Hi Brian Lee,
Thank you for your question.
You are right that by default there is no edge info stored for parcels. And if nothing is defined as edge info, all parcel edges fall back to the default orientation "side" and the default adjacency "interior".
The orientation and adjacency values of parcels can be calculated in CityEngine. Please refer to the CityEngine documentation to learn more about the Compute edge attributes tool.
If you want to have EdgeInfo for all parcels of your Urban Model, we suggest calculating the edge attributes of your parcel layer in CityEngine engine first. Afterwards, you can import your parcels into your Urban Model through the Urban Data Manager and define there which source attribute of your parcel layer contains the edge infos that were calculated in CityEngine.
Alternatively, you can also calculate edge info per Plan:
- Create a Plan in Urban
- Load the Plan's content (Zones, Parcels, Overlays) into CityEngine by using the Urban <-> CityEngine interface in CityEngine
- Calculate the edge info with the above-mentioned CityEngine tool
- Sync the Plan's content back to Urban
Please refer to the CityEngine documentation to learn more about the ArcGIS Urban integration in CityEngine.
Hope this helps :-).
Thanks,
Dominik
