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.

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).

Hello @AlexWierzbicki Thanks for your question. To create group reports based on an object attribute "Land_Use", you can concatenate the group name "total" with the string attribute value of "Land_Use". attr Land_Use = "empty"
@StartRule
Generate -->
report("total."+Land_Use, geometry.area/10000) This should yield the desired result:

Hello @MattOlsen Thanks for your question. Your code above looks good. I assume your OBJ files have "zUp". The CityEngine OBJ-exporter writes "yUp" files. The "assetBestSize" search returns the asset with the best fitting size, from the files specified by searchQuery, according to the specified axisSize string. If the lots are bigger than all assets, it is likely that the biggest asset is returned in all cases. To test this, I suggest creating a shape and assigning your CGA-rule. Then, use the transform tools to adjust the size of the shape to the assets. Eventually, an other OBJ-asset will have the best size. If you want to randomize the asset insert on the lot, use assetApproxSize function—ArcGIS CityEngine Resources | Documentation

Hello @rebmamoun Thank you for your question. It is possible to export the properties of parts of a model with the report functionality. The attributed models could then be used in software simulating the microclimate. Further info on reporting can be found here: Tutorial 11: Reporting—ArcGIS CityEngine Resources | Documentation report operation—ArcGIS CityEngine Resources | Documentation

Hello @Krishnendu_MB Thank you for your question. In ArcGIS Urban, the buildings are stored as Spaces. This Spaces can be procedurally generated based on the zoning regulation, building type, and manual parcel overrides. The CityEngine integration with ArcGIS Urban is limited to making changes to such parcel shapes and their parcel attributes: ArcGIS Urban integration—ArcGIS CityEngine Resources | Documentation Please note that CityEngine does not support importing manually edited spaces, buildings from footprints and custom demolish areas: Develop a parcel—ArcGIS Urban | Documentation

Thank you @Bee-am Your use case is to collaborate on a project in your team. I can see that unintentional overwriting of files can be a problem. Can you tell me a bit more about how your team is sharing the projects? Are they saved on a network drive? Do you need a solution for concurrent editing?

Thanks @biaozeng, for providing the reproduction data. The issue is caused by not separating the footprint geometries. Therefore the rule package (rpk) is applied on a single big geometry that fails to fully generate. To fix this, add an additional attribute "primCls" with the value "$PR" (Primitive Number) before assigning the rpk: This will lead to the correct result:

The approach only works for horizontal and planar Shapes like building footprints. The axis of pivot and scope must be aligned. Generally, rectangles can be created with the innerRectangle operation.

Hello @MelanieVT Thank you for the question. I suggest taking an iterative approach using multiple obstacle layers: Obstacle layer—ArcGIS CityEngine Resources | Documentation. Create an obstacle layer for the high-density residential area and grow a dense street network Then grow a separate, more sparse network for the medium-density residential area as an obstacle. Proceed with the low-density residential area accordingly Now combine all three networks in a single layer and do a graph cleanup: Cleanup streets—ArcGIS CityEngine Resources | Documentation To ensure all parts are connected, grow the network together using the recreation area as an obstacle layer. Finally, create a continuous road network by analyzing the graph and adjusting the street widths Analyze graph—ArcGIS CityEngine Resources | Documentation
