The use of section views are powerful aids in the design and documentation of products and construction. There are many different types of section views that can be used to describe parts. Standards and conventions must be closely followed when creating section views. | Section Views Section View Shows interior detail of a part Used when hidden lines tend to confuse the interior detail of part Section View Process Pass a cutting plane through part Take viewing direction normal to cutting plane Remove that portion of object between viewer and plane Section View Notes - 1 Cutting plane seen on edge shows location of section Viewing direction for section view indicated by sight arrows drawn perpendicular to cutting plane Seen on edge, cutting plane represented as thick line with two dashes Section View Notes - 2 Hatching used to indicate interior parts of object through which cutting plane passes Section View Notes - 3 Lines that would be visible after making cut are shown on a section view Hidden lines are normally not shown on a section view Kinds of Section Views Full Half Offset Broken Out Revolved Removed Aligned Assembly Half Sections - 1 With symmetrical objects, not always necessary to pass the cutting plane all the way through part In a half section cutting plane passes half way through the part Half Sections Half Sections - 2 One quarter of part is removed in a half section Centerline separates two halves External features included on un-sectioned half Hidden lines normally omitted in both halves Offset Sections An offset section is a full section used when important features do not lie along same plane Cutting plane offset to pass through important features Change of plane lines not drawn in sectioned view where the cutting plane bends 90 degrees Offset Sections Broken Out Sections Broken out section used when only a portion of part needs to be sectioned Break line (jagged, freehand) separates sectioned from un-sectioned portion of drawing Revolved Sections In a revolved section, a cross section is revolved 90 degrees about an axis of revolution Centerline used to indicate axis of revolution Section view superimposed on multiview view Lines adjacent to revolved view drawn broken out or using conventional breaks Removed . | Section Views Section View Shows interior detail of a part Used when hidden lines tend to confuse the interior detail of part Section View Process Pass a cutting plane through part Take viewing direction normal to cutting plane Remove that portion of object between viewer and plane Section View Notes - 1 Cutting plane seen on edge shows location of section Viewing direction for section view indicated by sight arrows drawn perpendicular to cutting plane Seen on edge, cutting plane represented as thick line with two dashes Section View Notes - 2 Hatching used to indicate interior parts of object through which cutting plane passes Section View Notes - 3 Lines that would be visible after making cut are shown on a section view Hidden lines are normally not shown on a section view Kinds of Section Views Full Half Offset Broken Out Revolved Removed Aligned Assembly Half Sections - 1 With symmetrical objects, not always necessary to pass the cutting plane all the way through part In a half .
