## Diedric SystemPresentation Transcript

• Diedric system Technology 1º ESO 30/11/09 Baldo - Technology
• The Diedric system represents figures using a perpendicular projection on a plan.
• The projection or view consists of drawing what you see when you are perpendicular to the figure and to the plane.

• Views of a figure
• FRONT: You see the figure from the front.
• FLOOR: You see the figure from the top.
• LEFT PROFILE: You see the figure from the left side.
30/11/09 Baldo - Technology
• First, you have to define the front view, the left profile view and the floor view of the figure.
30/11/09 Baldo - Technology How to draw the views of a figure
• Drawing the axes
• Second, you have to draw the axes. The axes are two perpendicular lines.

• Cautions
• Draw all the views with the same scale.
• The height on the front and on the profile view is the same.
• The width on the front and on the floor view is the same.
30/11/09 Baldo - Technology
• Hidden sides – Discontinuous lines
• When there is a non visible line in the figure we draw the hidden line on the view using a discontinuous line.

• Take an object, turn it and watch the different views carefully.
• TRICK: put the object at eye level and cover one eye.
