Working with ifc-attributes

artmusicstudio

hello,
i have to dive ibnto bim and ifc-parameters.

i must confess, that i cnnot find the correct parameters in the compo-instance oder definitions in the ruby-api.

so for the start

if i iterate thru comp.-instances in the model,

is there a way for examlple to

-read out a table of all existing assigned (manually in the components in sketchup or imported)

-edit them (for example changing some letters)

and write them again back into attributes?
and eventually generate a new attribute with a new value ?

thanx for helping in advance.

stan

edit:
i found out, that the ifc-attributes are similar like other attributes dictionaries, so i could read them out by

    dictionaries = mycompo.attribute_dictionaries
# Iterates through all dictionaries and prints to screen.
dictionaries.each { |dictionary| puts dictionary.name }
puts ""
attrdict = mycompo.attribute_dictionaries['dynamic_attributes']
attrdict.each_pair { | key, value |
puts "#{key} = #{value}"
}
