What is the primary purpose of the 'Replace Feature' command?

The primary purpose of the 'Replace Feature' command in Siemens NX is to substitute bodies and datums in the model. This command allows users to replace an existing feature with a new one, ensuring that the new feature is integrated seamlessly into the existing design. When using this command, the system typically maintains the relationships and dependencies associated with the original feature, which is crucial for ensuring design integrity and continuity.

This functionality is especially useful in complex assemblies where certain components may need to be updated or swapped out without having to reconstruct the entire model. By utilizing the 'Replace Feature' command, users can efficiently manage changes to their designs while preserving important context and constraints.
