If some automatically generated area boundary lines are incorrect, what should be done to correct them?

Using the Area Boundary tool to create the correct area boundaries is the appropriate approach when automatically generated area boundary lines are incorrect. This tool is designed specifically for defining areas within your Revit model, allowing you to manually draw or adjust boundaries to achieve the desired configuration of spaces.

When the automatic generation of area boundaries does not reflect the intended design or layout, utilizing the Area Boundary tool provides a straightforward method for rectification. This tool enables you to sketch new boundaries accurately based on your design requirements, ensuring that the area calculations align with what is represented in your architectural intentions.

Other options may not be as effective. For instance, placing areas in the correct locations and then editing the area sketches could still leave underlying issues with the boundary representation. While it may appear to provide a solution, it relies on correct placement first, which may not resolve boundary inaccuracies.

Activating the Room Separator tool could be a useful strategy for different purposes, such as defining spaces within a larger room, but it is not specifically intended for correcting area boundaries.

Creating a new area scheme and re-creating the area plan could potentially involve a cumbersome process without necessarily resolving the inaccuracies of existing boundaries. It also doesn't directly address the immediate issue of correcting the existing area boundaries you have already placed
