Essential AutoCAD Commands Explained Simply

If you are learning AutoCAD or want to boost your productivity, knowing the right commands can save you hours and unlock powerful features you might not even know exist. Whether you are just starting or are a seasoned professional, mastering AutoCAD’s essential commands is key to speedy, accurate, and efficient drafting.

Essential AutoCAD Commands

1. Keyboard Shortcut Keys: Speed Up Your Workflow!

• Ctrl + N – Instantly open a new drawing tab.

• Ctrl + S – Save your current drawing quickly.

• Ctrl + Shift + S – “Save As” to create a new version of your file.

• Ctrl + 1 – Open the Properties palette for editing object details.

• Ctrl + 2 – Access the Design Center to drag and drop blocks right into your drawing.

• Ctrl + 9 – Show/hide the command line.

• Ctrl + Tab – Switch between open drawings effortlessly.

• Ctrl + C/V/Z/Y – Copy, paste, undo, redo—just like other Windows programs!

• Ctrl + Shift + V – Paste as a block for easy reuse.

Tip: Using keyboard shortcuts can significantly cut down your repetitive actions.

2. Status Bar Toggles: Control How You Draw

Function keys and system variables help control AutoCAD’s interface for precise drafting:

• F3: Turn object snap on/off so you can easily snap to endpoints, midpoints, and more.

• F8: Toggle Ortho mode for perfectly horizontal or vertical lines.

• F9: Snap Mode—makes your cursor jump to set grid points.

• F10: Switch polar tracking for drawing at specific angles.

• ISODRAFT & F5: Activate isometric drawing planes.

• LWDISPLAY & TRANSPARENCYDISPLAY: Show/hide lineweights and object transparencies.

• SELECTIONCYCLING: Easily select overlapping objects in complex designs.

3. Basic Drawing Commands: Foundation for Every Drawing

These form the backbone of nearly every AutoCAD drawing:

• L: Draw a simple line.

• PL: Create a polyline—useful for connected straight or curved segments.

• REC: Draw a rectangle.

• C: Make a circle.

• ARC: As the name suggests, draw arcs.

• POL: Create a polygon (3–1024 sides!).

• TR/EX: Trim or extend lines as needed.

• CO: Copy objects.

• B: Define a block for repeated objects.

• F/CHA: Add fillets (rounded corners) or chamfers (angled edges).

• LA: Manage layers for better organization.

Text and annotation:

• DT: Single line text.

• MT: Multiline text for paragraphs.

• DIM: Create a variety of dimension types.

• POINT (PO): Mark single points for reference.

4. General and Productivity Commands

• COUNT: Instantly count blocks in an area or the whole drawing.

• PEDIT: Edit polylines or join lines into polylines.

• MULTIPLE: Repeat a command until stopped (Escape key).

• NCOPY: Copy nested objects from blocks/xrefs without exploding them.

• OOPS: Bring back the last deleted object—even after further editing!

• QSELECT: Filter and select objects by type, layer, color, or other properties.

• CHSPACE: Move objects between model and paper space quickly.

• DIVIDE: Place equally spaced points along a curve.

• LIST: See detailed properties of selected objects.

• BASE: Change your drawing’s base point for future inserts/Xrefs.

• AREA: Calculate the area of any shape or boundary with a quick command.

• BOUNDARY: Extract closed boundaries from areas—very useful for measurement or hatching.

5. Performance Optimization Commands

AutoCAD can slow down with complex or messy drawings; these commands keep files clean and fast:

• PURGE: Remove unused blocks, layers, and other objects.

• LAYDEL: Delete stubborn layers (use carefully!).

• OVERKILL: Clean up overlapping or duplicate lines for cleaner files.

• AUDIT/RECOVER: Check for and fix drawing errors.

• DS: Change drafting settings like snapping, grid, and polar tracking.

• SAVEALL: Quickly save all open files.

• CLOSEALL: Close all files at once, with a prompt to save changes.

• FILLMODE: Show/hide fillings to boost performance in heavy drawings.

System Variables: Control interface detailing (e.g., PICKBOX size, ZOOMFACTOR, SELECTIONPREVIEW) for smoother navigating and editing.

6. Accessibility and Advanced Management

To manage layers, drawing organization, and repetitive tasks:

• LAYMCH: Quickly change the layer of selected objects.

• LAYWALK: Visualize what’s on each layer; great for cleaning up complex projects.

• GROUP/UNGROUP: Treat multiple objects as a single selectable unit.

• FIELD: Automate text and data in your drawings for smarter documentation.

• WBLOCK: Export portions of your drawing for reuse or sharing.

• PUBLISH: Print or share multiple sheets at once.

• TCOUNT: Add numbered or bulleted lists to annotation.

• ID: Find a point’s accurate coordinate quickly.

7. 3D Modeling Commands

Unlock AutoCAD’s 3D capabilities for everything from concepts to finished models:

• EXT: Extrude 2D objects into 3D.

• REV: Revolve 2D profiles around an axis to model objects like bottles or vases.

• SWEEP/LOFT: Create 3D objects along paths or by lofting between shapes.

• BOX, CYL, PYR: Quickly create common 3D solids.

• THICKEN: Add thickness to a surface, making it a solid.

• CONVTOSOLID: Turn mesh or surface models into solids.

• XEDGES: Extract 2D edges from 3D objects.

• SECTIONPLANE: Create section views of your model.

• FLATSHOT: Convert 3D views to 2D for detailing.
