Final answer:
To hide a component in an assembly while using CAD software, press the Tab key. This function is helpful for focusing on specific parts and accessing hard-to-reach components.
Step-by-step explanation:
While hovering over a component in an assembly, press the Tab key to hide it. This functionality is commonly found in 3D CAD (Computer-Aided Design) software like SolidWorks, Autodesk Inventor, or PTC Creo. This feature is particularly useful during the design process when you need to focus on specific parts of an assembly without the obstruction of other components. It can also assist in easily accessing parts that are otherwise difficult to select due to their position within the assembly.
