                           Setting up and Isometric Drawing in AutoCAD

To create an isometric drawing in AutoCAD, first change your units to architectural then change
the snap settings from rectangular to isometric.

     (1) Right click on the snap button at the bottom of the screen and open the settings window. Make
         sure the snap and grid are turned on and the snap type is set to isometric.




     (2) Your screen should now look like this. Use the snap and grid to your advantage. They may be
         useful for laying out the major portions of your home; however, when you are drawing the finer
         details, it may be easier to turn them off.

     (3) Make sure that the “ortho” command is turned on. When it is turned on your movement is
         restricted to either the vertical or horizontal planes. To switch between the planes press F5 or
         “Ctrl E”.
     (4) Begin by your drawing from one of the front corners of your home. Pick the one that will show
         the most detail and provide a good overall view of your home.
     (5) Start from the ground plane and work your way upwards. Draw all lines full size on each axis.
         Begin with the outlines of the walls and roof.
     (6) To draw your roof, begin from the outside corner and draw a triangle that follows the slope of
         your roof. Ex. If you have a 6:12 slope, first draw a horizontal line that is 12’ long and then switch
         drawing planes and draw a 6’ vertical line. Next turn off “ORTHO” and draw the edge of the roof.
         Now you can erase the legs of the triangle and extend the roof up to its peak.
     (7) Add details such as doors, windows, chimney(s), and trim work. If you have circle top or Palladian
         windows, you will need to use the ellipse command and select I to activate the isocircle command.
         This will allow you to draw isometric circles and arcs. To make an arc you can experiment with the
         arc command; however, it might be easier to use the isocircle command and trim off the portion
         of the circle that that you don’t need.
     (8) Add your landscaping, driveway, and porch
         patio. Use the files on the shared drive for
         landscaping, and patterns for brick and
         stone. You can also use hatch patterns to
         simulate other materials such as pavers,
         concrete, and grass. Use colors to make the
         drawing more realistic.
     (9) Add the exterior finish materials such as
         brick, siding, stucco and shingles. This can
         be done using the hatch and gradient
         commands. You can also find some
         materials and patterns on the shared drive.
         Use colors to make the drawing more realistic.
     (10) Finally, clean up your drawing by trimming and deleting hidden lines.
     (11) Add a title block with your name, period, date, drawing title (Final exam Dream Home
         Isometric), and scale.
