THIS PRESENTATION IS A FULLY DETAILED COURSE ON STARTING YOUR AUTOCAD JOURNEY ON MACHINING AND CNC DESIGNS

1. AutoCAD 2015 and AutoCAD LT 2015 Essentials By Scott Onstott

2. Using the Navigation Bar: Pan Zoom Zoom flyout menu

3. Accessing Zoom Options: Ribbon user interface View tab Navigation panel Multiple zoom options

4. AutoCAD Zoom Virtually infinite zoom capability An infinity within every point Resolution is not compromised when zooming in or out Zoom real time Zoom window Zoom previous Zoom extents

5. Drawing Lines Typing L and pressing Enter Clicking the Line tool on the Draw panel Rubberband Continuing the LINE command with Enter or the Spacebar

6. Right Click Customization Time-sensitive right click More efficient drawing by using right click to end commands Hold down right mouse button longer to invoke shortcut menu Shortcut menu has additional choices that are useful less frequently than invoking Enter without a menu

7. Making Mistakes The Esc key cancels the active command The Delete key erases the selection There is a difference between the Delete and Backspace keys; Backspace does not erase You have unlimited Undos and Redos in a session The undo buffer is stored in RAM rather than in the file

8. Cartesian Coordinates All points in space represented in terms of x,y , and z coordinate values relative to the origin point Absolute coordinates are in relation to the origin point The # symbol signifies absolute coordinates (this is the default) Relative coordinates are in relation to the first point picked The @ symbol signifies relative coordinates

9. Polar Coordinates Polar coordinates are comprised of a distance and an angle The angle is measured from the zero angle which is East (to the right) by default The < symbol signifies an angle value Polar coordinates take the form distance<angle, i.e. 4<60

10. Fillet and Chamfer Fillet creates a tangent arc transition between two lines Fillet can be used to join lines in sharp corners when its radius value is set to zero Chamfer creates a beveled edge transition between two lines Chamfer requires two distance values
