What term describes the component that is currently active in a design file?

The term that describes the component currently active in a design file is "Active Component." This designation indicates that the particular component is the focus of user interactions and modifications at that moment. When you are working within software like Autodesk, the active component can be manipulated directly with commands and tools available in the interface.

This functionality allows users to differentiate between multiple components in a complex design, ensuring changes are efficiently applied to the intended part of the design. Recognizing the active component makes it easier to manage the design workflow and minimizes the risk of errors, as users can clearly see which part of the model they are currently affecting.

Other terms like "Current Object," "Selected Feature," and "Primary Component" can describe similar concepts but do not precisely convey the status of being actively engaged with the design tool in the workspace. Each of those terms may relate to selection or emphasis but does not specifically highlight the component's active status in the context of design software.
