1. Front, Top, Side Holes & Curves Isometric

2. Technical Drawing: the practice or skill of portraying objects in a precise way using certain techniques. Technical Drawings tell us the following: Shape Size of Objects Types of material that object is constructed of Finish of Objects Assembly

3. Orthographic/MultiviewPictorial

4. 6 Views of an Object

5. When we draw objects, we should only include the views that are needed to fully describe the object Shape of the object Shape of features When we draw, convention is to use the right side view over the left side view if they both show the object equally well Likewise, the top view is preferred to the bottom view if they both show the object equally well Showing only the necessary views saves time, makes the drawing less cluttered, and makes the drawing easier to interpret

6. Primary Views: top, front, right side Secondary Views: Left side, rear, bottom There is always one dimension in common between adjacent views 4 angles of projection. Third angle projection is the multi-view setup used by the U.S.A. First angle projection is used in Europe.

7. Creating a Three-view sketch: Step 1: Block in the front, top, and right side views. Sketch the front view first using construction lines to project dimensions Step 2: Lightly block the major features in views Step 3: Use construction lines to project the location and size of features between views Step 4: Finish adding the final lines Step-by-step

9. Lines with short, evenly spaced, dashes Indicate edges that you cannot see in a view

10. Thin lines of alternating, long and short, dashes Show centers of holes and axes of symmetry

13. Visible Lines Hidden Lines Center Lines Practice!
