Place multiple family host to multiple floor

I am currently using the FamilyInstance.ByFace node to place host (multiple family) host faces on the bottom or above floors (multiple floors). I enter the coordinates from the processed cad into groups by name, then project it into the floor and the right type of family into it. After reaching the nodes near the end, an error cannot continue. Please see what I have encountered. Thanks.

Mine is much simpler. It places a central node in each space and attaches however many families you want to add. There is an offset built in as well, so you don’t end up with a big pile in one spot.

It is basically a data dump to populate an entire building with items that are found in every space every time, you will have to re-position and re-host the individual families after.
