AutoCAD is a computer-aided design (CAD) software used for 2D and 3D design and drafting. It uses tools bars, pull-down menus, key commands, and keyboard shortcuts to execute commands. Drawings in AutoCAD are organized using layers to manage different elements like hidden lines or center lines. Layers act as invisible sheets that elements are drawn on and controlled through the layer properties manager. Common commands in AutoCAD include move, copy, rotate, scale, trim, extend, break, chamfer, and fillet to modify drawing elements.

WHAT IS AUTOCAD? AUTOCAD IS A CAD (COMPUTER AIDED DESIGN OR COMPUTER AIDED DRAFTING) SOFTWARE APPLICATION FOR 2D AND 3D DESIGN AND DRAFTING.
COMMANDS TOOL BAR PULL DOWN KEY COMMANDS FROM THE KEY BOARD
KEY SEQUENCES ALWAYS LOOK AT THE COMMAND LINE AT THE BOTTOM OF THE PAGE ALWAYS BE AS SPECIFIC AS POSSIBLE
LAYERS IN AUTO CAD, WE MAKE INDIVIDUAL LAYERS, FOR THINGS LIKE: HIDDEN LINES CENTER LINES SECTION LINES BREAK LINES
LAYERS LAYERS ARE A WAY OF MANAGING, TIDYING AND ALSO CONTROLLING THE VISUAL LAYOUT OF A DRAWING.
WHAT IS A LAYER A LAYER CAN BE THOUGHT OF AS A LARGE PIECE OF CLEAR PLASTIC, AS INFINITELY LARGE AS THE DRAWING AREA IN AUTOCAD. WHEN DRAWING IN AUTOCAD, EVERYTHING IS DRAWN ON THE DEFAULT LAYER WHICH IS SET CURRENT. ONLY THE OBJECTS YOU ARE DRAWING ARE VISIBLE ON THE LAYER, THE LAYER ITSELF CAN NEVER BE SEEN - IT IS INVISIBLE. Layers are controlled by the layer properties manager button which is located on the object properties toolbar:
DRAFTING SETTINGS COMMAND DS CHANGES GRID OBJECT SNAPS POLAR TRACKING
ERASE SELECT THIS BUTTON THEN A DRAWING ELEMENT TO ERASE IT PERMANENTLY FROM THE DRAWING.
MIRROR Mirror - The mirror command will create a mirror image of any selected drawing elements along any line of symmetry specified by the user.
MOVE THE MOVE COMMAND WORKS EXACTLY THE SAME AS THE COPY COMMAND DESCRIBED ABOVE, EXCEPT INSTEAD OF CREATING A COPY OF THE SELECTED OBJECTS, THE SECOND OBJECTS ARE MOVED.
ROTATE THE ROTATE COMMAND ROTATES ANY SELECTED OBJECTS ABOUT A DEFINED POINT BY THE ANGLE SPECIFIED. BY DEFAULT AUTOCAD WILL ROTATE OBJECTS ANTICLOCKWISE WHEN AN ANGLE IS ENTERED.
SCALE THE SCALE COMMAND SCALES THE SIZE OF A SELECTED OBJECT(S) BY A DEFINED SCALE FACTOR FROM A SELECTED BASE POINT. THE SELECTED OBJECTS CAN BE SCALED UP TO INCREASE SIZE OR DOWN TO REDUCE THE SIZE.
TRIM
EXTEND THE EXTEND COMMAND IS SIMILAR TO THE TRIM COMMAND IN HOW IT FUNCTIONS, EXCEPT IT EXTENDS A SELECTED LINE TO A POINT OF INTERSECTION OF ANOTHER SELECTED OBJECT.
BREAK THE BREAK COMMAND IS IDENTICAL TO THE BREAK AT POINT COMMAND, EXCEPT THE BREAK LINE ISN'T AS NEAT AS BREAK AT POINT.
CHAMFER THE CHAMFER COMMAND WILL CHAMFER THE INTERSECTION OF TWO LINES TO A SPECIFIED DISTANCE. ILLUSTRATING FIGURE:
FILLET THE FILLET COMMAND IS VERY SIMILAR TO THE CHAMFER COMMAND ABOVE, EXCEPT INSTEAD OF CREATING A STRAIGHT LINE CHAMFER, AUTOCAD CREATES A RADIUS BETWEEN THE TWO POINTS. ILLUSTRATING FIGURE:
THANKYOU THERE ARE MORE NEVER ENDING THINGS TO LEARN IN AUTOCAD KEEP LEARNING KEEP GROWING
