Which term is used to specify or control the size of a sketch in Autodesk Inventor?

The term used to specify or control the size of a sketch in Autodesk Inventor is "Dimensions." Dimensions define specific measurements within a sketch, allowing the designer to control lengths, angles, and overall geometric proportions accurately. By applying dimensions, users can create relationships between geometric entities, ensuring that the design adheres to specified sizes and constraints.

In Autodesk Inventor, when you add dimensions to a sketch, they indicate how big or small features should be and help maintain the proportionality of the sketch elements. These dimensional annotations can be easily adjusted, which modifies the geometry dynamically while maintaining the defined relationships. This process is integral to achieving precise designs in 3D modeling.

Other terms present in the question play different roles in the sketching and design process. For example, "Equal" is used to constrain the sizes of entities to be equal to one another, which is useful for maintaining proportions but does not directly control the size itself. "Constraints" refer to rules applied to the geometry that control its relationships and behaviors, but they do not specifically define size. "Extend" refers to a tool used for lengthening lines or curves in sketches, rather than directly controlling dimensions or sizes. Thus, the primary tool for defining specific sizes within a sketch is through
