1 5. Creating Sectioncal Views This week you 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

2 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.

3 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
