In Revit, which tool allows for easy placement based on existing geometry?

The Pick Lines tool is designed specifically to streamline the process of placing new geometry in relation to existing elements within a Revit model. By utilizing this tool, users can easily select edges, curves, or lines from existing geometry to create new lines or features that are accurately aligned and dimensionally consistent with the pre-existing design. This ensures a higher level of precision and efficiency when building complex models, as it reduces the potential for errors that can arise from manual input.

Meanwhile, the Align Tool primarily specializes in aligning two elements or adjusting the position of one element to match another, but it does not aid in the creation of new lines or geometries as directly as the Pick Lines tool does. The Offset Tool is used to create parallel lines or shapes at a specified distance from existing geometry, which is useful but does not specifically focus on the direct selection of existing lines for placement. The Split Element Tool is meant for dividing existing geometry into separate parts, which is unrelated to the initial placement of new geometry based on existing elements. Therefore, the Pick Lines tool stands out as the most appropriate choice for easy placement in relation to existing geometry in Revit.
