Essential AutoCAD Commands Every Designer Should Have Memorised

Speed in AutoCAD comes from the Command Line. While the Ribbon provides a visual interface for discovering tools, experienced AutoCAD users rarely click toolbar buttons — they type short command aliases directly, keeping their hands on the keyboard and their eyes on the drawing. Learning a core set of commands and their aliases is the single most impactful thing you can do to improve your AutoCAD productivity. This guide covers the essential commands every AutoCAD designer should have at their fingertips, grouped by function.

Drawing Commands

These are the building blocks of every AutoCAD drawing. Learn the short aliases — AutoCAD accepts them as soon as you type them into the Command Line, before pressing Enter.

• L — LINE: Draws straight line segments. Each click sets a new point; press Enter or Escape to end the command. The backbone of all 2D drafting.
• PL — PLINE (Polyline): Draws a connected series of line and arc segments as a single object. Use polylines for outlines, floor plans, and any closed shape you want to treat as a unit.
• REC — RECTANG: Draws a rectangle from two corner points. Type @width,height for precise dimensions.
• C — CIRCLE: Draws a circle by centre point and radius. Other options include two-point and three-point circles.
• A — ARC: Draws an arc. The default method uses three points; pressing Enter at the start continues an arc tangent from the last drawn line or arc.
• EL — ELLIPSE: Draws an ellipse by axis endpoints.
• SPL — SPLINE: Draws smooth freeform curves through control points. Useful for irregular terrain or organic shapes.
• H — HATCH: Fills a closed area with a pattern or solid fill. The Hatch dialog offers dozens of standard patterns including ANSI, ISO, and architectural patterns.
• B — BLOCK: Creates a reusable symbol from selected objects. Fundamental for symbols, title blocks, and standard components.
• I — INSERT: Inserts a previously defined block or external DWG file into the current drawing.

Modify Commands

The modify commands transform and refine your geometry. Mastering these eliminates the need to redraw objects when adjustments are needed.

• M — MOVE: Moves selected objects from a base point to a new location.
• CO — COPY: Copies selected objects. Works with multiple copies in a single command execution.
• RO — ROTATE: Rotates selected objects around a base point by a specified angle.
• SC — SCALE: Scales objects relative to a base point. Use the Reference option to scale to a known dimension.
• MI — MIRROR: Creates a mirror image of selected objects about a specified axis line.
• O — OFFSET: Creates a parallel copy of a line, arc, or polyline at a specified distance. Indispensable for drawing walls, roads, and offset contours.
• TR — TRIM: Trims objects to a cutting edge. In AutoCAD 2022 and later, TR in Quick mode trims on a single click without needing to select cutting edges first.
• EX — EXTEND: Extends objects to a boundary. Works logically alongside TRIM.
• F — FILLET: Rounds a corner between two lines with a specified radius. Set radius to 0 to create a clean right-angle join.
• CHA — CHAMFER: Creates an angled cut between two lines using specified distances or an angle.
• AR — ARRAY: Creates multiple copies of objects in a rectangular, polar, or path-based pattern. Essential for grids, bolt hole patterns, and repeated elements.
• S — STRETCH: Stretches objects by moving selected endpoints while keeping others fixed. Use with a crossing window selection.
• BR — BREAK: Breaks an object at one or two specified points, splitting it into separate segments.
• X — EXPLODE: Breaks a compound object (block, polyline, hatch, or dimension) back into its constituent parts.
• PE — PEDIT: Edits polylines — joins segments, changes width, smooths curves, or converts lines to polylines.

Annotation Commands

Professional drawings communicate meaning through text, dimensions, and notation. These commands handle all annotation tasks.

• MT or T — MTEXT: Creates multi-line text in a defined bounding box. Supports formatting, bullets, columns, and fields.
• DT — DTEXT (Dynamic Text): Creates single-line text annotations. Faster than MTEXT for simple labels.
• D — DIMSTYLE: Opens the Dimension Style Manager. Always set up a dimension style before dimensioning a drawing.
• DLI — DIMLINEAR: Creates horizontal or vertical linear dimensions.
• DAL — DIMALIGNED: Creates a dimension aligned to the angle of the measured object — useful for sloped or diagonal elements.
• DRA — DIMRADIUS: Dimensions the radius of a circle or arc.
• DDI — DIMDIAMETER: Dimensions the diameter of a circle.
• DAN — DIMANGULAR: Dimensions the angle between two lines or three points.
• LE or MLD — MLEADER: Creates a leader line with annotation text. Use for callout notes and specification labels.

View and Display Commands

Navigating and controlling how your drawing displays is critical for efficient work on complex files.

• Z — ZOOM: Controls the zoom level. Sub-options include Z E (zoom extents — fits the entire drawing in view), Z W (zoom window), and Z P (zoom previous).
• P — PAN: Pans the view without zooming. Hold the scroll wheel and drag for the same effect.
• RE — REGEN: Regenerates the drawing display, cleaning up fuzzy circles and arcs that can appear after heavy zooming.
• LA — LAYER: Opens the Layer Properties Manager.
• VP — VPORTS: Creates multiple viewports in Paper Space, allowing you to show different parts or scales of a drawing on a single sheet.

Utility Commands You Cannot Do Without

• U — UNDO: Undoes the last action. Can be applied repeatedly to step back through command history.
• CTRL+Z: Alternative undo shortcut — faster than typing U.
• QS — QSELECT: Quick Select — creates a selection set based on object type and property filters. Extremely useful for selecting all objects on a specific layer or all circles of a given radius.
• MA — MATCHPROP: Match Properties — copies properties (layer, colour, lineweight, text style) from a source object to target objects. The AutoCAD equivalent of Format Painter.
• PU — PURGE: Removes unused named objects (layers, blocks, linetypes, text styles) from the drawing, reducing file size.
• AU — AUDIT: Checks the drawing for errors and attempts to repair any found. Run this on files received from external sources.
• CTRL+SHIFT+S — SAVEAS: Saves the drawing under a new name or file format.
• CTRL+P — PLOT: Opens the Plot dialog.

Creating Your Own Shortcuts

AutoCAD’s command aliases are stored in a file called acad.pgp, which you can edit to create custom shortcuts for any command. Type ALIASEDIT to open the alias editor. Adding shortcuts for commands you use frequently can shave hours off a busy working week.

Build Your Command Vocabulary Over Time

Nobody memorises every AutoCAD command overnight. Identify the twenty commands that appear most often in your daily work and commit those to memory first. From that foundation, add new shortcuts as you encounter them. Within a few months, your hands will type commands before your brain consciously decides to — and that fluency is what separates productive AutoCAD users from those who are merely competent.

If you are ready to build that fluency with the latest version of the software, AutoCAD 2026 is available from GetRenewedTech at £39.99 for a full year of access on Windows or Mac.
