Hi all I have a question, is it possible to have an attribute where the start value changes according to the shape which the rule file is added to. A simple task could be that the attribute should always be half of the area of the shape, so on one shape with the size 2000 sqm, the start value would be 1000, on an  8000 sqm shape the start value would be 4000.   kind regards  Kristian ...

Hello All. I'm currently working on a way to create a CGA rule file which can generate many different buildings within a short period of time. The goal is to create a rulefile which lets the designer investigate multiple designs without having to redraw his/her project every time. I'm working with the assumption that a design of a building plan consists of three parts, the distributions of the building footprints (bldgFootprints), the envelope (bldgEnvelope) and a facade (bldgFacade).  The goal is to have a main cga rule file, which link to a rule file that draws the bldgFootprints. This file then link to a file which draw the bldgEnvelope, and finally, the bldgEnvelope links to a cga file which draw the bldgFacade.  To avoid having to write all of the different "types" of building footprints in one rule file, I would like the bldgFootprint to link to other rule files, and by using a drop-down menu choose between them. Se diagram below. By using this structure, it would be possible to write a new CGA file for a specific building footprint, and then add that to the overall structure simply by naming the instances within sub-rule file the right names. It would also eliminate the need for writing one very long cga file which can generate all possible building footprints. By using this structure it would be possible to make the "Database" bigger and bigger over time by adding more and more bldgFootprints0X to the project. So the first question, does this seems as a relevant way to do it, it will end up with a very very big amount of rule files and some of them will maybe have the ability to do the exact same thing but on the other hand it allows the designer to create an individual script and add it to the overall structure.  The next question is, I simply can't get it to work, I have managed to link the main file with the bldgFootprint, link that to bldgFootprint0X, link those to bldgEnvelope, but the attributes which is located in bldgEnvelope is not visible in the inspector. It looks like it is only possibly to have three layers of linked files visible in the inspector, so my "main" can link to "bldgFootprint" which can link to "bldgFootprint0X" and all the attributes show up, but when the  "bldgFootprint0X" links to "bldgEnvelope" the attributes for envelope does not show up..  I'm looking for all the help and thoughts I can get on the subject, does any of you have relevant experiences with this type of project, can you see a more simple path through. Am I on the right track or is it just stupid? If anybody has an interest in the project and which to follow it more, you are welcome to send a message to me.  ... View more

Hey all I'm having some problems when trying to add a dirtmap to a surface. I want to be able to control the opacity of the dirtmap in the CGA rule file. This is the code so far, the dirt map shows up along with the Grass texture, it is just to dominating.  BuildingArea -->                setupProjection(0, scope.xz, 2.25, 1.5, 1)             //ColorMap                texture(Grass_Tex)                projectUV(0)                setupProjection(1, scope.xz, 2.25, 1.5, 1)             // BumpMap                set(material.bumpmap, Grass_BumpMap)                projectUV(0)                setupProjection(2, scope.xz, '1, '1)                      // DirtMap                set(material.dirtmap, Grass_Grunge)                projectUV(2) I have tried adding the set(material.opacity,0.5) but that makes all the materials transparent, hope one of you have the answer, and another question, I'm trying to add a bumpmap, but the bump is not visible in the scene, does any information lack in rulefile?  ...

I'm a 99% noob when it comes to CityEngine and the whole programming world, but it looks to me as there is the possibility to use python scripts within CityEngine, which have made me curious, why would you do that?. I have encourtered some problems when writing cga rule files, one of them is that I want to split a shape in two, and then extrude number 1 and split number two into two new "shapes". one part of the secound split will then be extruded so it allways has the same volume as extrusion one, see picture. But this i have not been able to do as fare as i understand it it is becouse it calculates volume one in one branche of the tree and then it is not able to use the data in another branch, is this something you would use python to or what? I now that for this particular exmaple there is some matematiks that can solve the problem, i think what i'm looking for is a way to store some data in an attribute and then use it again but in another branch of the tree.  Another question is I want to import a shapefiles into cityengine, which countain some building footprints, I then want to draw a shape under an amount of building footprints, and then see if a footprint is on top of the shape and if it is then calculate the sqm which is not covered by the footprint.  thise a basically the tasks at hand and i quess the question is, is this something you do with python and what task can python do in cityengine?. Would it improve my skills in cityengine to understand python?  Sorry for the long post ... View more

Hello I'm trying to create a CityEngine project where I want to add a facade to a building. I have created the "Facade.cga" rulefile in a project called "Urb-Day" and now I want to use the same "Facade.cga" rule in another project called "stormwater". I have tried to use the: import F_Facade: "Facade.cga" in the "Stormwater" project, and it works if the "Facade.cga" rulefile is located in the project "stormwater", but I would prefer that "Facade.cga" could be accessed when it is still placed in the "Urb-Day" project.   I think it is just the path to the facade.cga rulefile that is wrong, any suggestions?  ...

I'm looking for a way to download CityEngine 2015 for mac, i can only seem to find the 2016 version. I'm working at my school which have a 2015 license but not the 2016 version, it is therefore important that I find the 2015 version, hope somebody knows where I can locate it.  kind regards  Kristian ...

Hello, I'm new to city engine and is trying to write a cga rule file which will import one of 14 sketchup models (parking towers) onto a lot. I have imported  the models into the asset folder as OBJ files and then use this piece of code Street -->       i(listRandom(fileSearch("Towers/Tower_*.obj")))       s(8.5,12.17,5.59)       rotate(abs, world, 0, 90, 0)       center(xz) #ParkingTower which works, now comes the problem, when I add the rulefile to more that one piece of "shape" and update Seed it chooses the same model at all the shapes which are not what I wanted, I wanted 14 shapes ~ 14 different towers.  I can update each segment of the road, which will give me a new building on that segment, but if I update it 3 times and then update another segment 3 times it will generate the same building, so it seems that it is not random at all   Does anybody have any advice on how I can make it chose a truly random obj? ...
