items. It’s totally empty. First, you should add an object (witch implements the IPointCollection interface) to the list with the inRing.Add method. This would be the 0th item in the list. After that you can add a point. However your solution seems complicated. Applying the IEnumVertex interface on the internal rings is probably easier. Ákos Halmai ... View more
