What action is performed when dragging Face #1 after selecting the arrow?

When dragging Face #1 after selecting the arrow, what occurs is maintaining symmetry and coplanar relationships. This action allows you to manipulate the position of the face while ensuring that the spatial relationships between other features and faces on the part remain intact.

In Solid Edge, when you select a face and use the drag functionality, the software is designed to respect various geometric constraints, such as symmetry and coplanarity. This means that if you have features that are symmetric about a line or plane, dragging one face would also result in the other face or related features adjusting automatically to preserve that symmetry. Similarly, if the face is part of a group of faces that share the same plane, dragging it would maintain those coplanar relationships.

This capability is particularly useful during design modifications, allowing users to make changes efficiently without having to redefine relationships manually, thereby keeping the design intent intact. The other choices, such as creating a new feature, deleting an existing feature, or displaying part properties, do not accurately describe the result of dragging a selected face when geometric relationships are involved.
