UPDATE: This addon is not actively developed anymore.

Based on the guidelines of the RevitGG I’ve developed the Revit Wall Finish Add-in together with Arno de Lange of SEED Architects.

Currently the Add-in has the following features:

• Support for line and arc based room bounding elements
• Calculates the surface of the doors/windows to subtract from the surface
• Add-in comes with pre-build families to use as wall finish
• Search for a room or add per level wall finishes to rooms
• Options to include or exclude curtain walls and columns
