Part 1: Getting Started with Basic Drawings

AutoCAD Interface

• AutoCAD comes in two versions:
  • Autodesk AutoCAD 2020 (complete version)
  • Autodesk AutoCAD LT (lighter version with limited features, no 3D tools or sheet sets)
• Interface may differ slightly on Mac vs Windows but functions are similar.

Starting a New Drawing

• Click "Start Drawing" to open a new tab.

Interface Components

• Application Button: Top left, contains frequently used tools.
• Quick Access Toolbar: Similar tools to the application button.
• Tabs and Ribbon Area:
  • Tabs include Home, Insert, Annotate, Parametric, etc.
  • Each tab has panels containing tools and commands.
• Drawing Area: Main area to create drawings.
• Command Bar/Command Line: Area for typing commands.
• Status Bar: Toggles for making precise drawings.

Making Your First Drawing

• To draw a line:
  • Select line tool or use command alias (type "l").
  • Follow prompts in the command line to specify points.
  • Press "Enter" to finish the command.

Navigation Tools

• Use the middle mouse wheel to:
  • Pan the drawing (press and hold middle mouse button).
  • Zoom in/out by rolling the wheel.
• Select objects by clicking them, deselect with "Escape".

Selection Methods

• Window Selection: Drag a solid rectangle around objects to select.
• Crossing Window Selection: Drag a dashed rectangle; selects objects that touch the boundary.
• Lasso Selection: Hold left click and move mouse to draw a freeform selection area.

Setting Up Units

Drawing Basics with Line Tool

• Start a line with:
  • Command alias "l" or select line tool.
  • Click to specify points.
• Specify lengths and angles directly in the command line.
• Polar Tracking: Set angles for drawing at specific intervals (e.g., 30, 60 degrees).
• Dynamic Input: Activate with F12 to show tooltips for length and angle as you draw.

Conclusion

• Basic drawing tools and navigation in AutoCAD discussed.
• Next video will cover additional draw and modify tools.
