Final answer:
The Center Rectangle tool adds centerlines when drawing a rectangle in CAD programs, providing a center reference for both the height and width of the rectangle.
Step-by-step explanation:
The Center Rectangle tool is the type of rectangle sketch tool that adds centerlines when the sketch entity is drawn in various CAD (Computer-Aided Design) programs, such as SolidWorks or AutoCAD. When using this tool, you start by defining the center of the rectangle, then you define the size by dragging out to one of the corners. As you do so, the software automatically adds centerlines that represent the midpoints of the rectangle's height and width, providing a useful reference for further design work.
In contrast, the Corner Rectangle tool starts from one corner and requires you to specify the opposite corner. The 3 Point Corner Rectangle starts with specifying two points to determine one of the rectangle's edges and a third point to define the opposite corner, without automatic centerlines. The Parallelogram tool is used to create a parallelogram by defining the corners, also without automatic centerlines.
