Detecting Colour values on extruded poly

[curtedmonds]

so, another work around im trying...

Is it possible to extruded a building then extrude the sides,...(now the question) then test if those side extrusions have a color value below itself.

(from a texture map), I don't mean just mapping a color value to the base original shape,I mean any sub shape procedural created.

the purpose of this is to to work around imported shapes not having street information, (ie: i cant use comp(f) { object.street:foo} thus painting the street a color and testing shapes against it would help solve this problem, unless someone knows a way to inject the street info attributes?

tks to any large brains out there

In CGA, you can only map to layers from the initial shape. No intermediate shapes or leaf shapes can map to other layers.

You can use Python for this. Might be pretty complex though. Or you can do something in ArcGIS to the data before using the shapes.
