The Variational Sweep command can create which one of the following?

The Variational Sweep command is primarily used to create complex shapes by sweeping a profile along a path, allowing users to define how the profile changes during the sweep. This capability is particularly useful for generating surfaces that maintain tangential continuity with other surfaces, facilitating the creation of smooth and aesthetically pleasing designs.

By using the Variational Sweep command, you can specify a sweep that adjusts the profile based on certain parameters or constraints, ensuring that the resulting surface adheres to the tangential requirements defined by adjacent geometry. This feature is essential in applications where maintaining a clean and continuous transition between surfaces is critical, such as in aerodynamic or automotive design.

In contrast, the other options do not accurately reflect the primary function of the Variational Sweep command. While creating a solid body from a sketch, generating a composite curve, and constructing a mesh model from a point cloud are useful features in NX, they pertain to different commands or workflows within the software. Thus, option B effectively captures the essence of what the Variational Sweep command is designed to accomplish, emphasizing its ability to produce a surface that is tangent to other surfaces.
