  1. Blueprint Reading for the Machine Trades, Sixth Edition Unit 12: Auxiliary Views Russ Schultz and Larry Smith PowerPoint presentation created by LaVonne Vichlach

  2. Auxiliary Views • Auxiliary views show the true shape • True Shape is needed for dimensioning • Does not always create an additional view on a drawing • Can be used to replace one of the principal views

  3. Inclined Planes • Appears as an edge in a principal view • True shape may be shown by projecting a view perpendicular to it • Accomplished by drawing a primary auxiliary view • Often drawn as partial views-exposing only true shape of inclined plane

  4. Inclined Planes • Partial views may terminate with short break lines • May terminate with visible lines where applicable • May use existing visible lines where applicable

  5. Angle BRKT 1. What type of iron is specified for the casting? (Do not abbreviate.) Malleable Iron

  6. Angle BRKT 2. What principal view did the auxiliary view replace? Right-Side View

  7. Angle BRKT 3. Is the auxiliary view a partial view or is it complete? Partial View
