Presentation Transcript

1. Blueprint Reading for the Machine Trades, Sixth Edition Unit 5: Orthographic Projection of Inclined Planes Russ Schultz and Larry Smith PowerPoint presentation created by LaVonne Vichlach

2. Foreshortened Views • Inclined angles are at right angles to two of six principal views • Appears as an edge on those two views • Remaining views are foreshortened

3. Foreshortened Views • Plane a appears as edge in top and bottom views • Foreshortened in other four-twice visible and twice hidden • Always study adjacent views to determine true shape

4. Foreshortened Views • Line “E” is created by the edge of principal plane “V” • Both surfaces in the right hand view represent the true shape

5. Foreshortened Views • Line “I” is created by the intersection of inclined plane “W” and the principal plane “X” • The right hand view represents one foreshortened and one true shape

6. Foreshortened Views • No line is created when curved surface “Y” runs tangent with the principal plane “Z” • Combines foreshortening and true shape

34. Angular Dimensions • Inclined planes dimensioned two ways • Coordinate method • Angular method • Angular method uses one linear and one angular dimension-allows variation to increase with distance from vertex • Coordinate controls accuracy more than angular

35. Angular Dimensions • Most angular dimensions held from vertical or horizontal centerline • Easy to calculate other angle from 90 • All triangles have 180 

36. Angular Dimensions • Right triangle always has 90 angle • Other two angles add up to 90 • 180 total in triangle

37. Angular Dimensions • Isosceles triangle has 2 sides equal • Two angles are also equal

38. Angular Dimensions • Equilateral triangle has three equal sides • Also has three equal angles
