5. Creating Sectioncal Views

5. Creating Sectioncal Views This weekyou will learn creating sectional views. The steps to follow are: • Cutting Plane • Types of sectional views (full, half, detailed etc) • Hatching • Assembly Sections • Creating Section Views in CADD • Assignment #4

5. Creating Sectioncal Views Sectional views are usually produced (a) to clarify details of the object, (b) to illustrate internal features clearly, (c) to reduce the number of hidden-detail lines, (d) to facilitate the dimensioning of internal features, (e) to show the shape of the cross-section, (f) to show clearly the relative positions of parts forming an assembly.

5. Creating Sectioncal Views Cutting Plane Cutting plane lines typically lay in a view adjacent to the section view and represent the cutting path of the cross section

5. Creating Sectioncal Views Assembly Sections a) Views show how the parts fit together b) Individual components are identified by the use of numbers c) Adjacent components are hatched with a different properties (angle or scale) d) Standard components such as bolts, nuts are not hatched
