Hello. I’ve got big problem with counting deleted elements in my ruby script. Here is below piece of code I use to count components definition and its instance on scene. is_snapping_point_component_definition is just function which checks if function fulfill condition for being treated as interesting component from my point of view.
So basically I’m searching for all component deifnition and its instances which are still valid and count them.
def self.set_snapping_points_visibility(value)
count = 0
count2 = 0
definitions = Sketchup.active_model.definitions.select { |d| is_snapping_point_component_definition?(d) }
definitions = definitions.uniq
puts 'Component count: ’ + definitions.length.to_s
definitions.each { |d| d.instances.each { |i| count2 += 1 if i.valid? } }
puts 'Entity count: ’ + count2.to_s
end
But very strange behaviour is there. If I add item to empty scene everything is fine. But after deleting instances from scene (even purging everything from scene and leaving blank), numbers are still the same as before deletion. First I told it was because I need to check deleted/valid flag and then I’ve added that check. But that didn’t help. However creating new document restore back numbers to 0.
Any ideas? I just think that I don’t understand how Sketchup is storing instances.
