Hello, I have a number of walls varying in height and length and I would like to annotate them in a way e.g. “Wall Length 5.20 , Wall Height 8.50” in the plan view. I have tried to locate the center point of elements and prepared the strings list. I am putting the strings as parameter values but I fail to have them put in Category Tags in the model. What is it that I am missing here? I reckon it has to be something to do with the Tag Family and it’s inside parameters but I can’t get this done. ![Wall Text 3d_2020-04-29_04-05-41](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/5/6/56fab11618a0f4fe8296783e63503bf20af88b01.png) ---

If it is something wrong with Tag Family; Should I put the parameter name of WallType to edit Label parameters or Family parameters? ---

You need to use Create Annotation Tag from archi-lab or another tag creation node. ---

I don’t understand the string input. Is this an actual tag family or a generic annotation family? Tags don’t usually work with family parameters. ---

It is the multi-category tag family. So should I create a generic annotation family and try it with that one? ---

Can you explain the string input parameter and show a picture if possible? Are you trying to fill out a parameter in the tag or the element? It should work the same way as your initial graph: tag the element then set the parameter. ---

I was trying to fill out a parameter in the tag but apparently failed to create the family tag right. So, I did it using a generic model and a model text, setting the parameter to the model text. Thank you for your help Nick! ---
