Hello,

I am trying to form a louver on sheet metal part.

when I drag the louver from a design library, it doesn't highlight target face and upon releasing mouse it asks me if I want derived part ?

If I say no, it open the louver form tool in the seprate window and if I say yes, it adds as derived part in feature tree with mating options to position it.

I tried in Help but it has same steps that I drag and drop on targetted face.

what am I missing here ? Plz, help. Attaching snapshot for the message.
