Here are some basics of AutoCAD to get you started:

1. *Interface Overview*
**Command Line**: Where you input commands directly.
**Toolbars**: Quick access to commonly used tools.
**Ribbon**: Organized panels with tools for drawing, modifying, and annotating.
**Drawing Area**: The main space where you create your designs.

2. *Basic Commands*
**LINE**: Draw straight lines.
**CIRCLE**: Create circles by specifying the center and radius.
**RECTANGLE**: Draw rectangles by defining two corners.
**POLYGON**: Create multi-sided shapes.
**TRIM**: Cut off parts of objects.
**OFFSET**: Create parallel lines or curves at a specified distance.

3. *Drawing Tools*
**Snap**: Helps in aligning objects.
**Grid**: A visual aid to maintain alignment and scale.
**Ortho Mode**: Restricts cursor movement to horizontal or vertical directions.

4. *Layers*
Use layers to organize different types of drawings (e.g., walls, electrical, plumbing). You can set colors, linetypes, and visibility for each layer.

5. *Dimensions and Annotations*
**DIMLINEAR**: Add linear dimensions to your drawing.
**TEXT**: Insert text annotations.
**LEADER**: Create arrows pointing to specific areas of your drawing.

6. *File Management*
AutoCAD files typically use the .dwg format. Learn to save, open, and manage your files effectively.

7. *Printing and Plotting*
Set up your drawings for printing by defining the plot area, scale, and paper size.

8. *3D Basics*
Use commands like *EXTRUDE* and *REVOLVE* to create 3D models from 2D shapes.

9. *Shortcuts and Efficiency*
Familiarize yourself with keyboard shortcuts to speed up your workflow. For example, "L" for LINE, "C" for CIRCLE.

10. *Practice*
Start with simple projects to get comfortable with the interface and commands. As you gain confidence, gradually take on more complex designs.

Exploring tutorials and resources online can also help deepen your understanding of AutoCAD. Happy designing!
