need input on multiple segment angularity

[mycan]

Please advise if this is allowed by ASME Y14.5-2009

there are dowel pins pressed into the holes on datum surface A and on datum surface D

It's OK to have different angularity feature control frames (FCF), each referencing a different datum.
However, if there are different holes on the A side and then D side, I wouldn't cluster the FCFs like that because it means that the one hole being pointed to (datum feature B) must be checked to both A and D.

The intent is a single hole for Datum B and a single hole For Datum C. Thanks for the response. Would like to hear more responses.

I'm still learning GD&T, so I am going through these threads to learn new stuff and applicatoins.

I believe your intent is to have two holes perpendicular to datum feature D, and one hole perpendicular to datum feature A.

Actually, why isn't a perpendicularity control used?
