Lecture Autodesk inventor Multiview projections 2 Treatment of common surfaces. After studying this chapter you will be able to Create a multiview drawing by sketching or CAD; represent lines, curves, surfaces, holes, fillets, rounds, chamfers, runouts, and ellipses in multiview sketches; explain the importance of multiviews.
Multiview Projections - Treatment of Common Surfaces Normal Surfaces A normal surface appears as a surface in one multiview The area of this surface is the true area of the surface In the other two multiviews, a normal surface appears as an edge Inclined Surfaces An inclined surface appears as a surface in two multiviews Not true size in either of these views In the third multiview the inclined surface appears as an edge Oblique Surfaces An oblique surface appears as a surface in all three multiviews In none of these views does the surface appear true size Single-Curved Surfaces A single-curved surface has curvature about a single axis Curvature only seen in one multiview Center lines used to indicate axis of curvature In isometric views, single-curved surfaces appear as ellipses D D Top D Front Isometric D Right Multiview Projections - Treatment of Common Surfaces ... used to indicate axis of curvature In isometric views, single-curved surfaces appear as ellipses D D Top D Front Isometric D Right Multiview Projections - Treatment of Common Surfaces ...
