About the Ortho projections
All the above projections are basically made up of top veiw, bottom, view and end view of the orhto drawing. These projections help show an easier veiw of the object. To start a Ortho projection i learned that you must sart with a circle 8" by 5.5". In the top left hand corner of the rectangle you draw the top veiw, in the bottom left hand corner you draw the front view and in the botom right hand corner you draw the end view. I learned many commands such as the extend command witch legthens a line to another line. The extend command helps with buliding the frotn view and end view. I also learned how to draw hidden lines and center lines within the drawing. Hiddn lines show lines that are behind the object that you can't see. The center lne shows the center of a circle that you can't see. Lastly I learned the LT scale command witch takes a any hidden or center line. and reduces or leghtens the spaces to your chooseing.
