Revit Arch. 2008 I am trying to create a sink as a face-based family that can be dropped into the project onto a countertop. I am having trouble getting the void that cuts the sink opening to cut after it is loaded into the project. I don't understand what is happening because the void cuts a hole in the countertop in the family editor. Also, I am able to nest this sink into another family and it [I]does[/I]cut the hole in that counter as well. Please if anyone has any suggestions let me know! Thanks,Rafe Redmond

Cant solve, but can help.... I had/have the same issue. If I made the sink with a generic model-face based I can then change the family type to a plumbing fixture. When I place it in the project i can host it on a countertop or a wall or whatever. What I noticed was that it will cut the wall and the floor, but not the countertop. I think it can cut through system based families and not created families..... What do you think?

I have only seen sink cutouts in the countertop family. Face based families are just for the face and and I don't think anything in them will cut a host.

chanus, Are you sure? I have a face based family with a void and it will not cut walls and you can not use join geometry with it.

It looks like the countertop family has the opening instead of the sink family. I need to put 3 sinks in one countertop and the openings need to be circular. It would be much easier if the sink had the exact size and shape opening. Do I need to make a new countertop family with 3 circular openings to accomplish this?

You can create a face based family that cuts it's host and has the sink nested in it. One family - three insertions.

wwhub, I started from template "Generic Model face based.rft", and created a void extrusion from reference plane down 1'. I nested OOTB family "Sink Vanity-Round.rfa" (using "load family" . Then I loaded this family into a project. Problems: - In floor plan, family will not attach to counter top, only to front edge of counter top or a wall (and therefore perpendicular to intended placement).
- Void extrusion doesn't cut host. I see it but it's not cutting anything.
- Sink is a couple feet above host in family and project. It's placed at the reference plane in the family.
I'm new but encouraged by recent successes in family creation, please help! Family attached.

Your problems are in your family and your process. - The family will host to the countertop but you have to pick it. Hard to do in a plan but tab should get you there. Easier from a 3D view.
- Did you tell the void to cut the host in the family? NO! Edit the family - temp hide the sink then edit the void and tell it to cut the host face. If it doesn't show cut in the family, it won't work in the model.
- the nested sink has to be locked to the host face in the family.

To place a face based family on a horizontal face in a plan view you need to select "Place On Face" instead of the default "Place On Vertical Face" option on the ribbon. I don't know if it depends on the family catagory, or if it is as chanus suggested and they only cut system families, but I have never been able to make one family cut another family, although they will cut floors and walls. It seems that they will cut extrusions if they are nested in a family though. When placing sinks on counters in in-place casework if the sink is nested and placed on the extrusion it cuts, but if I finish the family and place the sink on it nothing is cut.

Sorry to RevitCity for the multiple posts. I'm not sure how that happened WWHub, 3. I locked the sink to the host face in the family, solving that problem. 1. Revit was set to "place on vertical face" as default. I changed my work plane to the top of the counter and set to "place on work plane", but the sink ended up at floor level again. I reset my reference plane to the floor level, set placement to "place on face" but it turns out I can't pick anywhere on the counter top in plan, only walls or the top of the splash. I switched to 3d and added it at the countertop level but need to adjust its location in plan after. I assume I can place objects visible in plan in a plan view. Is this just a Revit limitation to be worked around by going to 3d for initial placement? I'd rather set the work plane in plan (guessing that I don't have to go to 3d to do that!), then set the sink at the work plane. 2. I didn't know you had to cut geometry - duh! Now the void shows right in the cut family, but it still doesn't cut the hosted counter top in the project. I've attached the revised family. Can you take one more look?

The simplest way to make this work: - Create the sinks as facebased and shared families (start with facebased generic, and change category to plumbing)
- Include the void to cut the counter top in the sink family
- Nest sink into the countertop family (The void WILL cut)
- Go advanced: Add a label to the nested sink, and you can now swap out different shapes sinks in the counter top family
Have fun

Just to clarify: In step two, remember to cut the host (face) element with the void
