Hi, the @Range() and @Group() annotations belong to the attribute. the comp(f) code fragment is at the complete wrong place there. ok ? m.

with .obj assets, the .mtl file is also needed, because it stores the actual texture reference per material in your asset. so if you only copy the .obj file, the texture cannot be displayed, even if it's sitting there. => check out the .mtl files. note that you can preview .obj assets in the Navigator within CityEngine ( check Help ). If the texture is shown there, the .mtl is ok. If it shows an 'unknown texture' standin texture, most probably the texture paths in the .mtl are slightly wrong. (open a .mtl in a text editor to edit paths ) Ok ? m.

Hi, Improving the roof() operations are a high priority on our wishlist - currently, not all is possible. This shall be improved in future ! I'd recommend : manual way: - for now, model special roof forms with the 'Polygonal Shape Creation' tool (tutorial 14) procedural way: - check the additional orientation flag in the roof CGA documentation - case 5 : add a shapeL() on the rectangle first on the footprint Ok so far ? m.

Hi, Of course this is also a valid thing to do, though as you notice, when the graph segments are drawn with the red dotted line, it's shapes can not be created properly. This may sometimes give you a few issues. Though in the end, using the 'Dynamic City Layouts' system is just the process of creating shapes, for later use in CGA. If the shapes you create give a valid topology for your work in CGA, your goal is reached. So yes, go ahead and also use that trick ! sure ! Matt

Hi ! It's easier to work with an asset in this specific form. Not everything needs to be modeled procedurally in CityEngine. Check out tutorial 7 (video & link to actual tutorial files): http://video.arcgis.com/watch/1775/tutorial-7-facade-modeling It's best that such assets are modeled with the +Z axis being 'in front'. Use e.g. SketchUp or Maya or Max to model such assets. Let me know if you need more details ! Matt

CityEngine 2013 will have proxy settings. In CE 2012, you'll need to download them manually from here : http://resources.arcgis.com/en/communities/city-engine/01w90000000r000000.htm#s=0&n=30&d=1&md=cte-ce-version:10_cte-resource-type:0000001000 Matt

Hi, You currently need a street on each side. That's the way it was designed, mostly to keep things easy. The 'Dynamic City Layouts' system is not an extremely realistic system, but one which allows you to use easily and fast. If you need very detailed and precise subdivision patterns, you may want to still draw them manually. Ok ? 🙂 Matt

Hi Caroline, RPKs can currently only be created with CityEngine 2013. Now, since that's not yet out, that's an impossible thing to do currently for 10.2 users. Additionally, the first hotfix will need to be run to eliminate some more issues. Though also it's not yet final, when this hotfix will be released. So it'll take some more time. Sorry for the bad news. Send me a mail for more Esri-Distributor-specific info. 🙂 Ok ? Matt

Hi, yep, the answer is no, but what you could try is the following : Just subdivide the block with an other street and set that street's width and sidewalk widths to 0. you'll get a red dashed line since the street shapes of this segment cannot be created. But this'll give you more control. Of course, each of those blocks could have mapped subdivision params too. ok ? 😮

Hi, if it's a rotation around world.y, then I'd propose you just rotate the whole scene (manually or via script). rotating the exported model around x or z is most probably impossible. There' you better postprocess the resulting geometry file, maybe in an other 3d app. let me know .. M.

Hi, The Facade Wizard creates CGA code which is 'hardcoded' to work automatically only on vertical ( world orientation yUp, direction of gravity ) shapes properly by default. Note that the Facade Wizard produces rules which should only be assigned to exactly rectangular shapes. If you look at any rule created that way, you'll note a thing: > any split done is in scope.sx or scope.sy If you watch this video closely : http://forums.arcgis.com/threads/44417-CGA-Understanding-the-concept-of-the-scope you'll learn that after a comp(f), the scope is automatically aligned 'zUp'. Means after an initial first extrusion of a footprint, after this Mass'es comp(f){side.. }, you'll get Facade shapes with a zUp scope, scope.sz being 0 since the polygon is flat. Thus also logically follows that any split must be done in x and y direction. Now in your case, where you do e.g. a comp(f) to get the sloped or flat roof shape, theoretically all splits produced are already ok and usable, since those splits are always done RELATIVE to the scope, no matter what the orientation in the world is. So in theory, you should get this working very fast. I did never try this yet, but it's worth a try. Let me know .. m.

Hi, check this post about the '-Dagol' switch : http://forums.arcgis.com/threads/72636-Esri-CityEngine-2012.1-Software-Authorization-Patch-available?p=286835&viewfull=1#post286835 On startup, CityEngine 2012 waits for the connection of ArcGIS Online ( AGOL ). The timeout of that server is set a bit high, so that usually causes a couple minutes of delay. Setting the switch will abort the search for a possible AGOL connection, thus it'll start faster. Though of course that way, you cut off the possibility to share WebScenes directly on AGOL. Lemme know if it works. Matt

Hi, If ever you want to place rules, post them here : http://resources.arcgis.com/en/communities/city-engine/01w90000000r000000.htm#s=0&n=30&d=1&md=g-contributor:010_cte-ce-version:10_cte-resource-type:0000000001 I assume you're talking about interaction between static shapes and the 'Dynamic City Layouts' system ( Streets, Blocks, Lots ) ? Those do not interact, that'd be a very hard thing to implement. Maybe describe what you'd need to do, then I may know an other way to do this. Let me know.. Matt

Hmm. It could be that your viewer software thingy interprets coordinates differently, e.g. like the yUp / zUp coordinate system differences between different 3d packages. You can track this down easily with just a colored cube or so, to check the final translation in your viewer. Good luck ! m.

Hi, Playing with it is the best thing. Not everything is possible of course, but if you need specific forms, post an image of them and I can tell you precisely if and how they can be built in CGA. I just need an input image to check. Matt
