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

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.

Explode tool from Editor is not working (multipatch is not supported), Multipart to Singlepart GP drops the textures immediately.

Simple drones provide usually yaw, pitch and roll values for preliminary orientation. But ArcGIS Pro is waiting for omega, phi and kappa (which is more common in professional photogrammetry). Ákos Halmai

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.

If I’d like enter the optical parameters for a new ortho mapping workspace and I’d like to define the plain coordinates of the principal point of the measuring camera there is no indication for the unit or origin. Actually the adjustment report of an existing ortho mapping workspace helped me a lot: it says “… Position of the Principal Point is referenced to the physical center of the image plain. …”. And there is a table before this statement indicating the coordinates of the principal point is measured in millimeters. It would be quite helpful to indicate these information on the wizard’s GUI. But the real problem arises after that. If the position of the principal point is measured from the physical center of the image plain (center of the sensor) than the coordinates could be either positive or negative. But I can’t enter negative values at all. Same problem at the Konrady (or Brown-Conrady -- as the adjustment report says?) constants. Maybe I misunderstood something (?). Ákos Halmai

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

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

If “yes” than how? These images are “slice rasters”, a special type of medical remote sensing, so they can be interpreted as point cloud or series of rasters.

No matter! The “Intersect 3d Line with Surface” is still there…

There is a “Display” tab on the general “Options” window of ArcGIS Pro 1.3.1. and there are three antialiasing related setting: “Antialiasing mode”; “Text antialiasing mode” and “Enable hardware antialiasing”. The first two can be {None | Normal | Fast | Best}. If I change the first two to “None” (there is no antialiasing), then the third option “Enable hardware antialiasing shouldn’t have effect. But it has, especially on thin lines (typical antialiasing), at least in local scenes. I think I misunderstood something. These option are working separately and the first two is only for software antialiasing?

There is a “Display shadows in 3D” check box on the “Illumination” tab, on the “Map Properties” of a local scene in ArcGIS Pro 1.3.1. If I check it in every feature layer starts to drop shadow. Can I switch it off on a given layer? For example in BIM environment the multipatch feature class of the windows do not need any shadow casting effect. But the other feature classes do need. Is there a check box somewhere on the UI? (In the aprx file’s xml definition of the separate layers there is a <CastShadow>true</CastShadow> element to switch it on/off, but it isn’t the right way…) And also the animation path is also dropping shadow, however it shouldn’t drop shadow at all, because it is not participating in the scene.

There is a “Rotation” property on the “General” tab, on the “Map Properties” of a local scene in ArcGIS Pro 1.3.1. This value expresses the rotation of the whole scene. If I rotate the scene manually it changes on the following interval: ]-180; +180]. However I can’t enter negative values. Only positives are allowed. For example the rotation value says that the scene is standing on -26.5°and I want to enter manually -25° than I can’t. Then I have to calculate that -25°equals to +335°. And after pressing the enter I see -25° again . It’s tiring.

Yeah, I was the third who registered from Europe .

Thanks! I’ll wait for it…
