2. Technology

   • Input
     • Keyboard
       • Used to input written information into the computer
       • Always in QWERTY layout
     • Mouse
       • Common input method for drawing package
       • Can be used with a mouse mat to help it be more accurate
     • Graphics tablet
       • Is used like pen and paper
       • Tablet senses the position of the pen and converts it to a position on the screen
       • Can be used to quickly draw onto the computer
     • Digital camera
       • Used to take photos of something
       • Photographs get uploaded to the computer
   • Process

       • Is the way that the image on your screen can come to the real world

3. Drawing techniques

   • Oblique
     • Based on the elevation view
     • View is extended back at a 45 degree angle
     • Useful for items with circles
   • Two-point perspective
     • Two points are drawn and the lines of the shape are projected towards it
   • Planometric
     • Based on the plan view rotated either by 45 degrees or 30 and 60 degrees
     • It is extended up
   • One-point perspective
     • A point is drawn and lines are extended towards it from the shape
   • Isometric
     • Horizontal lines are projected at 30 degrees from flat
     • Vertical lines are projected at 90 degrees from flat
   • Orthographic
     • Consists of plan,elevation and end elevation
     • Third angle projection symbol is used to show what view has been drawn
