The Variational Sweep command can create which type of surface?

The Variational Sweep command in Siemens NX is primarily designed to create complex surfaces that can be controlled through sketches and additional geometric influences. When you select the option that states a surface tangent to other surfaces, it highlights one of the key features of the Variational Sweep command. This capability is significant in advanced surface modeling, where maintaining tangential continuity is often crucial for aesthetic and functional surface designs.

By allowing the resulting surface to remain tangent to existing geometry, designers can ensure smoother transitions and integrate their models more effectively with surrounding features. This is particularly useful in industries such as automotive and aerospace, where aerodynamic or stylistic criteria are essential.

The other options suggest characteristics that either do not align with the command's purpose or are too limiting. For example, a non-parametric surface does not take full advantage of the parametric capabilities that Variational Sweep offers. Creating a surface controlled by only two sketches would not utilize the command's full parametric potential, as it can easily incorporate multiple sketches and references to create more sophisticated designs. Lastly, a surface normal to other surfaces is a feature more typically associated with different modeling techniques rather than what Variational Sweep specializes in.

Hence, stating that the Variational Sweep can create surfaces that are tangent to other surfaces
