Hi, CityEngine uses Jython, not native Python, so I recommend you search first if this SqlAlchemy thingy is supported in Jython. Sorry, cannot help further .. good luck. M. ... View more

Hi Larry, I just asked one of the developers again about this and yes, there seems to be a bug. So I'll forward this again to be fixed asap. Thanks for reporting ! * * * Btw. I'd never use Collada to port georeferenced data, see here : http://forums.arcgis.com/threads/59442-FBX-export-%28models%29-to-3DSMAX Use kml instead, ok ? Matt ... View more

hi Alex ! Ah, I see. Then, the best option is to select the shapes as they are, assign no rule at all and in the geometry exporter settings under 'General', choose 'Export models if generatable, else export shapes' or 'Export shapes only'. Instead of exporting generated geometry, this way you export the shapes' geometry themselves. To export attributes too, you need to export to a format which supports attributed geometries, such as GDB or SHP. Possibly also DXF, but I never tried this myself. Can you try this ? Let me know.

Hi, The only thing which seems to be missing is that those trees miss the transparency. Means the basic geometry in ArcScene is the same ( just 2 intersecting polygons with a tree texture, but cut out with an alpha/transparency map). From my knowledge, that is a current limitation of MultiPatches which are stored in a geodatabase or by the tool processes them. In general what I recommend in this case is never export ArcGIS symbologies to CityEngine because they're not recognized as such symbols anyway. Just export the point markers and create the trees or other point features with rules. I'm not sure if this answers your question.. Let me know if this makes sense. ... View more

Hi Larry, Can you also post a screenshot how that looks in ArcScene before export ? It seems to me that ArcScene - when exporting - swaps the 'nice' models with simple 'billboard' trees. Let me know.. Matt ... View more

Hi ! The lat/long values are projected to CityEngine's cartesian coordinate system, thus the high vertex coordinate values. CityEngine stores all the vertex positions in cartesian coordinates. The projection is done with a library, but I'm not sure how, but I'm pretty sure we can not share this. I'd recommend you google how to do this if you need the code. Let me know if this is ok or if you need more info. Matt ... View more

In order to export generated footprints i need to convert them to shapes first but as soon as i do so, i loose colour or material information, everything joins into single shape. Why do you need to convert back to Shapes exactly ? Models are what's exported as final geometry, to what ever format. E.g. if you go to ArcGIS, you export MODELS to a GDB and in there, they're stored as textured multiPatches. Shapes are the starting point of CGA. Shapes can only be textures or non-textured, but have no other material properties ( no color, reflectivity, ..) Ok ? m. ... View more

Hi, Just copy-past the obj into the project's assets folder. From there, use it in CGA as a 3d 'asset' or drag-and-drop it into the viewport to use it as a 'static model'. Check out all tutorial videos to learn about the basics. http://forums.arcgis.com/threads/64843-CityEngine-Collection-RESOURCES-FAQ-HELP Ok ? m. ... View more

Ah, beloved interop.. Coming from Revit, I assume you export CAD buildings. Try going for Collada, Obj or KML (if the models are georeferenced), if possible. CE directly import such models as 'Static Models' in the asset formats Obj and Dae (Collada). This should give you the least pain. Maybe try Okino's 'PolyTrans'. Let me know if this helps .. Matt ...

I know it is really annoying, all those format wars and all the different interpretations by the different software packages. Really frustrating. We're trying to stick to the format standards for the assets ( dae / obj ), but it seems others do not care so much about that (e.g. inverting values). Thus, importing stuff into CE and going back to the target app sometimes is a pita. Actually not sometimes, every time. We've been working on the collada importer recently, so that should not be an issue. Matt ... View more
