If you change the dimensions of a part, will the hole remain centered?

When changing the dimensions of a part in SolidWorks, the centering of a hole largely depends on the relationships defined in the sketch. If a relationship such as a coincident relation is established between the hole and the edges or central axis of the part, the hole will remain centered even when dimensions are altered.

Without these relationships, changing dimensions could lead to unintended shifts in the hole's position. For instance, if a circle representing a hole is simply located by its dimensions without any constraints tying it to other geometric entities, modifying the overall dimensions of the part could move the hole off-center. This principle illustrates the importance of defining relationships within sketches to maintain design intent and geometry stability in parametric modeling.

Understanding the significance of relationships in SolidWorks is essential for creating stable and predictable designs, ensuring that modifications to dimensions do not disrupt the intended layout of features like holes.
