What is the primary function of the 'Align' tool in Revit?

The primary function of the 'Align' tool in Revit is to position elements with respect to other objects, ensuring precise alignment between different components within a model. This tool is essential for maintaining design integrity, especially in architectural and structural projects where elements such as walls, windows, and doors need to be accurately positioned in relation to one another.

Using the 'Align' tool allows users to select two elements: one as the reference and the other to align. This can be particularly useful for aligning edges, centers, or other reference points, enabling smoother workflows and reducing errors in placement. The tool enhances both the accuracy of the model and the efficiency of the design process, making it a vital component of Revit’s suite of features.

Other options refer to functionalities outside the domain of the 'Align' tool. Scaling objects is not a primary function of 'Align,' nor is creating patterns or generating schedules. Those tasks are handled by different tools tailored to specific functionalities within Revit.
