Hello,
is there no way to delete an imported "shape" with CGA? Within the scene it's extremely simple to single click on a building footprint (object within a shape file imported into the scene) so it's selected and hit the [delete] key on my keyboard. City Engine Help says: "The NIL operation deletes the current shape from the shape tree." But how can I actually use it in a cga file to delete a shape that the rule file is applied to?
