What is a "Sketch Block" in SolidWorks?

A "Sketch Block" in SolidWorks refers to a group of sketch entities that are combined into a single entity, which allows for easier manipulation during the design process. This functionality is particularly useful when multiple sketch entities need to be moved, resized, or modified concurrently without affecting each entity individually. By encapsulating these entities into a single block, users can streamline their workflow and maintain better organization within their sketches.

Furthermore, sketch blocks can also be reused across different parts or assemblies, enabling designers to create consistent features quickly. This reusability, along with the convenience of manipulating entire blocks instead of individual entities, significantly enhances productivity in sketching and design tasks.
