Hello @richiedlon  Thanks for the question. I hope to help you with your interesting project. You can analyze the roof shapes with the geometry functions—ArcGIS CityEngine Resources | Documentation  Use geometry.area() first, then calculate an efficiency factor from geometry.angle(azimuth) and geometry.angle(maxSlope). These values can then be reported: report operation—ArcGIS CityEngine Resources | Documentation ... View more

Hello @biaozeng  Thanks for your question. To export metadata like the attributes, please ensure Mesh Merging is set to either Per Initial Shape or Per Initial Shape by Material. For more information please consult the CityEngine Help on Export DATASMITH (Unreal and Twinmotion)—ArcGIS CityEngine Resources | Documentation ... View more

Thanks for verifying this. With the connection editor, you mapped the Rule Attribute "Eave_Ht" to an Object Attribute named "EaveHeight". This created the following entry in the Layer Attributes of the "Shapes Sample" layer:   attr Eave_Ht = getFloatObjectAttr("EaveHeight")   All Object Attributes of objects in the source layer at the location are getting sampled. In your case the value of the object in the center is returned. The behavior is expected.  To make a direct connection between a Rule Attribute and an Object Attribute, the names must match. Either add an extra (optionally hidden) attribute to your rule   @Hidden attr EaveHeight = 50 attr Eave_Ht = EaveHeight   or edit the name of the object attribute Inspector—ArcGIS CityEngine Resources | Documentation ...

Hello @richiedlon  Thank you for your question.  Looking at your screenshots, it seems like you connected the object attribute "Height of the Eave" with your rule attribute "Eave_Ht" via a layer attribute. Have you checked what the values in the Object Attributes section of the Inspector are? Maybe the difference is showing there as well?  Inspector—ArcGIS CityEngine Resources | Documentation ...

Hello @Bee-am  Please excuse the late response. I now figured out what is happening: The current version of the Complete Streets Rule does not support bridge occlusion. The overlap/ occlusion queries can cause a rule to generate slowly. The occlusion check on bridge piers was considered an edge case that is not important enough to justify the performance hit. Therefore it was removed in 2018.  If you want to add it back in, edit Complete_Street.cga and replace the "PierCheck" rule with the formerly used code:   PierCheck --> case (Bridge_Display == "On, Show All Piers"): # Occlusion test is disabled, by "On, Show All piers". PierShow case (Bridge_Display == "On, Flag Occlusions"): case overlaps(inter): # This pier hits another model. print("Occlusion true: Bridge pier overlaps another model!") # Flag the pier in red. This is a debugging mode for the piers. color(1,0,0) PierShow else: # No occlusion so show the pier. print("Occlusion false.") PierShow else: # Use standard occlusion method. case overlaps(inter): # Omit piers due to positive occlusion check. # This means the pier would hit a street or other model. NIL else: # No occlusion so show the pier. PierShow     ... View more

Hello @MCh  thanks for bringing this up. SLPKs have a level of detail LoD structure to dynamically adjust the detail depending on the viewing distance. It indeed looks like the untextured faces (with only vertex color) are not shown. For further analysis, would you be able to share the scene layer you created? ... View more

Dear @mohamadhani ,  Thanks for utilizing the CityEngine community forum for support. The forum is indeed a valuable resource for sharing knowledge and experiences with other users and the product team.  However, I would like to recommend that you also consider using the official Esri support. This means they have in-depth knowledge and can provide you with accurate, detailed, and comprehensive solutions tailored to your specific needs.  You can access Esri's official support at Esri Support Services.  Best regards, Thomas F ...

Hello @mohamadhani  Thank you for your question. Procedural modeling with CityEngine allows you to use premodeled 3D buildings. To find the best fit for any given Parcel geometry, use assetBestSize function—ArcGIS CityEngine Resources | Documentation or one of the related asset utility functions. ... View more

Hello @Farhan  Thanks for your question. Your robot looks like a fun education project. To me, it looks like you are returning a floatArray from the distanceMove(n) function. However, the r operation—ArcGIS CityEngine Resources | Documentation needs a float input.  I suggest, that you adjust your function in a way that you derive the leg angle from the Robot_Move value.  All the best for your project! ...

Hello @ChziLi  Thanks for your question. Unfortunately, there is no way to set the curb radius individually. You need to model the street as a detached turn lane (like the one on the left side of the crossing picture).  ... View more
