i've made to generic model floor based family. family 1 is a custom concrete piece as i'm drawing up a skatepark. The other part is made generic model floor based for lack of better options. This piece, family 2, is a curved metal rail which is partly sunken into the concrete part. However, i'm not sure how to make family 2 remove mass (boolean) from familiy 1. I want to do this partly for keeping track of masses, but also to clean up my section. See the attaced image...

Search the HELP using the term "cuttable" - the answer is there.

from what i can see the cuttable- section you're refering to is only concering wheter or not the object itself is cut in the current view and to what extent it is to be detailed. My objects are cutting just fine in regards to the view, but they are not cutting/intersecting among themselves. Or have I misunderstood?

Sorry ... I did not completely read your question. Did you try join geometry? If that doesn't do what you need, you may have to include a void in the family that cut's the host. Just create a void and set it to cut the host before you finish the void.

Aha, I see.. I had that as an option. What I ideally wanted was for this to happen automatically in my Revit project. The families are thought of as component that will be used in various projects and with different combinations. So if i could keep the geometry clean, and revit would create the voids for me based on what combination i've set up (sometimes the key-hole profile is just a round metal rail, sometimes a standard metal profile etc.) it would be much more intelligent... any ideas?

It is automatic.... you created a floor based family so this can only be used on floors and the profile is what you created in the family.... If you don't want it to cut, then don't place it below the face of the host. BTW - A face based family can be used on any face - floors - walls - ceilings....

Thanks for the reply! As a follow up, i made a facebased version of the object i want to place on the face. However i'm unable to adjust my sweeped objects elevation in reference to the face. The elevation property is greyed out in the project and if i try to adjust its elevation in the family itself i get the error message saying it's unable to create sweep... to clearify: Is there a way to change the elevation of a face based family in the project or how to: move a sweeped object in z axis? (as seen on the attached image) really appreciate the help!

I did a workaround by editing the sweep profile and lowering it to the apropreiate height, but still searching for answers for future reference on my previous questions...

If you want to adjust the height above the face of the host, start your family by placing a workplane somewhere above the face of the host. Build your model around that plane and constrain it to it. Now add a type (or instance) label dimension from the face to this plane. (You will want this plane above the bottom of your objects if you want the objects to embed in the host.)
