chair appears above desk in floor plan view

[julielfifield]

I started a project from the default.rte template & copied this desk & chair into the Level 1 floor plan. The chair appears to be above the top of the desk, so I made a section view to check it out. How is this possible? There is no underlay applied, & the view range & all other settings have not been changed from the original template.

In the desk family, draw a model vertical line sticking up higher than the chair back.

The issue is that the Desk Family that ships with Revit has the visibility of the Extrusion that forms the desktop set to invisible. So all you're seeing is the symbolic lines around the edge of the desktop. Open the Family, select the extrusion and change it to visible. Voila.

I have no issue with the executive chair that can be loaded from the Autodesk library. The chair in the example is a custom chair, downloaded from a website. The original suggestion worked, to force the wanted display results.

To understand this better, I compared the executive chair & the custom chair families, & the reason one displays below the desk, while the other doesn't, has to do with how the families are built. The executive chair has planes for the seat & chair back; the custom chair only has the original 3 planes that are in the family template. The way I believe Revit works, is that without the planes, Revit only has the insertion point & the overall size of the element, but cannot tell that the seat is lower than the back. Please correct me if I have this wrong.

That may well be the reason. The metric version of the Revit library does have a desk Family in it that does have the top extrusion set to invisible though so i assumed that was the cause 😉
