FileGDB and Walls

NickCollier — Mon, 09 Jun 2014 18:32:36 GMT

Is it possible to determine which geometry in an exported FileGDG corresponds to the walls and roof? For example, if we have a cga with this:

comp(f) {bottom: report("floorArea", geometry.area) } 
comp(f) { side : Walls(floorArea)}
comp(f) { top : Roof(floorArea) }

I'd like to be able to find the polygons within the Multipolygon / Multipatch that represent a building's walls. Is this possible?

thanks,

Nick

Maybe try different materials.

The other way - which we are reimplementing currently and worked in 2012, but had to remove temporarily due to time constraints - would be to use attribution per created polygon.

But as said, that's not in CE 2014.0 and shall be included again in 2014.1 most probably !

How many 'things' do you need to distinguish ? Maybe I have other inputs.

Thanks for the reply. The context for this is that we have another application that is used to calculate various properties based on a wall's geometry. With that in mind, we only need to be able to tag the geometry that is passed to the Walls function in my original message as belonging to Walls. Being able to do that for the "Roof" geometry would be good too, although right now we are more concerned about the walls.

thanks,
