What command is used to combine multiple sheet bodies into a new single sheet body?

The command used to combine multiple sheet bodies into a new single sheet body is "Sew." This command is designed specifically for situations where users work with sheet bodies in Siemens NX. When you apply the Sew command, it effectively stitches together the edges of the selected sheet bodies to create a single, contiguous surface. This is particularly useful in complex modeling tasks where you need to ensure that multiple surfaces function as one cohesive entity, enabling more efficient and straightforward operations like analysis or further modeling.

The other commands do have distinct functions within the software; however, they are not intended for combining sheet bodies in the way that Sew is. For example, "Join Face" is typically used for merging face elements within a single body but does not combine multiple sheet bodies. "Unite" is primarily used for solid bodies, allowing the creation of a new solid by merging two or more solids together. "Join Sheet," while it might seem relevant, is not recognized within the typical nomenclature of NX for combining sheets like the Sew command. Thus, understanding the specific use case of each command helps clarify why Sew is the most appropriate choice for this task.
