Why does Navisworks not show Revit ceiling grids? When you append a nwc file from the architect, the ceiling typically shows up as a solid plane. It has a thickness, but not much else. There is no grid.
People who participate in the 3D coordination process want to see the ceiling grid. The grid appears on the drawings. They show up on the pdfs. Why does Navisworks hide them?
It’s not Navisworks. Navisworks uses data that it is given. In Revit, the “grid” is a pattern applied to a solid. It’s like a hatch, which is an annotation. Why is this? Why is the 3D design program not designing a 3D ceiling grid?
The answer is pure efficiency. It doesn’t need too. Revit lives for efficiency, despite the notably huge file sizes. If a pattern can display on a surface when rendered in the desired detail, that’s all that matters. The parameters contain the properties of the ceiling. This gives the installer all of the information they need.
If you want a 3D in your coordination model, what do you do? The answer is “workaround”. I think Autodesk created this term. At least, it was created because of Autodesk. A software cannot be all things to all people. Creative people create what they need from what Autodesk gives them.
“Sloped glazing” is the answer. Sloped glazing is a roof family. That’s right. You are using a roof for your ceiling.
Sloped glazing has the unique advantage of being able to use curtain walls. Curtain walls have mullions. Mullions are grids. See where I’m going with this? Sloped glazing is sloped. You can slope it to horizontal.
Therefore, to make a “ceiling” with a 3D grid, create a sloped glazing with a 2ft by 2ft grid, and a small “T” shaped mullion. Want the details? Check out my video here.
