Hi @judy. Could you please be more specific on the format you would like to convert into. Yes those labels or annotations can be converted. They are usually represented by points. If you could share some of the data I am sure we could show you how to do that. The result would be points with the text stored as attributes.
Besides the excellent point of gisinnovationsb (FME supports different kinds CAD readers/writers and the solution might be different depending on your output format), the basic way to solve your problem would be to not explode your blocks into entities (this is a setting in ACAD readers).
Normally, each block will be represented as its insertion point containing information on the visibility states.

Thanks jneujens, will try that.

Thanks gisinnovationsb for the reply, I'm trying to convert a dwg file into Esri Geodatabase (ArcSDE Geodb). I will not be able to share sample data as we are working on a client site and it is not possible to get any sample outside.
Thanks,
Did this answer solve your problem? Or do you need more specific information?

If that is the case and you are sure that you have done the things properly, perhaps FME does not support reading that specific attribute value. I am really advising without the data.
Hello @jneujens and @ gisinnovationsb,I was able to get the
text values, thanks for the help. Actually the CAD block included multiple attributes
(example ID, Type, North ...etc. , please have a look at the attached
screenshot), I got the text values without getting the tags and prompt. I
extracted the autocad_attr_def_prompt and autocad_attr_def_tag but always
getting null values, any advice?

To help you with the attributes, I think I need to have a look at your workspace and some sample data!

Hi @ gisinnovationsb , attached is data sample for your reference. Thanksblock-example.dwg
I can't open the file neither in 2016.1 nor 2017.1 can you open it on your side?
