I am working on a rule where a land lot goes through a series of checks, and can only continue to the next part of the rule once all check conditions are met.   I need to check the following: - the area of the shape needs to be larger than 100 - the length of the first edge needs to be greater than 25   I’ve got my rule set up so as follows:    attr AreaPass = false attr LinePass = false Shape -->                 case geometry.area >= 1000:                                 set(AreaPass, true)                                 print(geometry.area + " is area")                                 print(AreaPass + " is area")                                 LineCheck                 else:                                 color(1,0,0) #color the shape to show an error LineCheck -->                 comp(e) {0: FrontLine} FrontLine -->                 case scope.sx >= 25:                                 set(LinePass, true)                                 print (scope.sx + " is scope.sx")                                 print (LinePass + " is scope.sx")                                 TestsHavePassed                 else:                                 color(1,0,0) ##fail TestsHavePassed -->                 case LinePass == true && AreaPass == true:                                 print ("pass")                                 color(0,1,0) #color the LOT green to show that it passed                                 extrude(10) #Extrude the LOT shape by x meters to show that it passed                 else:                                 color(1,0,0) ##fail                                 print ("fail")‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍   The issue is that I can't extrude the original lot face by x meters because by this point I've split the object and only have an edge left to work with. Is there any way to run a geometry area test AND an edge test, and if they both satisfy their conditions, then an operation will continue on the original input shape? ... View more

We are currently working on a large CityEngine project that requires multiple people working on the same project at the same time. It is also very resource heavy due to complex building forms and detailed texturing. We are currently dealing with some important questions relating to large project workflows: - How do we allow multiple people to work on different layers or aspects of the same project? We have considered a git repository, but since layers are stored within the local project, and the cej file is binary, there is no way that we can easily merge and manage changes/conflicts between different users' work. - Is there a way to allow for external data sources and layers to be brought into a scene and remain as referenced sources and not locally stored files? - Have any of you worked on projects requiring multiple CE users/editors/designers, and if so, how have you dealt with similar issues? Thanks ... View more

We are trying to create a workflow for importing BIM models into CityEngine. Currently, the only way that we have successfully imported a model is by converting the BIM to fbx and importing as a static, solid object. While this preserves geometries, all attributes and textures on the BIM model are removed, and we can't remap the textures onto the model for visualization. We are now trying the export to IFC, and then create a workflow that preserves at least some of the attribute data by converting the model into a geodatabase with multi-patch data. This looks promising, but we've been running into multiple issues along the way that prevent us from creating a model that actually reads and visualizes properly. I'd be interested to hear about other user's experiences with BIM --> CE workflows, and if anybody has successfully been able to import a BIM-created model (Revit) into CE or a geodatabase. ...

I'm trying to place a height map/terrain image (it's an obscure shape with transparency) in CityEngine but whenever I add it I end up with strange height extrusions around the border of the image. I've tried to export the image as cleanly as possible without anti-aliasing/compression, etc. and I've saved it as a PNG-32 with transparency, but whatever I do ends up with the following result: Is there any way to tell CityEngine to ignore or clip out the messy border on my terrain? Or is there another way to prep the file so that this issue doesn't occur? Thanks ... View more
