Array Code in Inspector CGA examples?

Anonymous User

Could I get access to the ESRI.lib/Urban/* rpk? I see that the urban rule pack in the ESRI library rpk has a ton of array initialization and I would like to "reverse engineer" that so I can see how it is done.

Really, I just want to see code that has been written that makes use of the newish array features in the inspector. I think it could be particularly useful when I do a comp.index edge selection, so examples of that would be tremendous. I have been making between 5-10 attributes for edge selection features, where I think a single array could work. Thanks!

Sorry, we cannot give out the Urban code as it is an essential part of the product ArcGIS Urban.

There is a tutorial about importing data from a CSV file which uses arrays.

Tutorial 21: CSV import—ArcGIS CityEngine Resources | Documentation

This rule that makes legends is another example that uses arrays and CSV files.

Note also that there is the comp function which returns an array. This might be helpful for calculating and storing per-edge attributes. See the edge example in the help doc here:

Hi Brian, the new Resources pages are live ArcGIS CityEngine Resources | Tutorials, Documentation, Videos & More but the 2020.1 download doesn't come out until Oct 29. Be sure to check out 2020.1 highlights of the new features What's new in CityEngine 2020.1—ArcGIS CityEngine Resources | Documentation

Enjoy.

Thanks Cheryl! I will check these out. No problem with Urban Code, I was just looking for array and csv examples, which your new tutorial provided. So is 2020.1 live now? I cannot yet find it in My ESRI. Sorry, I am impatient and excited to try the new version and check out the new tutorial. Thanks again!

While I would still like to see more and better examples of array functionality, my opinion after a little experimentation on comp index selection is that it is better to set multiple attributes for comp functions, rather than an array attribute. In the inspector, I can slide the attribute to see model impacts quicker than I could adjust array numbers.
