**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**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**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**Foreshortened Views**• Line “E” is created by the edge of principal plane “V” • Both surfaces in the right hand view represent the true shape**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**Foreshortened Views**• No line is created when curved surface “Y” runs tangent with the principal plane “Z” • Combines foreshortening and true shape**Surface Identification 4**E: Edge view of surface I: Intersection of surfaces F: Foreshortened surface T: True shape Identify the condition for circle #1.

B A B D E E C**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**Angular Dimensions**• Most angular dimensions held from vertical or horizontal centerline • Easy to calculate other angle from 90 • All triangles have 180 **Angular Dimensions**• Right triangle always has 90 angle • Other two angles add up to 90 • 180 total in triangle**Angular Dimensions**• Isosceles triangle has 2 sides equal • Two angles are also equal**Angular Dimensions**• Equilateral triangle has three equal sides • Also has three equal angles**Angular Block**1.Are the inclined planes dimensioned by the coordinate method or the angular method? Angular**Angular Block**2. What is the tolerance assigned to the angular dimensions? 030’**Angular Block**3. What is the tolerance on the liner dimensions? .020**Angular Block**4. What type of line was drawn on the front and the top views to permit them to be shortened? Long Break**Angular Block**5. How many hidden lines would appear on a bottom view? 1**Angular Block**6. How many hidden lines would appear on a left side view? 0**Angular Block**7. How many inclined planes does the object contain? 2**Angular Block**8. How many principal planes does the object contain? 8**Angular Block**9. How much tolerance accumulates with dimension “A?” .04**Angular Block**10. What is the MMC of the overall height? 1.32
