Basic Drawing Tools
AutoCAD 2018 offers a wide range of drawing tools that are essential for creating your first designs. Here are some of the basic tools you will need to know:
Line Tool
The Line tool is the most fundamental drawing tool in AutoCAD. You can create straight lines by clicking at two points in the drawing area.
Circle Tool
To create circles, use the Circle tool, which allows you to specify the center point and radius or diameter of the circle.
Rectangle Tool
The Rectangle tool helps you draw rectangles and squares quickly by specifying two opposite corners.
Polygon Tool
The Polygon tool allows you to create multi-sided shapes by specifying the center point and the number of sides.
Basic Commands
Understanding basic commands in AutoCAD is crucial for efficiency. Here is a list of essential commands you should familiarize yourself with:
- LINE (L): Draws a straight line.
- CIRCLE (C): Draws a circle.
- RECTANGLE (REC): Draws a rectangle.
- POLYGON (POL): Draws a polygon.
- TRIM (TR): Trims objects to meet the edges of other objects.
- EXTEND (EX): Extends objects to meet the edges of other objects.
- MOVE (M): Moves objects from one location to another.
- COPY (CO): Creates a copy of an object.
- SCALE (SC): Changes the size of an object.
- ROTATE (RO): Rotates an object around a base point.
Working with Layers
Layers are a crucial part of organizing your drawings in AutoCAD. They allow you to separate different elements of your design, making it easier to edit and manage complex drawings.
Creating and Managing Layers
To create and manage layers, follow these steps:
1. Open the Layer Properties Manager: You can do this by clicking on the Layer Properties icon in the Layers panel on the Ribbon.
2. Create a New Layer: Click on the New Layer button and name your layer.
3. Set Layer Properties: You can change the color, line type, and line weight for each layer.
4. Assign Objects to Layers: When drawing, ensure that you are on the correct layer to maintain organization.
Saving and Exporting Your Work
Once you’ve created your drawing, it’s essential to save your work to avoid losing progress.
Saving Your Drawing
To save your drawing:
1. Click on the “Save” icon in the Quick Access Toolbar or press Ctrl + S.
2. Choose a location on your computer and give your file a name.
Exporting to Other Formats
AutoCAD allows you to export your drawings in various formats:
- PDF: Ideal for sharing your drawings without allowing further editing.
- DWG: The native AutoCAD format that retains all your layers and settings.
- DXF: A format used for exchanging data with other CAD software.
