For practical drawing in AutoCAD, understanding and efficiently using essential commands can significantly enhance your productivity. Here’s a list of fundamental commands you’ll need for creating and managing drawings:

1. Basic Drawing Commands
LINE (L): Draw straight lines between two points.
CIRCLE (C): Create a circle by specifying the center and radius or diameter.
ARC (A): Draw an arc by specifying three points or other methods.
RECTANGLE (REC): Draw a rectangle by specifying two opposite corners.
POLYLINE (PL): Draw a connected sequence of line and arc segments.
ELLIPSE (EL): Draw an ellipse by specifying the axis endpoints or a center and axis.
2. Editing Commands
MOVE (M): Move objects from one location to another.
COPY (CO): Create a copy of selected objects.
ROTATE (RO): Rotate objects around a base point.
SCALE (SC): Resize objects by a specified scale factor.
MIRROR (MI): Create a mirrored copy of objects about a specified axis.
TRIM (TR): Trim objects to meet the edges of other objects.
EXTEND (EX): Extend objects to meet the edges of other objects.
OFFSET (O): Create parallel copies of objects at a specified distance.
FILLET (F): Round the corners of objects with an arc.
CHAMFER (CHA): Create a beveled edge between two intersecting lines.
3. Dimensioning and Annotation
DIMLINEAR (DIM): Dimension linear distances.
DIMANGULAR (DIMA): Dimension angles between two lines.
TEXT (T): Add single-line text to the drawing.
MTEXT (MT): Add multi-line text with advanced formatting options.
LEADER (LE): Create a leader line with an annotation.
4. Object Creation and Management
HATCH (H): Fill enclosed areas with a pattern or solid color.
BLOCK (B): Create a block definition from selected objects.
INSERT (I): Insert a block or drawing as a block reference.
WBLOCK (WB): Write selected objects to a new drawing file.
XREF (X): Attach an external reference to your drawing.
5. View and Navigation
ZOOM (Z): Zoom in or out on the drawing.
PAN (P): Move the view without changing the zoom level.
REGEN (RE): Regenerate the drawing to update the display.
VIEW (V): Save and restore named views.
6. Layers and Properties
LAYER (LA): Open the Layer Properties Manager to manage layers.
LAYISO (LAYISO): Isolate the selected layers, hiding all others.
LAYERSTATE (LAYERSTATE): Save and restore layer states.
7. File and Drawing Management
SAVE (SAVE): Save the current drawing.
SAVEAS (SAVEAS): Save the current drawing under a new name or format.
OPEN (OPEN): Open an existing drawing file.
IMPORT (IMPORT): Import external files into the drawing.
EXPORT (EXPORT): Export the drawing to other file formats.
8. Utility Commands
DIST (DIST): Measure the distance between two points.
AREA (AREA): Calculate the area and perimeter of a closed object or region.
LIST (LIST): Display information about selected objects.
PROPERTIES (PR): Open the Properties palette to modify object properties.
9. Practical Tips
Command Aliases: Use AutoCAD’s command aliases (shortcuts) to speed up your workflow.
Object Snaps (OSNAP): Enable specific object snaps (like endpoint, midpoint) to ensure precision in your drawing.
Dynamic Input: Use dynamic input to enter commands and coordinates directly in the drawing area.
Familiarizing yourself with these commands and incorporating them into your workflow will help you become more efficient and effective in AutoCAD.
