The REGION command is used to convert closed objects such as polylines, polygons, circles, ellipses, closed splines, and donuts into two dimensional regions. After we create a region, we can then modify it using various three dimensional tools.
The EXTRUDE command is used to create 3D solid or surface by extruding the dimension of selected object. For example, a circle can become a cylinder, a line can become a 3D plane, and a rectangle can become a box.
Imagine that we have selected some objects and are ready to edit them but cancel the selection by mistake. Can we get the selection back? Just execute the CHANGE command, and when we are prompted to select object, type P and then press Enter, we will get the canceled selection back.

The M2LVPORT or Layout Viewport allows us to create a viewport on layout space by selecting objects from the model space and locate the viewport somewhere we’ve chosen in the layout space. By doing this, we can quickly create and setup a viewport for the current drawing.
