When copying a group of faces or features, what happens to the original faces?

When copying a group of faces or features in Solid Edge, the original faces remain unchanged and intact. This means that the copied elements are independent of the originals; making modifications to the copied features will not affect the original ones. The process of copying is designed to create a separate instance that can be edited without any impact on the source geometry.

This behavior is crucial for design workflows where maintaining the integrity of the original geometry is necessary while enabling the designer to create variations or replicate certain features. In contrast to the other options, which suggest alterations or deletions to the original faces, the act of copying preserves their state, allowing for flexibility in the modeling process. This functionality is fundamental in parametric modeling environments like Solid Edge, where users often need to utilize existing geometry efficiently.
