Hi Brendan, Thanks for the video it was very helpful, I am actually looking at bigger plot level generation of building based on FAR and ground coverage. With the help of this video I tried to make a rule where I have split the plot into parts based on there input dimension, but I am unable to achieve the FAR value and Ground coverage. Basically I am splitting a bigger parcel by the following code Lot --> split(x) {{~Length : SPLITZ | ~Length : SPLITZ | Road_Width : Road_Color}* | ~Length : SPLITZ } SPLITZ --> split(z) {{~Width : DevelopLot | ~Width : DevelopLot | Road_Width : Road_Color}* | ~Width : DevelopLot } DevelopLot --> offset(-((sqrt(geometry.area)-sqrt(Gcover*(geometry.area)))/2)) Test_2 Test_2 --> comp(f){inside: FootprintReach | border: Lawn_Color}    ////// FootprintReach --> ReachRecursion(MaxFAR * geometry.area) ReachRecursion(restArea) --> case restArea < geometry.area(bottom) : Done. else : extrude(world.y, FloorHeightFunction) VisualizationReach(CurrentFloorIndex) set (CurrentFloorIndex, CurrentFloorIndex +1) comp(f) { top : ReachRecursion(restArea - geometry.area) | all : NIL} VisualizationReach (VolumeType) --> case VolumeType == 1 : Volume("GF") else : Volume("UF") I guess the issue is in my code that I am duplicating my ground area in each plot because of which the building is having same height regardless of FAR and Ground coverage. The intention is to make a rule file like I have seen in the video where you can change your dimension of the plot and also change FAR w.r.t ground coverage and also having a floor variation parameter. ...

Hi Cheryl, Sorry I was offline for few weeks so was not able to reply. Thanks for the details inputs you have provided, it has helped me to achieve my target upto 80%. Currently to achieve this issue I have first divided the plot into smaller pieces using split(x) {50 : split(z){60:Footprint}*}* and then used  Lot --> case p(greenspacePercentage/100😞 report("Area.Greenspace",geometry.area) GreenSpace else: report("Area.BuildUp",geometry.area) BuildingLot which more or less provide me the percentage breakup for the for greenspace, building and openspace.  Thanks for navigating me to the tutorial.  I am still working on making rule for various subdivision of plots like it happens in default Block Parameter. where I can apply my percentage breakup.   ...

Sorry I confused you bit there, I can not use splitArea since my version doesn't  support that function, So I am using split function in both direction to achieve 33% Greenspace (GS), 27% Openspace (OS) and 40% Building (Bu), like the code below split(x) {'.21: split(z) {'.21: OS | '.57: OS |~1: OS} | '.57: split(z) {'.21: Bu | '.57: GS |~1: Bu} | ~1: split(z) {'.21: Bu | '.57: Bu |~1: Bu}} Bu--> shape : split(x) {50 : split(z){60:Footprint}*}* As you see this one option that generates from the above code.  What I am trying to do is randomize between greenspace, openspace and building. Which is like this The above I have achieved using the block parameter using recursive subdivision, but the issue in using this is we cant control the percentage we need for greenspace, openspace and building. One advantage I see is we can control the building footprint area say 3000 sqm and seed function where it control randomness between the plots. Can this be achieved using split function and also using seed function where it control the randomness for plot by retaining the percentage breakup. ... View more

In your case I guess you have to choose "Align graph to terrain". Select all the objects, right click on the viewport and click "Align graph to terrain", set y=0 Cheers Ab ... View more

You can select all the objects and use "align shapes to terrain" option and select y=0 this will bring everything to one level, I hope this helps you. Regards Ab ... View more

Hi Cheryl, Thanks for your kind reply. Since I have CE 2015.2 can I upgrade my version with my current license? Thank you for letting me know about the misinterpretation of stochastic rule, I was using that thinking of randomizing the placement of building, green space and open space. When I use split(x) {'.33: OpenSpace | '.27: color("#FFC500") | '.4 : split(x) {50 : split(z){60:Building}*}*} but this divides in one direction which gives me one option. If we see block division parameter where we can see offset division where we can create courtyard division with openspace in the middle and buildings around it, similarly recursive subdivision we can give randomization of parcels. My intention is creating the similar code where I can give this randomization or courtyard visualization for a parcel which I have in 5ac of plot. I think this function can be made without using block division parameter. I hope this is understandable, Please let me know if there's a way where we can achieve this subdivision function. Thanks Ab.  ... View more

Hi all, While searching in the discussion forum, I found part of my answer of dividing the plot in direction to achieve the floor area for building which is 3000 sqm. split(x) {50 : split(z){60:Extrude_Building}*}*} also the rotation scope can be managed via, rotateScope(0,Rotation,0) but I am unable to randomize the split function, lets say my plot has to be divided in 33% of green cover and 27% of Openspace (which will also include setback from street and distance between the buildings) and rest 40% should be cover by buildings with 3000sqm foot print, and all this should also gives options so that when I regenerate the model I can choose which is better. I tried using the percentage but somehow it is not working Lot --> 35% : split(x) {50 : split(z){60:Extrude_Building}*}* 27% : OpenSpace 33% : Greencover else : Extrude_Building The above code provides just the one of the options but not all together. Can anyone suggest how can I achieve this. Thanks Ab ... View more

Hi David, I am having City Engine V 2015.2 advanced License. I am new to CityEngine so I am following tutorial, I don't know what parameters are needed for the function to work. Please let me know if my version covers everything that is needed. Thanks  Ab ... View more
