Revit 2015 offers a simple tool, from within the Revit interface, to import a custom assembly code file. Now, assembly code trees utilized in Assemble can be exported from Assemble and imported into Revit in a few quick and easy steps, allowing undeviating assembly descriptions of your model elements.
Assembly code files imported into Revit are model-specific when using Revit's new Assembly Codes Settings tool, and will not affect all models opened in Revit.
Note: Revit's Assembly Codes Settings tool will ignore codes beyond Level 5.

2. Select the Assembly Codes link in the resulting pane.
3. At the bottom of the Assembly Codes window, click the blue Export link.
