Post Reply Close Saving..... Edit Comment Close By: toddje (16 month(s) ago) I really like this presentation. I am a high school teacher at a small high school in SD and I am always looking for great and simple teaching tools in my CAD class. This is a great beginners tool in 3-view drawing, could I have you send me a copy to my email. Thanks for you time and effort. todd.jenkins@k12.sd.us Saving..... Post Reply Close Saving.....

Monge worked as a drafter in the fortification design office of the school at Mezier for French army officers His work was kept a military secret for a number of years until he was allowed to publish in 1795. Stone cutters were the first to adopt his methods. Later carpenters and other trades abandoned their old methods for orthographic projection.Revolving an Object to Produce the Six Basic Views: Revolving an Object to Produce the Six Basic ViewsProjection of an Object: Projection of an ObjectThe Glass Box: The Glass Box Imagine that the object you are going to draw is positioned inside a glass box, so that the large flat surfaces of the object are parallel to the walls of the box. From each point on the object, imagine a ray, or projector perpendicular to the wall of the box forming the view of the object on that wall or projection plane.The Glass Box: The Glass BoxUnfolding the Glass Box: Unfolding the Glass BoxUnfolding the Glass box: Unfolding the Glass box For Third Angle Projection (the method in the U.S.) Imagine that the walls of the box are hinged and unfold the views outward around the front view. This will give you the standard arrangement of views for 3rd Angle Projection which is used in the US, Canada, and some other countries.The Six Basic Views: The Six Basic ViewsSlide11: Why must views be arranged so that they align? To make it possible for someone to interpret the drawing. TOP LEFT FRONT RIGHT BOTTOM REAR The Standard Arrangement of ViewsTransferring Dimensions: Transferring DimensionsUsing a Miter Line to Transfer Depth: Using a Miter Line to Transfer Depth 1. Draw miter line at 45 degrees at a convenient distance to produce the desired view.Slide14: 2. Sketch light lines projecting depth locations for points to miter line and then down into side view as shown. Slide15: 3. Project additional points, surface by surface. Slide16: 4. Draw the view locating each vertex of the surface on the projection and miter line. Necessary Views: Necessary Views A sketch or drawing should only contain the views needed to clearly and completely describe the object. Choose the views that show the shape most clearly, have the fewest hidden lines, and show the object in a usual, stable, or operating position. One view drawing of a shim One view drawing of a connecting rodPosition of Side Views: Position of Side Views An alternative postion for the side view is rotated and aligned with the top view.First Angle Projection: First Angle ProjectionSymbols for 1st & 3rd Angle Projection: Symbols for 1st & 3rd Angle Projection Third angle projection is used in the U.S., and CanadaSummary: Summary The six standard views are often thought of as produced from an unfolded glass box. Distances can be transferred or projected from one view to another. Only the views necessary to fully describe the object should be drawn. You do not have the permission to view this presentation.
