Extruding polygons using attribute

aogino — Fri, 31 May 2024 11:23:35 GMT

What is the right .cga rule to apply to a shapefile in order to extrude the polygons in it to a height using an attribute of the shapefile ?

Currently using this one that I found on the net :

version "2023.1"

attr hauteur = 10 // Default value in case the attribute is missing

Lot -->
extrude(hauteur) // Extrude the shape to the height specified by the "hauteur" attribute

@StartRule
Building --> Lot

But it isn't working. Any kind of help would be appreciated !

Hello @aogino

Your CGA code compiles without error. When applying it to a shape, the resulting model is the shape extruded by 10m.

Your attribute title "hauteur" needs to match (case-sensitive) to the object's attribute for this to happen automatically. Otherwise you need to simply "Connect to Attribute" and everything should work as intended.
