Hi

I'm am currently designing a hydraulic manifold with several common cartridge valve cavities. So have decided to create library features of the valve cavities so have started new part created a boss extrude on the front plane to create a cylinder and then created a revolve cut on the right plane inside the cylinder.Then I draged the revolve cut feature to a folder in the design library and created the library feature. Great, too easy . Turns all bad from here!

Opened the manifold part an extrude boss cube and created some circular extrude cuts 0.78mm or 0.031" deep as a spot face to locate the cartridge valve cavity.

Then draged the Library feature to the spot face and it will only snap to the plane the revolve cut the library feature was created on.

can someone please explain or take the attached part with the library feature and show me how to correctly create the feature so circular library cavity aligns with the circular spot face on the manifold part when draged and dropped onto the part.

Thakyou
