Hi, If you can generate the models in CityEngine, they are generatable. Models can only not be generated if : a] No rule is assigned at all b] No valid Start Rule is defined c] If the CGA code contains errors. Can it be that only the visibility is off in the WebScene or set so during export ? Did you try with the newest WebViewer 3.0 already ? Let me know .. matt ... View more

Well, the theory is very simple to this problem: Once you have split all floors, you split off the door on the first floor. then, the 'rest' shapes or that split plus all upper floor facades all are forwarded to the same rule that creates the windows .. Maybe it's a good practice to code this from scratch instead of trying to understand existing code.. That can sometimes be a bit tedious. Does that help a bit so far ? matt ... View more

Hi, These errors come up if you assign a rule that does not have a specific Start Rule to a shape with that defined Start Rule. E.g. If you have a shape with: Rule File : a.cga Start Rule : XYZ But the content of a.cga is : A -->     B. Means the rule XYZ is not defined in the rule. This now means that you need to clean all cases where this happens. But that should not be too much work. Ok ? matt ... View more

Hi ! Glad you found a solution ! matt ... View more

ok, please try 2013 then. Just download the TRIAL version. It'll work with the 2012 license. http://www.esri.com/apps/Products/CityEngine2/index.cfm matt ... View more

Hi, Yes, let's keep in contact for these showcase things. For the image, maybe send me a PM, then I can try for you in 2013, if you're interested. Hopefully you can resolve the installation issue soon! matt ... View more

Hi, CGA starts on a shape and has no information about neighbors what so ever. This is a limitation of CGA currently. The only exception is occlusion queries ( see docs ), but those cannot query any other specific parameters of neighbors. The only way you can do this currently is using Python to inform your buildings that they touch each other and have a combined length of 60. E.g. also use these steps: Model Generation 1 : create no lights, but create reports Python: Evaluate reports and write attribute data ( e.g. 'is big building, thus add lights on top' ) Model Generation 2: pick up attribute, generate lights ! e.g. if you have an attribute called 'wasGeneratedAlready = 0', you know in CGA that you don't want to add lights but report. After Python wrote the attr as 1, you create the lights. [Note that all those 3 steps can be combined in 1 Python script, if needed. You'd be using the script based exporter in this workflow.] ...

Hi, I'd say some info was lost when exporting the file from ArcGIS. Maybe test the file by reimporting into ArcGIS and compare to the original coming from Civil3d. If it's the same, try updating to CityEngine 2013. It will work using the same 2012 license. Let me know if this makes things better. There were some terrain value reading issues in 2012 that are now hopefully all fixed. Cheers ! matt ps. was that you here ? http://prezi.com/g9m1ib0aye4w/gis-bim-infrawow/ cool stuff ! 🙂 ...

Hmm .. One other question .. (sry for the many questions) Are you using CE 2012 or CE 2013 ? If not 2013, try that one too, ok ? matt ... View more

Hi, When using 0,0,0 as offset, you KEEP the georeferencing data. you need to press the center button to center all near the cartesian origin. using 0,0,0 stores very large coordinate values, thus the 3d display runs into precision issues. Thus, the models look broken. What other export settings are you using ? Are you exporting one model per shape ? Maybe a few screenshots would be very helpful .. Let me know .. matt ... View more

contact your local distributor from where you got the license or download the new trial. cheers ! matt ... View more

In general, the answer to your question is no. This is not possible. For a simple, but logic reason. Because 1 crossing can be shared by both a huge street and a tiny street. So who 'wins'. What' I'd do [and that's now better possible in 2013] is use Python to find the 'widest' street on each street node, grab it's type and depending on that type, set the crossing parameters or Start Rule. But this can only done with Python ( or manually of course ). Note that CE 2013 will work also with you 2012 license. No reason not to update .. 😉 Note though that we strongly recommend to create a new Workspace for 2013 and leave the 2012 workspace. Just migrate the projects over. Hope this input helps ! Matt ...

Hi, This could be many things .. I need more details to give some input on this. Do you get some errors in the Log Window ? Is the dataset georeferenced ? Let me know .. matt ... View more

Hi, You're creating polygons which are exactly on top of each other, so-called 'co-planar polygons'. In 3d, it's not possible to just hide some polygons by 'layering' as e.g. in Photoshop or 'painting over regions'. When 2 polygons are coplanar, these display-issues come up. It's an effect called 'z-fighting'. The problem is that the graphics card tries do display both polygons ( both are valid of course ). so in some small regions, one polygon is shown, in an other small region, the other polygon is shown, causing that 'flickering'. That's a fundamental thing that cannot be solved. The ONLY way to fix this is to separate the polygons a bit spatially. E.g. move the floor polygons 1 cm up or move the white big polygon 1 cm down Shape -->     alignScopeToAxes(y)     t (0,-.01,0)     Done. Ok ? 🙂 ... View more

hi, 1] yes, this should all be possible 2] the satellite picture needs exactly the same extent as the elevation map 3] can you share the files with me so I can try myself ? Send me a PM if the data is confidential.
