Sorry, fixed the URL.. My bad.

Hi Guillermo, that is a focus problem of the camera. Try using 'f' and 'a' to zoom to the selection or to all. This sometimes happens. Let me know if you can't get rid of it. Matt

Hi ! There's many example cities available and more content is produced. It's tricky to create rules that make everybody happy since everybody needs something else .. [[ So in general, it's still the best to learn CGA yourself, then you can create many many very efficient rules with it. I personally rather create code from scratch then taking somebody elses code.. ]] m.

Hi ! Can you post a series of screenshots so I see which steps you take ? (I need more details) Please let me know .. Matt

Hi ! I assume you know what happens with "--> Lot", those rules just forward the geometry to Lot. That's basic. So I guess your question is that LotCorner and LotInner are. These are 2 default 'StartRules' that are produced by the 'Dynamic City Layouts' system ( the street system ). 1] LotInner are Lots that reside within the Block, but do not touch a street. Create a Block, select each Shape and check the default StartRule on the Shapes. More on Street Start Rules here: http://cehelp.esri.com/help/index.jsp?topic=/com.procedural.cityengine.help/html/manual/is/create/streetshapes.html And on LotInner here: http://cehelp.esri.com/help/index.jsp?topic=/com.procedural.cityengine.help/html/manual/cga/rule_files/cga_rf_startrule.html 2] LotCorner shapes are created when you set the 'cornerWidth' parameter on a block with recursive or offset subdivision. This is a prominent geometry feature in e.g. Barcelona or Paris. I guess this will help you. Matt

Hi Bos, Sorry for the late reply. Yes, the tutorials are online here: http://resources.arcgis.com/en/help/cityengine/10.2/index.html There's also a video version for them. The videos were recorded on CE2012. The GUI did not really change since 2012, so we decided to not record new vids for 2013. Please find also more info on how CE works in the FAQ thread in my signature. * * * You'll find that one can not 'create rules from models', but that CityEngine is a procedural modeling application, where you always start on a shape ( usually flat, but can also be a 3d mesh ), to which a rule is assigned to get the model. Check especially tutorial vids 1,2,6. Ok as a start ? Matt

Hi, the main thing to know is that Unity does not really work with georeferenced datasets. For this, CityEngine has an export feature which you can use to move ( on export ) the georeferenced datasets to the cartesian origin. I'm not sure how important it is to have proper elevation in your projects, but I'd do the following : 1] in CE, create a terrain ( note the limitations there concerning raster sizes in CE ) 2] import the OSM data into CE ( should not be an issue about projection at all ) 3] project the OSM data onto the terrain 4] create rules for your buildings ( main task of course ) 5] export to FBX and load into Unity If you need the buildings also in ArcGIS otherwise, export to MultiPatch (GDB) or kml. OK ? Matt

haha.. amen ! 😉

Hi, yes, currently this is not supported on tablets either. though you can stay informed via upcoming esri conferences and announcements. matt

‎01-24-2014

Hi ! Yes, that is indeed :mad: It's a known issue. As a workaround, I'd recommend to use always well-known projections, such as e.g. UTM, so they are known in any case. Matt

‎01-23-2014

Hi CityEngine does not have such features, CityEngine's just the tool which can help you with creating the buildings. But ArcGIS has strong simulation tools for such cases. Ok ? Matt

‎01-23-2014

Well, there's currently no around this .. 😞 Sorry. And I'm currently really busy, so I have no spare time to help out with this .. Maybe play a bit in CGA and let me know how you progress.. ok ? Matt

‎01-23-2014

Ok.. well, if you need a lot of such precise control, the code may get a bit complicated. But in general, I'd try to never copy rule calls, e.g. like for reporting. e.g. instead of calling the report rule from within every case statement, just call it once in the next rule. What may help is to create so-called generic attributes. That way, you can pass everything down without rule parameters and can work with less case statements. Pumping all geometries and all volumes through the same logic streamlines the code a lot.. A lot of theory.. sorry. 🙂 I'd like to help you out with coding this more properly, but I'm swamped with work right now .. 😞 a bit cooler/more automatted reporting : Note that this automatically accumulates the totals in Vol & GFA too. Reporting --> report("Vol." + myUsageAttribute, geometry.volume) report("GFA." + myUsageAttribute, geometry.area(bottom))

Hi ! You still have an awful amout of code duplicated. I'm sure you can still erase lots of that. Especially in relation to those reports. I know it's difficult to track this down .. This here may help you if you've not seen it already : Also, make absolutely sure you use the Model Hierarchy to track these things down. Check here : http://forums.arcgis.com/threads/44417-CGA-Understanding-the-concept-of-the-scope Let me know how you progress ! Matt

‎01-22-2014

Hi ! You need to distinguish between 2 things : 1] The GUI creates streets and shapes ( I usually call this phase 'shape creation' ). That's done either manually or via Python. 2] CGA starts on a given, existing shape with attribute evaluation and model generation. Phase 2 comes after phase 1. This also means that CGA can NOT alter the state of things that change shapes. Thus, your things need and can be done with Python. Make sense ? Matt
