Essential AutoCAD Keyboard Shortcuts, Function Keys & Command Aliases
Comprehensive guide to essential AutoCAD keyboard shortcuts: core 2D drafting aliases, modifier keys, F1-F12 function toggles, and step-by-step PGP customization for drafting speed.
⚡ Quick Answer / Key Takeaway
Top AutoCAD shortcuts: L (Line), PL (Polyline), C (Circle), REC (Rectangle), M (Move), CO (Copy), RO (Rotate), TR (Trim), EX (Extend), O (Offset), F (Fillet), SC (Scale), MI (Mirror), H (Hatch), B (Block), XR (Xref), Ctrl+1 (Properties), and F3/F8 (OSNAP/ORTHO).
Step-by-Step Instructions & Commands
1. Essential 2D Geometry Creation Aliases
L: Line | PL: Polyline | C: Circle | A: Arc | REC: Rectangle | EL: Ellipse | POL: Polygon | H: Hatch | REG: Region | T or MT: Multiline Text.
2. Primary Precision Modification Commands
M: Move | CO / CP: Copy | RO: Rotate | TR: Trim | EX: Extend | O: Offset | F: Fillet (use R=0 to join corners) | CHA: Chamfer | MI: Mirror | SC: Scale | S: Stretch | J: Join | X: Explode.
3. Function Key Hardware Toggles (F1 - F12)
F1: Help | F2: Command History Window | F3: Object Snap (OSNAP) On/Off | F5: Isoplane Toggle | F7: Grid Display | F8: Ortho Mode (constrain 90°) | F9: Snap to Grid | F10: Polar Tracking | F11: Object Snap Tracking | F12: Dynamic Input.
4. Customizing Your acad.pgp Command Aliases
To edit shortcuts, type ALIASEDIT (Express Tools) or open acad.pgp directly (Manage tab > Edit Aliases). Scroll to the bottom and append custom aliases (e.g., QQ, *PURGE or FF, *FILLET). Save the text file and run REINIT (check PGP file box) to load new hotkeys immediately without restarting AutoCAD.
Common Issues & Troubleshooting Guide
| Common Failure / Problem | Root Cause & Recommended Solution |
|---|---|
| Command line does not appear when typing | Dynamic Input might be off or the command window was closed. Press Ctrl+9 to toggle the Command Line window back on. Press F12 to enable dynamic heads-up typing. |
| Custom PGP shortcuts stopped working after upgrade | New CAD versions install a fresh default PGP file. Always maintain a backup copy of your customized aliases section and paste them at the very bottom of the new version's PGP file. |
| ESC key doesn't cancel stubborn commands | If a macro or AutoLISP routine is trapped in a loop, press Ctrl+C or ESC multiple times. Check your CUI macro button assignments if a command continually relaunches. |
Cross-CAD Compatibility & Alternatives
GstarCAD and ZWCAD support full PGP alias mapping (gcad.pgp / zwcad.pgp) with 100% AutoCAD shortcut compatibility. You can directly import your AutoCAD PGP file into GstarCAD using the Customize dialog.
Engineering Best Practices Checklist
- Keep your left hand on the keyboard and right hand on the mouse for maximum drafting velocity.
- Customize single-letter or double-letter aliases for commands you invoke more than 20 times per hour.
- Master F3 (OSNAP), F8 (ORTHO), and F10 (Polar Tracking) for high-precision vector drafting.
- Use Spacebar or Right-Click as an instantaneous Enter confirmation.
