I’m working in Revit 2017.

I created a sink family by starting with a generic face hosted family and later switching it to a plumbing fixture family. I am pretty happy with it other than when I host it in my counter top family, the counter top disappears in plan view.

The sink family does not make a modeled in place extrusion (substituted for a counter top) disappear.

Any thoughts on why this sink family is making the countertop lines disappear in plan would be greatly appreciated.

Attached are both families.

The problem is with the countertop family.  Edit the countertop family. Select the extrusion and click the 'Visibility Settings' button.  The extrusion for the countertop is set to not show in Plan / RCP views. Check the box to show it in Plan / RCP, then reload into your project.

Another user had this problem and posted on the Autodesk forum:

The countertop extrusion is intentially turned off in plan view. There is a masking region that represents the countertop that should show up though. The reason the countertop family is modeled this way is that base cabinets with anotative lines show up below the countertop (masking region does not hide anotative lines of other families). In this way you can see the placement of the base cabinets in plan view below the counter. If I turn the countertop extrusion to visible, it hides the base cabinets and thier anotative lines.

The link did make clear another problem I was having with not being able to place the sinks in plan view but being able to in 3D. Being that the counter extrusion is turned off in plan view (since I am using a masking region to represent it) and in a sense was trying to host a sink on a masking region, not an actual extrusion.

Thanks for the post.

It's interesting and I was aware you can do this, but it doesn't really help out in this situation and here’s why. 

If I have a transparent counter top I actually see the base cabinet extrusions below, not the annotative dashed lines of the base cabinet.

So I could make the base cabinet transparent or modeled elements not visible in plan view. Good idea but what if I have a floor material that has a hatch (say square tiles or lines to represent wood flooring. In this case, when I have a transparent countertop, I would see the floor hatch below the countertop (not ideal). So again, this circles back to why I use a masking region (in the countertop family) to show countertops in plan instead of an actual extrusion.

Trust me, I would love to use the extrusion for my counter tops, (masking regions don’t cast shadows) it just doesn't really work with how I like base cabinets to show up in plan view. The problem is (as I see it) annotative lines in a family are draw at the level of insertion (i.e. elevation 0'-0"). If you have something modeled in the model or another family, it covers up these annotative lines. If I could find a way to set annotative lines at a given height (like model lines) then I could have the annotative lines of the base cabinet show up above the extrusion of the countertop. But alas, I don't think this is possible.
