Libraries
Hatches
With the Hatch command, you can choose from a wide range of predefined and customizable hatch patterns and add them to your project. A clear example is a tile pattern: using hatches, a tiled wall can be created and visualized precisely according to the desired tile dimensions.

Content Explorer
The Content Explorer allows you to organise your libraries efficiently. Not only does it make it easier to find families, but it also offers a wide range of additional functions. The Content Explorer supports both external families and system families such as walls, floor slabs, hatches and materials. Other documents, such as Office files and PDFs, can also be stored.
An additional advantage of the Content Explorer is the ability to manage multiple libraries, including the content libraries integrated into Revit.
