Missing Elements in 3D?

Have you ever open your file and everything is showing up right in the floor plan view until you get to the 3D and some elements are missing? It’s really likely those elements are being filtered out in the 3D View.
You can easily check this within Filter and Cut Elements in 3D dialogue box, in here you will be able to show or hide elements by their category, making it a pretty handy tool, but also the reason behind not elements showing up in the 3D View sometimes.

I hope you find this option useful next time some elements disappeared in the 3D Window.
