Was the answer to this question ever found? Looking at the ESRI EULA I can't see anything prohibiting commercial use other than the documentation, tutorials etc. but then my legal parlance isn't particularly good.

UPDATE I've figured out why the shapes built in CityEngine weren't subdividing, the normals were facing the wrong way. One issue once they're subdivided though...they all have the same seed meaning any randomness is removed. I'm getting round this by setting the seedian based on the area of the subdivided shape but is there a more elegant way of doing this? I still haven't figured out what the problem is with the shapefile shapes. Maybe too many vertices?

Is it possible to import shapefile polygons and use them as blocks which can then be subdivided into lots? I've tried using the Shapes > Subdivide... menu option but it just makes the shape dissapear. I've tried the same on a shape built within CityEngine itself and this doesn't seem to subdivide it at all. As far as I can tell from the help file I'm doing it as I should be, but am I missing something?

Is it possible to use a landuse map to set various block subdivision parameters? I have different landuse types in my city (e.g. residential, highrise, industrial) defined in a texture map but the block parameters for each landuse type need to be different. For example, the residential blocks need to be subdivided into smaller lots than the industrial lots. I'd like to use the landuse map to define how to subdivide the blocks rather than having to select them manually in CityEngine if possible. Thanks

Superb stuff Matthais, that works a treat. My city is starting to look pretty good now. Thanks for all your help.

Yet another answer! Thanks Matthais. If I can ask one more question please... I have created a number of buildings in individual cga files. Is there a way to use a stochastic rule to place buildings from within seperate cga files? I've found the import command but I'm not clear on how to apply it. I'd like to do something like this: [ATTACH=CONFIG]11663[/ATTACH]

Thanks again Matthais. It's obvious when you point it out. I've even been using it when texturing polygons. One last question...Is there any way you can set a variable attribute that you can update later in the rule file? e.g. attr lotWidth = 0 attr lotLength = 0 attr height = 5 Lot --> lotWidth = scope.sx lotLength = scope.sz i("builtin:cube") s(lotWidth/2,height,lotLength/3) This would make code more readable and make lotWidth and LotLength available to other shapes later on in the rule file.

Thanks for your reply Matthias. As I'll have to use a shapeL command I have a follow on question - is there any way of querying the lot width? I'd like to create an L-shape with relative sizes for the frontWidth and leftWidth but the CGA requires absolute values. If I know the lot width then I can calculate the absolute values required to give me the relative proportions. I've done this on other occasions by starting with the built-in cube with a height of 1 and getting the area of the front face which equates to the width of the lot. I can't do this if I'm using a shapeL. Thanks

Hi Matthias I was preparing some data to send you but decided to use a jpg with a prj file rather than a geotiff so that the data size was reduced. I did a test import just to make sure the error was reproduced and it worked! I guess I'll use that method instead. Easy really. Thanks Paul

Hi I'm attempting to use CityEngine 2011 to create a model of Singapore. I have a satellite image of the downtown area of Singapore along with a shapefile containing the road networks. Both are in WGS84 UTM zone 48N projection and when viewed in ArcMap they correlate perfectly. However, when I import them into CityEngine they end up seperated by about 400km and 90 degrees rotation. I can use the map offset to bring the map layer into the same area as the shapefile road network but can do anything about the rotation. I guess I therefore have 2 questions: 1. Why don't the two sets of data correlate correctly in CityEngine? 2. Is there any way I can rotate the map layer so I can at least get the image and the road network data lined up? Thanks.

I have come across all three of those articles, but all of them are dealing with a manually entered linear distance (which works exactly as shown in your first link) rather than setting the value from a field in the shapefile itself. As an aside, I can't even find the buffer wizard that's used in the 3rd article you linked.

I have a geographic shapefile that contains a number of points worldwide that I need to buffer by various radii to find areas at which they overlap. If I use the buffer tool and manually enter the buffer distance (in feet) the radii draw as I'd expect in the geographic data frame (the resulting radii look like ellipses that are more stretched the further you get away from the equator). If I read a field in the shapefile that specifies the radius around each individual point (in feet) and use this as the buffer distance ArcMap converts this figure to decimal degrees (all of which are the same regardless of how close they are to the equator) and thus displays them as a true circle. Is there any way to get ArcMap to read the radius field from the shapefile and buffer the points in feet rather than tryin to convert to degrees? I've tried reprojecting the shapefile but I only really get acceptable results in one small area of the world, rather than worldwide. Thanks for any help you can give.
