Automation Model Creation in CityEngine

I now have a set of data (e.g. road width, road type, etc.) saved in the local disk. Is there any possibility for me to use this data in CityEngine based on CGA rule (or Python maybe?) to automatically generate a model (or models) in the 3D viewer? cityengine 2019 cityengine 2019.1 cityengine 2018 cityengine 2017

After importing your data into CityEngine (Import data overview—Help | Documentation), you can apply a cga rule to your shapes. There are two rules for streets that come with CityEngine and can be found in ESRI.lib/rules/Streets. David Wasserman has a Complete Street rule that you can use (Complete Street Rule Update). Or, you can write your…

Dear Thomas Fuchs, is there any update in Revit support in City Engine, since ArcGIS PRO can import it natively? Thank you. Regards, Vladimir

Changing report names in Python tutorial 12

Hi, I’m stuck in the CE Python stuff. I need to create a semi colon separated list in a text file summed by the start shape. So exactly like in Tutorial 12, I’m not getting any errors anymore on export, but as soon as I replace the names from the tutorial 12 to my own names in the reports, it’s not writing the text file any more. As soon as I… (Show more Show less)

In the code above, there is a mistake in the output filepath definition. ce.toFSPath() needs a valid folder name. I think you meant: file = ce.toFSPath("assets")+"/instanceMapHaps.txt" Once that is changed, your script seems to work. As for the reported values, every shape in the scene reports its own value, and this is what is written to the…

Color RGB on a texture

Hi, is it possible you read a pictures combined RGB values. I’m trying to figure out a way to determine how light or dark a texture is, and I was wondering if I could do something similar like when you read the RGB values on for ex. A rooftop from the map layer? Thanks.

I don't understand exactly what you want, but I can say that it is not possible to access the RGB values in a texture image or the average brightness of the image from within CGA. Nicolai's answer is the only way I can think of to access the RGB values in images.

Finding the lowest Point

Hello everyone, i have the following problem in my Cityengine project. Because of the hilly landscape I built my buildings on flat tops. But then the doors of the buildings are not at the lowest point. As already suggested in another post, I have therefore created stairs. However, I would still be interested to know if it would be possible… (Show more Show less)

Unfortunately, there isn’t a good way to do this. I don’t think it’s possible. This is because it is currently not possible to access the terrain elevation from within CGA. Nevertheless, here are some suboptimal ideas. Idea 1 One idea for a workaround is to do something like what this post does and create shapes that follow the terrain and…

Hi Cheryl, Thanks for your input on this thread already! I've followed what I think is the approach outlined above, looking to embed multiple report values into Object Attributes. I'm not having any success - first time wrangling Python. My scripts look like this at present, both made via the Python template modules - are you able to help? Much…

Are you using 2019.0 or 2019.1? What is the rule file and start rule assigned to a building? Does this rule exist in your workspace? Click on a building. In the Inspector, is the attribute Representation set to "realistic with facade textures"? If it is set to "solid color", which is the default, then the buildings will not have a texture…

When getting Map Data, does it have to be a rectangular boundary?

I want to collect data in a specific polygon shape, but it seems I can only drag my mouse and have a rectangular study area. Does anyone know how to change this?

Yes, so when I am getting map data for a new scene, I can only capture the extent with a rectangular clip. I added a screenshot below as an example. Is it possible to change this shape? Say I wanted a triangular study area, how can this be done?
