This is neat! Should the XY scope increase as well? ... View more

I also would support this.  ... View more

I have found breaking the file up into batches can help, but ultimately a CE scene can run into extent limitations depending on the scale of the region or city. A county might be too large for a single scene and it might warrant processing elsewhere.  When I run into large scene problems, it helps to either break the region up into districts with script based imports and rule applications or identify whether similar visualizations can be done in Pro with procedural symbols (RPK based visualizations). ...

Sorry for the very long delay. I think much of the issues encountered could be addressed by clever array management. I do see the issue you are running into though for each land use. This seems like something that could be debugged if you attached a CGA snippet with the relevant parameters included.  ... View more

This is generally my experience with working with close up intersection nodes as well. Often the problem can be adjusted for by buffering draw lines in some GIS/CAD platform before import to see where those problem areas will likely occur before hand. It can often be accommodated by optimizing the data for import.  ... View more

The issues I have been running into are similar. For me the second I try to install Seaborn into a clone, Jupyter locks up something fierce. This is an issue for 2.9 for me.  ... View more

CityEngine does not innately support this type of relationship, but there are ways to use the Jython API so that such relationships can be acted on.  https://doc.arcgis.com/en/cityengine/latest/python/commands-by-category.htm ... View more

Brian is correct. I do think though you can strategically tag generated materials for intake into those rendering systems/game engines in CityEngine. Material replacement is something that software like TwinMotion makes really easy if you can search by tag.   ... View more

I think I would need to see the text code to insert (there are various ways to do that now).  The first thing I would try to do this would be to do a component split on of the vertical edge of the building, and insert text relative to that split. The tricky part would be how well that works when you don't have straight edges between floors.  ... View more

It is incredibly difficult to send information up the leaf hierarchy created by CGA rules. One way to approach this is precompute elements based on aspects of the start geometry, but for what you are trying that is not possible. I think an operation that might help is resetGeometry based on some conditional, but it might not function exactly as desired.  https://doc.arcgis.com/en/cityengine/latest/cga/cga-reset-geometry-operation.htm ...

It is incredible how much of rule design is just filename management.  ... View more

I wish there was a better solution than this, but this seems to do the trick! Good suggestion Brian.  ... View more

Unfortunately, this is generally in the control of native CE street shapes rather than the CGA programmer. I put a lot of work into setting up street set back parameters in the complete street rule given this issue. You might have more luck actually setting back some amount and having a perpendicular  transition to a pedestrian area.  If you do find a solution, this is what generally prevents me from creating shared streets in the complete street rule.  ...

Brian hit the nail on the head with my concerns with scenarios. For this reason I typically create separate layers for street networks for each scenario. You can see this in the demonstration animation provided here.  That said I understand, Streets generally need reworking in CE, and it has been on the to do list for a long time.  Scenarios generally perform well for demos and switch between views of a large number of complex layers, they might not need to do more than that. Their export functionality respects key aspects of interest for presentation and the creation of final deliverables.  ... View more

I see the confusion. There is a distinction between CGA & Python in CityEngine. CityEngine I think still uses the Jython API for workflow automation and set up. You have the right idea here. The issue you are having is you need to apply a rule written in CGA to build geometries from lots. I recommend looking at sample rules for this in the tutorials.  This script contains an example used to create different street combinations based on provided attributes as an example. It is based on attributes of the Complete Street Rule.   ... View more
