After selecting paste while copying levels, what option should you choose to place the levels at the desired height?

When copying levels in a BIM or architectural context, selecting "Align Selected Levels" is essential because this option allows you to accurately position the copied levels to align with the previously established levels in your project. This ensures consistency in height and elevation across your design, which is crucial for maintaining structural integrity and ensuring that all components fit together as intended.

Using "Align Selected Levels" effectively adjusts the heights of the new levels to match the desired alignments, preventing potential discrepancies that could arise from manual adjustments. It simplifies the process of maintaining uniformity in the project's vertical dimensions, which is vital for coordination with other elements such as walls, floors, and ceilings.

The other options, while they may seem relevant, serve different purposes. "Set Level Heights" might suggest manually defining the heights but does not inherently ensure they align with existing levels. The "Level Adjustment Tool" could involve modifying levels individually rather than aligning them in bulk. "Group Levels" typically focuses on organizational aspects rather than precise height placement. Thus, the chosen option is the most efficient and effective way to achieve the desired results when working with levels in a BIM environment.
