What does modifying a Sketch Entity usually entail?

Modifying a Sketch Entity typically involves adjusting the constraints applied to the sketch. Constraints play a crucial role in defining the relationships between the sketch elements, such as lines, arcs, and points. By modifying these constraints, you can control the dimensions, angles, and positioning of the sketch entities, which ultimately influences the geometry of the part being designed.

For instance, if you have a line in your sketch that is intended to be horizontal, applying a horizontal constraint will lock that line’s orientation. If you later decide to change that line's orientation, updating or removing the constraint will allow you to adjust it as needed. This flexibility in modifying constraints helps ensure that the design adheres to specific requirements and maintains the intended relationships between the entities throughout the design process.

The other choices do not pertain directly to sketch entities. Changing material properties relates to the physical attributes of the part, altering visualization style affects how the part is presented visually in the software, and rearranging assembly order pertains to the organization of components in an assembly rather than the modification of sketch entities themselves.
