Hi Sean, to solve your task, please use the geometry.isRectangular (geometry Functions) function. Synopsis bool geometry.isRectangular(float tolerance) Parameters tolerance The tolerance in degrees for deciding if an angle is a right one or not. Returns true if all faces of the current shape's geometry consist of 4 vertices and contain only right angles, false otherwise. Angles in the range [90-tolerance, 90+tolerance] are considered to be "right".

Hello Tianfang, Thank you for your report. Can you please specify, what exactly happens when you import the DEM as an Terrain into a CityEngine scene? Is there any error message displayed? For texturing the DEM a second image file is used. For an example please see the attached image.

Hello, Thank you for your request. Regarding attribute search, there is no more functionality than described in the corresponding help section: Use CityEngine Web Viewer—ArcGIS Online Help | ArcGIS So please make sure, that all the classification the user might need (like "FLOORCOUNT < 2") is added as an attribute, before exporting the web scene. Since there is no official support for a "proper DB query", the only way is hosting the Web Viewer yourself and modify the search code. But this needs extensive programming knowledge. 42471 - Host 3D Web Scenes

Hi Tim, Sorry to hear you had to change your hardware. The CityEngine team is committed to support ATI hardware. So it would be very helpful to us, to get the scene, that creates the crash on opening.

Drew, thank you for the reply. My tests with World Creator have shown, that it may help to convert the 16bit Tiff from grey-scale to RGB. For data with 16bit per channel, an image tool that can handle this bit depth is required. If there is no 16bit editing support, most of the tools will downsample the data to 8bit on import.

Hello Anete, What is the exact error message you receive? In the message above "[1905.2194, 2139370.5, 1209.4117]" hints, that the problem is in the y-direction (this means up in the CityEngine native coordinate system). Did you try to import the FileGeodataBase into an empty CityEngine scene? Is the error then still occurring?

Hi Aida, I'm answering on behalf of Eric and Cheryl. Unfortunately the facade wizard of version 2015.0 is affected by a bug, that does not show the texture. Please upgrade to the latest version (2015.2) to use the facade wizard. Sorry for your extra effort. Thomas

Dear Nirdesh Singh, CityEngine can export models in the KML format. KMLs store location data in the geographic WGS84. 3D models are also stored in the COLLADA interchange file format. Models | Keyhole Markup Language | Google Developers If that is not suitable for you needs, than the XML file structure of the could be extended by adding additional tags. This can be achieved by a python callback function called for each shape after generation. http://cehelp.esri.com/help/index.jsp?topic=/com.procedural.cityengine.help/html/manual/python/python_scripting03.html But of course this is an customization that does not adhere to the Collada specification.

Dear NIrdesh Singh, CityEngine only allows projected coordinate systems (PCS) as scene coordinate systems. Coordinate System Dialogs For importing base maps, it is important to know, that CityEngine does not support re-projection. Therefore the imported raster data needs to be in the same coordinate system as your scene. Importing Georeferenced Data Best practice for CityEngine is to use a national grid or UTM as scene coordinate system.

Hello Lahmer Belkacem Thank you for the data. I had a look at the DEM TIF you provided. The issue is, that it uses a geographical coordinate system for georeferencing. Unfortunately CityEngine only supports Cartesian coordinate systems for terrain layers. Please export the DEM again using "WGS 1984 UTM Zone 31N" coordinates (same as OSM file) for georeferencing. City Engine Help: Importing Georeferenced Data "No reprojection nor rotation is applied to image data on import. The image's coordinate system is used only as reference system for location, extent and unit (translate and scale transformation) for the image data during import. It is therefore important to have image data ready in the target coordinate system before importing into CityEngine." Thomas F

Could you please provide a use case for your feature request? The CityEngine team knows some special use cases, where this can make sense, but we are still collecting more... The C++ SDK can only provide a fraction of the CE python functionality, but here it is easier to open it up the externals IDEs.

Hi André, Thank you for this qestion. In default graph drawing mode, one wants the terrain be smothed to align to the network graph. But you are using a premodeled bridge as a base for the graph. This means the feature has to be deactivated. Settings for new streets can be controlled by using the Street Creation Settings dialog. To open the dialog, choose Graph → Street Creation Settings... from the main menu. There you have to uncheck the "Align terrain" option. For more details please refer the CityEngine Help on that topic: Creating and Editing Street Networks Manually Best regards

Hi Tim, Thank you for your comprehensive feedback! Based on your insights I have created users stories for futher improving the feature. I now understand that for your work, you need very high accuracy in shadow analysis. This means that the 3D models casting the shadows, also have to be very exact. Please understand that for CityEngine there was a decision made to only offer moth accuracy. I know, that in order to be more accurate the day and even the year (leap year effects, precession and nutation of the earth, ...) need to be considered.
