A certificate course in AutoCAD typically covers fundamentals of both 2D and 3D design, starting with the software interface and basic drawing commands, and progressing to layers, blocks, dimensioning, and 3D modeling. Key topics include interface navigation, 2D drafting and editing tools, 3D object creation, materials and rendering, and preparing drawings for output like plotting or sheet sets. 

1. Introduction to AutoCAD and Basic Drafting

• AutoCAD Interface: Navigating the workspace, screen nomenclature, and using function keys.
• Drawing Basics: Setting units and limits, using the coordinate system, and drawing basic shapes like lines, polylines, circles, and arcs.
• Precision Tools: Utilizing the grid, polar tracking, object snap, and dynamic input for accurate drafting. 

2. 2D Drawing and Editing

• Drawing Commands: Creating and modifying complex objects using commands like rectangle, polygon, ellipse, and spline.
• Editing Tools: Using commands like trim, extend, fillet, and chamfer, as well as grip editing and arrays.
• Layers: Organizing drawings by creating, managing, and changing object layers.
• Blocks and Attributes: Creating, inserting, and managing blocks (reusable components). 

3. Annotations and Layout

• Dimensioning: Applying and editing dimensions for clear and precise measurements.
• Text and Tables: Creating and formatting text, and adding tables to your drawings.
• Paper Space: Setting up layouts, viewports, and preparing drawings for plotting or printing. 

4. Introduction to 3D Modeling

• Basic 3D Concepts: Understanding the fundamentals of 3D modeling.
• Creating 3D Objects: Building 3D objects and models using various tools.
• Rendering and Visualization: Applying materials and textures, and rendering the final 3D designs. 

5. Advanced and Project Topics

• Hatching: Using hatching patterns for sections and fills.
• Sheet Sets: Managing multiple drawings in a single project file.
• Project Work: Applying learned skills to a final project, often involving both 2D and 3D elements.
