Hi all,
I am trying to get the location of “Structural rebar tag & Multi rebar annotation” in single shot. I can select “Structural Rebar Tag” by easy picking if i pick the “Multi rebar Annotation” i can’t get the location like “Structural Rebar Tag”. So i need to retrieve the "“Structural Rebar Tag” type from “Multi rebar Annotation”. See my graph below.
We can’t help you if you don’t also share the python code that’s getting the annotation location. If it’s the code from your previous post (which would be nice if you included a link to) then I think it was already mentioned that it wouldn’t work for non-tag elements. You need a different method for dealing with annotations. It also looks like you’re running your code on the category instead of the element.
Yea, @Nick_Boyts so i am just trying to select the Structural Rebar Tag from Multi rebar annotations. Then this python code will works. The problem is i can’t select Structural Rebar tag from Multi rebar annotation by using drag option. But i can pick it easily. My aim is selecting the Tag by using Drag. I have attached my current graph. Thank you for your response.

Thank you! I am new to this forum. I’ve done as you instructed now.
I’m having a hard time following but it sounds like you want to be able to box-select your Multi-Rebar Annotations and have that also return the embedded Structural Rebar Tag. Is that correct?
Take a look at the MultiReferenceAnnotation class. You can get the tag using TagId.

Yes @Nick_Boyts you are absolutely right. This is my clear cut intention.
I follow your suggestion and will post the changes. Thank you!
