Are you trying to add an attribute for your own use, or for a Dynamic Component? They both use the attribute dictionary properties of objects, though the latter requires specific dictionaries and formats. ---

Check that your selected entity is non-false (ie, not nil) and actually has the proper dictionary, before trying to get an attribute. Beware of using attribute\_dictionaries['dynamic\_attributes'] because it can return nil if the object’s [Sketchup::AttributeDictionaries](https://ruby.sketchup.com/Sketchup/AttributeDictionaries.html) collection is empty.

> [@bikalbaral13](#): > > when going to model component attributes Can you please explain it how and what are you checking? when you use: ```auto comp=group_brickbats.to_component() ``` …the `comp` variable is a [componentInstance](https://ruby.sketchup.com/Sketchup/ComponentInstance.html). Therefore you set the attributes of that instance. Are you checking the instance or its definition ? ---

Setting an attribute does not mean that it will be a Dynamic Component. [Dynamic Components](https://extensions.sketchup.com/extension/7d49b82a-1e6a-40ae-ab88-82fba11c4891/dynamic-components) is a “similar” extension than the other user created one. It is using its special `dynamic_attributes`. So unless you set that you will not see in the Dynamic Components extension user interface. Dealing with Dynamic Components is something different…Please check again my first post in this topic. PS: Since the Dynamic Components code is not public you have to know (examine) about its attributes before you can deal with them. ---
