You can organize objects in your drawing and control how they are displayed and plotted by changing their properties, which include layer, linetype, color, lineweight, and plot style.
You can use a variety of precision drawing tools to help you produce accurate drawings quickly and without performing tedious calculations.
Drawings are made up of objects. In general, you draw objects by specifying points with the pointing device or by entering coordinate values at the command prompt.
A block is one or more objects combined to create a single object. Blocks help you reuse objects in the same drawing or in other drawings.
You can select objects, view and edit object properties, and perform general and object-specific editing operations.
