What is the tool called that creates a new body from multiple selected bodies?

The tool that creates a new body from multiple selected bodies is known as the Combine function. This tool is particularly useful in CAD modeling environments, such as Autodesk Fusion 360, where users often need to create complex geometries by merging simpler shapes together.

When using the Combine tool, users can select various bodies to combine into a single new body, allowing for more efficient design processes and improved management of geometries. This operation not only streamlines the modeling workflow but also reduces the overall complexity of the design file by minimizing the number of individual bodies that need to be manipulated or modified separately.

The other terms, while they may describe related processes or actions within CAD software, do not specifically refer to the function of merging multiple bodies into one. This makes Combine the appropriate choice for the task of creating a new body from multiple selected bodies.
